The 200mm feels all loose and about to fall apart, but I've managed to get many good shots out of it. The 135mm doesn't have as much flaring and washing out problems as the 200mm, it's sharp and contrasty but with a lot of color fringing.<br /><br />I love your blog, keep it up :DAlfonsonoreply@blogger.comtag:blogger.com,1999:blog-4577546745078520453.post-66236040482289138902013-02-07T20:47:20.070-05:002013-02-07T20:47:20.070-05:00f-stop is simply a ratio of the diameter of the ap...f-stop is simply a ratio of the diameter of the aperture and the focal length. Thats why to know you need to grasp transmission as the real factor. When you see more elements its going to mean less transmission.obakesanhttps://www.blogger.com/profile/13743339737847465926noreply@blogger.comtag:blogger.com,1999:blog-4577546745078520453.post-17705305693204785392013-02-06T09:15:33.031-05:002013-02-06T09:15:33.031-05:00That's interesting.

I also have the FD 200mm f4, which is quite a decent lens.

When I c...Hi, I think you missed an importan point. When I compared the FD 200f4 to the OEM Panasonic 45-200 I found that it was much brighter at the rated f-stop (which was 5.6 so that both lenses could be compared at the same F). The FD200f4 gave me nearly 2 stops more light at the sensor than the zoom did.<br /><br />This is due to transmission losses in the glass. This is also the reason that professional cinematography lenses are rated in T-Stops not simply F-stops because inconsistencies in exposure due to lense chances are unacceptable in motion picture.<br /><br />obakesanhttps://www.blogger.com/profile/13743339737847465926noreply@blogger.comtag:blogger.com,1999:blog-4577546745078520453.post-37649594546534071182013-02-05T14:04:35.619-05:002013-02-05T14:04:35.619-05:00Yup.
