Seeing Double

Tree & its reflection in Don River - NEX-5N & Kodak Cine Ektar 63mm f2 C-Mount

The Kodak Cine Ektar 63mm f2 is one of the few c-mount lenses that actually covers the APS-C size sensor of the Sony NEX cameras.  Well, there is still dark corners, but considering it was designed for 16mm movie cameras, it's not bad at all.  Also, I think the image circle is even larger than the 102mm f2.7 Kodak Anastigmat.  The image towards the edge is far better than the 102mm.

The 63mm f2 is amazingly sharp, and the images coming off of this lens is wonderful, especially in colour.  In fact, it's one of my favourite c-mount lenses.  If you can get one at reasonable price, grab it and you won't regret it.

Elgeet 4 Inch f4.5 - Sample

Nice Bokeh, no? -- NEX-5N & Elgeet 4 inch f4.5 @ f4.5. Click for larger size.

When people are getting into manual focus lenses, most of them would look at the popular brands, like Takumar, Vivitar, Nikon, etc. After a while, they will get into more upscale brands like Leica, Voigtlander, Zeiss or some other brand that cost way more.  Between the popular and the expensive, there are some very overlooked lenses, particularly the American brands.  Kodak, Elgeet, Bausch & Lomb, Wollensak, Gundloch, to name a few.  I have talked about Kodak quite often and they made some of my favourite lenses.  Most people have never heard of Elgeet lenses, maybe except saw it on their grand father's 8mm movie cameras.  Indeed, Elgeet made a variety of lenses, including c-mount, d-mount, and Exakta mount.  They company still exists today, under the name Navitar, which makes optical tracking systems for the military, among many other optical products.

This is the only Elgeet lens I have, other than a few tiny D-Mount lenses I got from the Outlet Store.  But I like this 4 inch (102mm) f4.5.  It's not particularly fast, but it's very sharp at maximum aperture.  Closest focus distance is something like 6 feet, not exactly close, but common with old lenses at this focal length.   Will update when I get to use it a bit more.

Fancy Belt #2 with Carl Zeiss Jena Tessar 5cm f3.5

Fancy Belt #2 - NEX-5N & Carl Zeiss Jena Tessar 5cm f3.5 Exaktar. Click for larger picture.

The Carl Zeiss Jena Tessar 5cm f3.5 lens used in this shot reminds me how much I have missed the old Henry's Outlet Store.  My friend Paul knew I like using old and odd stuff so he would sometimes save some of these kind of lenses for me.  They usually cost $5 to $10, which was very reasonable.

This lens is about half the size of the Carl Zeiss Jena Tessar 50mm f2.8 (M42 version).  Very tiny with the same red T coating, the predecessor to the famous T* coating.  Last time I said in this blog entry that the the 50mm f2.8 was the first Tessar lens I had that had the circular aperture, and it was wrong.  This Tessar 5cm f3.5 also has circular aperture and I have had it for many years. Both Tessars are wonderful lenses and a joy to use.

Carl Zeiss Jena Flektogon 25mm f4 Sample

Reflective Wall -- NEX-5N & Carl Zeiss Jena Flektogon 25mm f4. Click for larger size.

I ventured past Bathurst Street on Queen Friday on my daily lunch-hour walk, since I have not gone that far before.  On my way back I saw this second hand store and decided to have a look.  Asked the owner if he had any old lenses, and indeed he did.  A really nice looking Flektogon 25mm f4 in Exakta mount.  It's too bad that the inside is slightly hazy, and this really would affect the flare resistance of the lens.  Anyway, since the price was pretty reasonable, I decided to buy it.  Embarrassingly, I have never heard of a 25mm Flektogon before.  Always thought that there was only the 20mm, and 35mm focal lengths only.

Indeed the lens is very sharp at f4, but the edges are not excellent sharp until f8.  The flare is as expected, pretty bad and the contrast suffers a bit in strong lights, but is totally usable for the time being until I can find some place that can clean it cheaply.

The Colours of Spring

Colours -- NEX-5N & Kodak Anastigmat 102mm f2.7

I have an unexplained addiction to old Kodak lenses.  Most of them have sweet bokeh and all of them have wonderful colours.  It is impossible to find new and modern lenses that produces this kind of effect/bokeh today.  Just too bad that many of these lenses have very choppy focusing due to grease dried up in the focusing mechanism.  Also, many of the Kodak cine lenses have an S-mount.  You will need to find the almost impossible to get S-mount to C-mount adapter to use on the EVIL cameras.

