Sample pictures: You may click
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 30cm from
edge of the lens, F 8. Focus on
the program wheel of the camera.
A very nice lens, even wide open. At F 3.8 there is just a hint of
shaded edges and it's a bit soft, but gets much better when stopped down. Carefully aligned there
is virtually no distortion.
