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 ;-)
