f/1.7 | f/2 | f/2.8 | f/3.5 | f/4 | f/8

f/1.7 | f/2 | f/2.8 | f/3.5 | f/4 | f/8


Corner - Wide Open

Corner at f/1.7

f/1.7 A bit soft but still sharp for being wide open. The image looks soft because there is a bit of coma, a little chromatic aberration and quite a bit of spherical aberration causing low contrast.
f/2 Sharpens up a bit with more contrast but still holds onto chromatic aberration and a lot less spherical aberration.
f/2.8: Very sharp with fantastic contrast and only a little chromatic aberration.
f/3.5: Sharper yet with almost no chromatic aberration.
f/4: Sharper yet.
f/8: Sharper yet.


There is quite a bit of vignetting at f/1.7 and slowly starts to clear at f/2 and quickly clears at f/2.8 with only a hint at f/3.5.

The blur is pretty good and only a little distracting.


100% Crop



Has quite a bit of Barrel Distortion and more then usual for a 50mm.

Chinon has a few really well built lenses that feel great, are simple to use, all metal and built like tanks; and this is one of them. There are a few versions of the Chinon 50mm f/1.7 and some are plastic and cheaply built.

This is a really nice and sharp lens but suffers from a fair bit of coma and spherical aberration when shot wide open. It causes the image to be hazed. The chromatic aberration sticks around for a while but isn’t too bad. In low light situations this lens would perform really well and is worth grabbing if you can find one for a good deal.
