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
satellite
dish to the right of the big solar panel near the center of the photo.
The Holga uncropped.
The lens in APS-C mode. There is still heavy vignetting.
Closest focus is 55cm from
outermost
edge of the lens. Focus on
the program wheel of the camera.
This is a cheap plastic lens. It doesn't cover full format, you have to
set your camera to APS-C mode. There is still heavy
vignetting at APS-C setting.
You can buy an E-mount version of the lens. There is no aperture
setting, it's fixed at F8. Infinity isn't at the infinity mark, but it
focusses to infinity nevertheless. It has a kind of "zone focussing",
focus is (too) stiff.
The plastic mount wobbles, but is light tight. It's a crappy lens with
"Holga Style" quality and results. You either love it or leave it. At
least, you have been warned. The results are very similar to Holga
cameras, so you can have the Holga fun without the expenses for film
and processing ;-)
