Want a fantastic 55mm lens at f/2 and don’t mind manual focus then this lens is a bargain. 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, fantastic, and is not too hard to find. One thing you need to watch out for is that the elements can turn a yellow tinge over time but this is really easy to get rid of just by simply shining a UV light in it for a little while.

The lens is tiny and feels great in the hands, handles really well and is simple to use.
