Lens Review Date: August 26, 2013 I can recommend this lens: Yes | Price: None indicated | Rating: 9 

Pros: very sharp at middle apertures, build quality, cheap, manual focus only
Cons: no auto/man switch, manual focus only
Sharpness: 9    Aberrations: 8    Bokeh: 8    Handling: 10    Value: 10   

Both photos taken with a K-01 ISO 1600, 1/20 f/2.8

Mine is the single coated version without the "-M" in the name. I bought it on a Yashica TL Electro-X in the summer of 1973. I glued the auto pin down with JB Weld.

The lens is a bit soft wide open nice and sharp by f/2.8 sharpest at f/5.6 and f/8, and declines due to diffraction after that.

I can see a little bit of Chromatic Aberration at the corners when wide open.

In the first photo you can see flare. This was a very low light situation, and there were (relatively) bright points just outside the frame.

Lens Review Date: July 31, 2013 I can recommend this lens: Yes | Price: None indicated | Rating: 9 

Pros: Solid construction, very sharp with reduced aperture, excellent colors
Cons: No A/M switch, boring bokeh
Sharpness: 10    Aberrations: 10    Bokeh: 3    Handling: 9    Value: 10   

My copy of this lens has amazing color rendition and is extremely sharp, especially when stopped down to f/8. I could not see aberrations in my stopped down shots. The control rings are well sized, easy to grab, and operate very well. Aperture starts at f/1.7 and the next step down is f/2. This step is marked with a tiny dot next to f/1.7 and is very a short click. You would almost miss it if you didn't know about it.

There is no A/M switch to control the aperture so you will need to glue down the aperture pin or modify the internals of the lens. I glued my pin down after debating it in my head. My bokeh turns out boring, especially compared to a Helios 44M.

I am very pleased with this lens as a walk around lens where I would want as much sharpness across the picture as possible.

I got this lens in a kit full of other goodies so no price is given for my review.

Enjoy the pixel peeping below!
