on the sample image (except closest focus) for full resolution. The
full resolution image opens in a new window, so you can keep it open for comparison. Focus is on the satellite
dish to the right of the big solar panel near the center of the photo.
Closest focus is 20cm from outermost edge of the lens, F 8. Focus on
the program wheel of the camera.
This lens is very small and very lightweight. However this one is not
really compatible with full frame sensors, there is heavy vignetting
(particularly on upper right edge, but also down left; this doesn't
disappear stopping down) and it has some colour cast. Without clear
blue skies the problems become less visible, a bit of cropping lets the
corners disappear and produces nice very wide images with a nostalgic
image impression. Carefully aligned there is nearly no distortion.
beautiful images on film with a Bessa L. It's nice with a Sony A6000.
There is a new version III of this lens, made for full frame sensors,
but the new one is much bigger and heavier, hence less attractive.