Voigtlander Nokton 40mm f1.4 Classic - First look

Voigtlander is a very old company and they used to make legendary lenses back in the days of early photography.  The original Voigtlander lenses are still very sought after in the market today.  Of course, the Cosina version of the Voigtlander lenses have very little to do with original company other than using the names of the lenses, like Haliar, Ultron, Lanthar, etc.  I have a couple of the original Voigtlander lenses, the Skopar 8.3cm f4.5, and the Color-Dynarex 135mm f4 DKL, which I like a lot.  They are not (like most old lenses in the early days) very fast lenses, but good performers. I have some sample pictures from these lenses if you search my blog for Voigtlander.

This is the first M-Mount lens I have had, though I wished I started on this a bit early, as M-Mount lens price has gone through the roof after people have discovered how good they are, and how small they look when mounted on these cameras.  No matter, I got this one for a very good price from a pawnshop, complete with original hood, which makes the lens look a lot more sexy :)

After getting the M to Sony E-mount adapter, I tried it on the NEX-5N.  Immediately I was a bit disappointed: the minimum focus distance is like three feet/one meter.  I realized most range finder lenses have pretty long minimum focus distance due to the finder limitation, but it's not something easy to get used to if you are used to the 0.5 meter normally found in most SLR standard lenses.  A side from this, there is very little not to like about this lens.  Great build and optically, it performs very well, even at f1.4 is quite OK, but there is a lot of purple fringing at wide apertures.  This can be minimized or eliminated in Lightroom or Photoshop easily.

The size and short flange focal distance of M-mount lenses have great appeal to EVIL/Range Finder camera users.  They are great lenses to take when you want to go light.  Smaller camera/lens combination is much less intimating than a huge DSLR lens mounted on a huge DSLR.  This is especially true for street shooting.  That was exactly what I did early this week.  I took it and the NEX-5N with me in an evening outing and the light weight is liberating to carry around. It was easy to snap pictures here and there.  I totally enjoyed it.

A Set of IR Pictures from High Park

On Monday I went with Dillon and Sally to High Park early in the morning hoping to photography cherry blossoms.  It turns out we didn't go at the right time yet.  Perhaps we will do it again this weekend.  It was fun as I had not gone to High Park for many years.

Took along the almost forgotten IR modified 20D with me, and the trusty Pentax-M 20mm f4.  I must say this lens is a perfect match for the 20D/IR.  A relatively wide angle of around 32mm equivalent, almost a comfortable 35mm.  I ended up shooting more IR pictures than with the NEX-5N.  Hope you like these pictures.

The Other Meyer-Optik Primotar 180mm f3.5

Back in January, I picked up another East German lens, the Meyer Gorlitz Primotar 180mm f3.5 in Exakta mount.  This mount is slightly different than the normal Exakta mount as it does not lock on to the mount/adapter.  I think it requires some sort of internal clamp on the body to hold it in place.  For this reason, I haven't really used it, until it occurred to me that there is another Primotar 18cm f3.5 that I wrote about here and here, except that's not a complete lens; it lacks the mount and barrel.

Two Primotars -- One on top is a weird Exakta mount, and one below has no mount/lens barrel.

It then dawned on me that there is a simple solution to use the non-Standard Exakta mount Primotar: Electrical tape.  First I mount the adapter on the lens, which will fit fine, but would fall off if pulled, and then taped it with electrical tape.  It worked beautifully.

This newer silver Primotar has the red V coating, unlike the incomplete lens, which is uncoated.  I took the silver Primotar to High Park yesterday, hoping we would see full blossoms of cherry trees, but only ONE tree was.  I think next week would be better.  Already, there were many people there to photograph the trees.  It turns out that the lens is pretty nice.  Love the bokeh from this lens and it's decently sharp even at f3.5.  Need a much longer hood than the one built-in, as when stray light enters the lens, the pictures appeal to be washed out.

When shooting in the shade, this lens is can produce very nice results with sharpness and contrast even at f3.5.  Again, shooting at this focal length is difficult on EVIL cameras without an EVF.  I shot with the Sony EVF on the NEX-5N and it helped tremendously.  Putting the viewfinder against my eye (glasses) helps minimize the shaking and thus much easier to focus.

Adapting Manual Focus Lenses to Your Digital Camera - Part IV

Last time we talked about adapting lenses to the M4/3 and Sony E-Mount in Part III.  This time around I am going to share some of my experiences on how to start, where to get lenses, what to avoid when buying lenses and talk a bit about adapter, and finally, why bother with manual focus lenses.  This is a long article and I was debating whether to break it into two, but decided to just leave it as one.

