Pink Tulips -- NEX-5 & Zoomar Makro Kilar 90mm f2.8 @ f2.8. Click to see larger.
If you like creamy, dreamy, delicious bokeh, the Makro Kilar 90mm f2.8 delivers. Of all the manual focus lenses I have used, this lens is by far my favourite when it comes to bokeh, and the Leica-R Summicron 90mm f2 is a close second. As I said before, the unique feature of this lens is the rings from highlights wide open. These rings are gone by

Admittedly, everyone looks at bokeh a bit differently. There is no bad/good bokeh. It's a very personal thing. Aside from the nice bokeh, I like the pictures from this lens too, due to its very rich tonal rendition. There are so much details that can be pulled from pictures taken with this lens. The highlights roll off very gracefully that you won't see the disgusting dead white when it clips.

My copy of the Makro Kilar is not great, and getting it was purely accidental. I was buying the Birns & Saywer 150mm f3 movie lens, and the seller said he had another lens at home and if was interested to see it. Sure I was, and I am glad I said yes. The condition of this lens is poor. Very well used and quite dusty inside, and the coating is starting to disintegrate. All that does not seem to affect the image quality one bit. I love how the images are rendered by this lens.
Sorry about all the tulip pictures. I like tulips :)
