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 only 14cm from
edge of the lens, F 8. Focus on
the program wheel of the camera.
A very nice lens, wich
opens a tad wider than 2.8. Already at F 2.5 it's
quite good, only a little softness at the edges, but there is
vignetting which disappears completely when stopped down (and which
wasn't there on film as far as I remember). Stopped down it's fine in
opinion. It has good capabilities of close focussing. However it's
quite big and heavy.
