I now have a couple of these E Series lenses and they give outstandingly good image quality on my Nex and M43 cameras. I have yet to test any manual focus lens on the Fujifilm X camera as the 2 native zooms I have for it (the 18-55 kit zoom and the 55-200 tele zoom) are so good I don't feel the need for any more lenses or experimentation.

However, since the new Alpha cameras from Sony have no real native lenses available for them (at the time of this post) I have to experiment somewhat with manual focus lenses. I must admit also, I'm so taken by the pure pleasure I get from using all types of manual lenses, it's actually the reason I purchased the Sony cameras. The problem now of course is finding lenses that behave on these new full frame sensors. 35mm or shorter is going to be a problem with rangefinder lenses and I have a couple of those but we're not restricted to those rangefinder lenses, there are a multitude of SLR lenses that we can use.

I have some Nikon, Olympus and Pentax lenses that were class leading at the time they were manufactured and they perform very well on APS-C or M43 sensors but that doesn't mean the same performance can be achieved on a full frame sensor. I'll be testing quite a number of lenses in the near future to weed out those that don't perform well, and keep those that perform well for my landscaping escapades. I'll let you know how I get on.
