These lenses are full plastic
lenes from the Diana camera.
There is an adapter available for several camera mounts to use the
lenses of the Diana camera on small format digital cameras. I chose the
Canon adapter for this test. There is no aperture on the adapter. The
Diana camera has 3 apertures, F11, F16 and F22. The hole in
the adapter seems to be bigger than F11. So the lenses are too
soft.

for comparison. Focus is on the
satellite
dish to the right of the big solar panel near the center of the photo.
Lens doesn't focus well, too soft, colour cast and distortion. Seems to
be a bit longer than 20mm.

super wide angle on the Diana medium format, a moderate wide-angle on
FF.

Lens is marketed as soft
lens for the Diana. Doesn't focus at all, blurry, colour cast. Seems to
be longer than 110mm.
Maybe
I will make an adapter with apertures later. The adapter insn't well
made, most of the lenses don't focus to infinity, on the Diana they are
o.k. As is, the adapter is mostly useless, you only can make blurry
pictures with it. The 55mm and the 75mm however could be used for
dreamy portraits, they are sharp in the center and soften towards the
edges. There are expensive lenses for sale which do the same effect,
with this adapter you can have it for nearly nothing.
