A7 and the lens.
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
dish to the right of the big solar panel near the center of the photo.
Closest focus is 55cm from
edge of the lens, F 8; it's not really close. Focus on
the program wheel of the camera.
This lens is very small
and very lightweight. Wide open, there are
shades on the upper edges (as with all very wide lenses) and it has
softness towards the edges. Carefully aligned there is no distortion.
It's a wonderful walk-around lens if you prefer wide angles. At F 8
focussing is very easy because of the wide depth-of-the-field range. It
produces nice very wide
images with a nostalgic
image impression. I like it quite well.
