Out of 5
Want a fantastic 55mm lens at f/2 and don’t mind manual focus then this lens is a bargain. I have found 3 different versions which are all optically different and some mechanically different but this is the newest and best version as expected.
The lens is a little soft at f/2 with a fair amount of chromatic aberration. If you don’t mind stopping it down a bit then this lens is very sharp and not too hard to find. The lens is tiny and feels great in the hands, handles really well and is simple to use.