I shot film from early 1980s to about 2001 with only two cameras, and not at the same time!  My first camera was a Pentax Program Plus with a 50mm f1.7, and I later added the 35-70mm f4, and a Sigma 70-210mm f4-5.6 cheap zoom.  Used this setup until 1995, when I got my first AF camera - the Canon Elan II with a EF 28-105mm f3.5-4.5, which lasted until I got my first digital camera, the Canon Powershot G1.  As you can see, I did not have gear acquisition issues back then and was quite happy with what I had.  From the film camera experience, it's kind of natural for me to use manual lenses on digital SLRs.  But, many people who start using DSLRs have never touched a film camera before, so how to you start?

Getting Started

My suggestion is to start simple.  Manual focus lenses are not for everyone.  Some people get very frustrated with getting unsharp pictures from manual lenses due to focus problems, and some just like auto focus lenses more.  If I had to start today, I would buy three lenses to start with: Vivitar 28mm f2.8, Takumar 55mm f1.8 (version doesn't really matter), and a Takumar 135mm f3.5, all in M42 mount.  All these lenses should cost about $100 plus $15 for the mount of your camera.  If you don't like them, you can sell them later at little or no lost of money.  I would spend a lot of time with the Takumar 55mm f1.8, since it's one of the best manual focus lenses and it was built like a tank, and focuses like a dream, not to mention optically excellent.  Use these lenses for at least a couple of months, and see if you start to grow on them.  For people who started out using manual focus lenses with film camera, this is natural, but if you don't find yourself enjoy using them, auto focus lenses are probably a better choice for you.

Where to Buy

If you like using manual focus lenses, chances are you will not be happy with what you have for long, and the next thing you do is looking for better and more exotic lenses.   This could be both a good and a bad thing.  The good thing is that you can get some really good fast lenses for a lot less than the auto focus equivalent, and the bad thing is that you could get hooked and addicted.  But, where to get lenses?

For most people, eBay is probably the best place where you can get all kinds of lenses, but unfortunately, it's also one of the most expensive place to buy lenses.  Personally, I never bought a lens from eBay.  Just don't like competing with other people on the price.  My usual sources of lenses is Craigslist, Camera shows, Pawnshops or second hand camera stores, and occasionally, camera stores.  Some of my favourite lenses were bought from my local Craigslist, such as the JML 25mm and 50mm f0.95, Kinoptik 210mm f2.8, and the Kilfitt Makro Kilar 90mm f2.8 at very reasonable prices.  Check your local community or flee market for used camera shows.  Here in Toronto, there are three to five of these shows every year so lots of opportunities to check out some lenses you want to buy.  I occasionally get some good deals on lenses from Pawnshops and second hand stores.  If you live in a small community, unfortunately, you only choice might be eBay.  Just remember, you don't have to buy all the lenses you want in one shot.  Finding one of the lenses you want after a long hunt is a thrill and that's part of the fun.  Make it fun, but don't get addicted.

What to look out for when buying manual focus lenses
First thing first - make sure it's functional.  Aperture clicks and stops down, focusing action is smooth without choppiness.  Aperture and focusing are two most important things to look for, because if these two things don't work, you either can't focus, or shoot wide open all the time, or both.

Other areas of concern is fungus.  Be sure to check carefully there is no fungal growth inside the lens.  Very minor ones, if the lens is cheap enough, can be tolerated, especially if the growth is at the corners.  The worse kind is the one growing in the rear elements.  Generally, avoid lenses with fungus as they will continue to grow and get worse.

Scratches on glass elements.  I am not as concern about this as other people.  I have had lenses which are very scratched up and they produce beautiful pictures.  Minor scratches do not affect the performance of the lens, but heavy and fine scratches all over the lens will soften the lens, and make it more prone to flare.  So, a few minor scratches are ok, and they tend to be cheaper.  Avoid heavy scratches at the rear elements, especially when they are in the middle.

Dust Specks/Haze.  It's unavoidable.  Old lenses are generally not very well sealed and thus dust will get inside more easily.  Again, don't panic when you see a few specks of dust inside. Practically ALL my lenses have some degree of dust problems.  However, haze is a big issue.  Basically it's a layer of very fine dust settled over a long time.  This haze will reduce contrast of the lens, and makes the lens flare easily.  Avoid lenses with haze.

Oil inside glass/Aperture blades.  In many preset type lenses, oil on blade is normal and should not be overly concerned about them.  Some of them have oil on purpose to lubricate the blades.  But for auto aperture type, oil in them is not normal.  Eventually, more will leak out and the aperture blades will stick together and you won't be able to stop down any more.  If you see oil on non-Preset type lenses, it's the first sign that the aperture may stick in the near future.

