Lens Review Date: March 17, 2016 I can recommend this lens: Yes | Price: $2,550.00 | Rating: 9 

 
Pros: Sharp, contrast, tripod mount
Cons: Hint of chromatic aberration
Sharpness: 10    Aberrations: 9    Bokeh: 10    Handling: 10    Value: 10    Camera Used: Pentax 645D   

Having sold the older A version of this lens about a year ago I have missed it. After a recent purchase of a x1.4 rear converter and using it on a 67 200m lens I had the feeling that I did not have the best.
I have run a few tests shots today with the FA 300mm and the lens absolutely matches the glory of the older manual focus version. The x1.4 converter does little to detract from image quality. Contrast is maintained as is sharpness. There is a loss of a stop or two. The results are far superior to using this converter on the shorter 67 lens.
I was prepared to pay the extra for the newer auto-focus model of this lens as it would preserve re-sale value and the newer lens has a TRIPOD MOUNT which is a BIG must in such a large piece of glass.

The following images are taken with this lens. Some are with the x1.4 rear converter and for comparison there is one image shot with the Pentax 67 200mm with rear x1.4 converter on the 645D (with adapter)

Lens Review Date: September 1, 2009 I can recommend this lens: Yes | Price: N/A | Rating: 9 

 
Pros: My sharpest 300
Cons:

Excellent lens.
I have not use any manual focus 300mm 645 lens so I am really comparing this to the 350 and 250 Sonnars.

When I semi retire I decide to stick with Pentax as my 35mm/Dslr and I still have to find another 300mm that is better.

This lens along with the 120Macro dispel the myth that 120 camera lens are inferior to 35mm counterparts because of the larger chromes makes up for any shortcoming.
