I recently found a rather obscure lens, the Auto Ozunon 24mm f/3.5. I decided to put it to the test.



Considering the 42.4 mp sensor, I think the center resolution is pretty damn good at all the tested apertures.
There is quite a bit of vignetting. Personally this is not a problem for me. Corner performance is not great, but gets OK at around f/11.

Some more test shots:





A picture right into the sun. We see some reflections, but the overall contrast and colors remain good:




The lens allows for 1:4 reproduction, which is not bad at all:


I'm actually quite surprised by the overall image quality this lens is capable of.

Yes indeed. And sharpness seems to be only an issue in the very extreme corners.

I'd live with that, the center sharpness is impressive for a 24. Like 1 small

These old 24mms seem to be able to do pretty well. I have an Osawa 24mm f/2.8, quite sharp at the center.
