This is one of these rare 3rd party gems I am on the hunt for! This lens is extremely good with amazing bokeh blur making it a very valuable portrait lens. When you pick this lens up you would think it is cheap and junky because it is so light. When you tap the lens it actually sounds hollow! I was blown away with how great this lens is. It competes pretty well with the Takumar 135mm f/2.5 and even the Canon 135mm f/2 L!

Mechanically the lens is well built, but feels very cheap. This lens takes T2 mounts which is very nice for putting it on almost anything.

Two things that are a little annoying about the lens is that this lens is not an automatic diaphragm so you have to use the annoying Open Close slider. Also the closest focus is 7ft or 2.2 meters so if you need a close focusing lens this is not it. However this gets plenty close for most subjects.

Optically this lens suffers from a bit of chromatic aberration but this can be limited a little in post processing. The lens is very sharp at all stops with great contrast and really nice color. There is very low, if any, distortion and the best feature of all is the really great bokeh.

If you find one grab it! This lens is actually worth hunting down as well if you can find one for a good price.