De-centering issues.  Many old lenses have this issue, especially those that were repaired or opened before.  Generally, the problem is that one side is sharp, but the other side is blurry.  This could also be caused by a cheap adapter, so be sure you know that the problem lies.

Adapters

Many asked what brand of adapters they should buy.  I really don't know.  Personally, I buy cheap Chinese made adapters and they have been working well for me.  Occasionally, I would buy a few good ones, like those from Fotodiox (pro-series), and Metabones.  High quality adapters can cost hundreds of dollars each.  If you  are just starting out, I suggest getting the cheap ones to try.  Unless you have some very expensive lenses, like a collection of Leica M-Mount lenses, it might make more sense to get a good adapter to share amount your lenses.  Even though I buy mostly cheap adapters, I have spent more than $2,000 on adapters so far, because I have so many different lens mounts.  They used to be very expensive, even for an M42-EOS adapter, until the Chinese started making and selling them.  Generally, common mounts like M42, Nikon, Olympus, etc, are very cheap, because demands are higher and they can sell at lower price but at greater quantities.  More obscure mounts like Alpa, DKL, etc, are far more expensive because there aren't that many lenses out there and therefore demand for them are much lower.

The major difference between cheap and expensive adapters are precision and accuracy.  Cheap adapters usually are not very accurate, and they tend to focus past infinity or not reaching infinity.  Cheap ones are also less precisely made where flatness of the adapter is not guaranteed, resulting in uneven sharpness in the pictures.  But, buying an expensive adapter does not guarantee it would work flawlessly with your lens.  I have one quite expensive and name brand Leica to EOS adapter which would not allow any of my Leica-R lenses to focus to infinity.  Be sure you can return the adapter if they don't perform as advertised.

Now that you have some knowledge of what lenses you can use, and what adapter to buy to get the lens to work on your digital camera.  The final question you might be pondering remains: Why bother with manual focus lenses?


Manual Focus Lenses - the good


Value for the money:
Most consumer lenses that come with the camera these days are not very good.  For one thing, they are slow, Often with a maximum aperture of f5.6 at the long end.  If you need to shoot at low light, you will have to folk out a few hundred dollars for a faster auto focus prime.  On the other hand, there are some great manual focus lenses costing under $40, such as the Takumar 55mm f1.8, which has better quality, in terms of build and optical, than the kit zoom you have.  Yes, it's not fair to compare a zoom to a prime, but if you want low light shooting lenses, there is no other choice.  If you have never used a large aperture lens before, you will be surprised to find how wonderful it is to be able to shoot shallow depth of field.


In Control:
I don't know about others, but I feel a sense of control when using manual focus lenses.  Let's face it, the cameras we have today basically does everything for us.  Auto exposure, auto focus, auto white balance, auto ISO, etc.  I sometimes feel that it's the camera doing all the decision for me.  With manual focus lenses, I control the aperture or shutter speed and focusing.  If you are using manual lenses for video, you will know the focusing on manual focus lenses are light years better than auto focus equivalent.

A satisfying experience:
The feeling after looking at a beautiful photograph taken with a cheap lens gives me immense satisfaction.  True, many manual focus lenses are not cheap, and can be more expensive than AF version, but majority of them are cheaper, especially the common ones.

Variety:
There are thousands of old lenses out there, most of them are cheap.  You can try many of them without breaking the bank, not to mention the different type of lenses like Cine lens, Lomo effect lenses (Lomo/Lensbabies), Telescopes, microscopes and much more.  All these the original manufacturers do not make. Different lenses give you distinctive looks to your pictures.

Manual Focus Lenses - the bad

No Automation:
With very few exceptions, adapting manual focus lenses on your digital camera means you will lose all the automated features.  There will be no auto focus, no auto aperture control, and in some cases, no metering (for some Nikon consumer DSLRs).

Quality of lenses not guaranteed:
Since most manual focus lenses are old, some are decades old. Even the best kept lenses might have minor issues after so many years of use. Most of them do not look like new (if that bothers you).  Some might have aperture issues, others have focusing problems, etc.  Read the section on "What to look out for when buying a manual focus lens".

Flare Easily:
Old lenses (even many new AF ones) flare easily, as the coating on them (some don't even have coatings) are not as effective as modern coatings.  This problem can be partially avoided by using lens hoods, or not shooting into the light source.

Exposure Variance:
This is only for the Canon DSLRs shooting through the view finder.  Live-view has no problem with this.  Basically, as you stop down the lens, the exposure tend to be less accurate.  My experience shows that some lenses need to be dialed -1 in exposure compensation for each f-stop you stop down.  EVIL camera shooters do not have this problem, as what you see in exposure is what you get.  You will learn to compensate in no time at all, so this is really not a problem.

A word about exotic lenses

Eventually, you will get tired of your garden variety of common lenses you have in your possession, and start looking at more exotic lenses.  Names that you may never have heard before, like Alpa, Dallmeyer, Kinoptik, Angenieux, Som Berthiot, Boyer, Cooke, Kern, Hugo Meyer, Astro Berlin etc, will start to enter your horizon.  These optical wonders are like drugs and can get very addictive and expensive.  Some of these lenses costs thousands of dollars.  Unless you have lots of disposable income, buying these kind of lenses will put a lot of pressure on your finances.  Sometimes it's hard not to think about them.  The first time I saw pictures from Kinoptik 50mm f2 and Dallmeyer Super-Six, I couldn't believe pictures can be rendered and look so beautifully! Make sure you understand that manual focus lenses is for fun and you don't need to spent thousands to enjoy them, unless you can.

This last installment will conclude our "Adapting Manual Focus Lenses on Your Digital Camera" series.  Thanks for reading.  If you have any questions, please e-mail or leave comments.

Adapting Manual Focus Lenses on Your Digital Camera - Part III

After some initial mumble jumble, we talked about adapting manual focus lenses on the Canon EOS EF mount in Part II.  As you can see, there are lots of options for Canon shooters, but also a lot of limitations, due mostly to the reflex mirror clearance.  In Part III, we will talk about using manual focus lenses on the Micro 4/3 and Sony E-Mount, and to some extend, the Fuji X-Mount (not the AX mount on their old SLRs).

Without doubt, mirrorless cameras, except the Samsung NX series, with a flange focal distances of 25.50mm, are the most adaptable cameras to use on manual focus lenses.  The Samsung's 25.50mm thickness was just enough to shut out the use of adapting Leica-M lenses, which many have said as one of the biggest disappointments.  Leica M lenses are considered the pinnacle of 35mm lenses.  The build and optical quality is unequaled in the 35mm lens world.

So, what lenses can be used on Micro 4/3 and E-Mount cameras?

In a word, pretty much all lenses existed on the 35mm format, if anyone is willing to make the adapter for a particular lens mount.  The very short flange focal distance of the M4/3 (19.25mm), E-Mount (18mm), Fuji X (17.70mm) provide the opportunity to use a wide range of optical lenses, 35mm format, medium format, C-mount cine lenses, enlarging lenses, projection lenses, etc.  The possibilities are practically endless.  The only question is: is a mount adapter available?

The most popular lenses to use on M4/3 and E-Mount are Leica Thread Mount (LTM), Leica M mount and C-Mount.  The reason is that these lenses have very short flange focal distance and therefore adapters can be made very thin.  Adapted lenses would look very small, to complement the small M4/3 and NEX cameras.  The quality of lenses are also some of the best in these mounts (except c-mount, where there is a big variance).  To compare, the M mount adapter for NEX is roughly 10mm for the NEX, whereas the M42 to NEX adapter is almost 30mm thick.  Even a pancake Contax 45mm f2.8 lens will look like a 85mm SMC Takumar when mounted on the NEX.  Take a look at the comparison pictures below:

Voigtlander 40mm f1.4 & Contax 45mm f2.8 Pancake compared with and without adapter.
 
On adapters: C-Mount Switar 50mm f1.4, M-Mount Voigtlander 40mm f1.4, QBM 50mm f1.8

As you can see, the mount makes a big different on how large the lens will look when mounted on the camera.  Even a normal, small 50mm f1.8 QBM lens will look huge when mounted on the NEX, but the C-Mount and M Mount lenses look nice and small.

A note on c-mount lenses.  There are so many different lenses on this mount with different sizes.  Be very careful what you are looking for in c-mount lenses.  Some will not cover the image circle of the NEX or even M4/3 sensor, and some are too large to be used and be able to focus to infinity.  Even those that mount and focus to infinity with full image circle coverage, the image quality may not be what you are looking for.  The allure of c-mount lenses are their cinematic quality, or quirky characteristics, or weird bokeh or some combination of these or more.  Make sure you know what you want.  Some of these lenses costs thousands of dollars!

Another benefit of short flange focal distance of these mounts, is that the traditionally macro-only use of the enlarging lenses and projection lenses can be used like a normal lens; that is, be able to focus to infinity.  I have done quite a bit with both the enlarging and projection lenses.  If you do a search on my blog, you will see many examples.

In our next and final installment, Part IV, we will talk about buying manual focus lenses, what to look out for, why some lenses costs thousands and others almost nobody wants at give away prices, and the costs of different adapters.
