Modern Photography tests Pentax 645 - 1985

I posted the scans of the test in
Guide to using a Pentax 645 - Modern Photo Test 1985

Scroll down a bit to where I have the scans...

SMC Pentax A 645 55mm f/2.8

They did a thorough job back then

Nice! I still have my 645, but it's been a few years since I used it.

Wow, it's amazing what is inside a camera and I tend to forget how complex of a machine they can be.

Thanks for the post. I often thought the 55mm A and 150mm f/3.5 were underrated, MP tests confirm.

Facinating look at the camera as well as the lens tests. Agreed, Modern Photography used to do very comprehesive and in my opinion accurate tests. I used to ry adn get a hold of lens test they would publish, especially on lenses I owned and then would test methodically to see how my tests matched up with theirs. It still amazes me how complex the camera the jeweled movements of a watch (or least seems so). Thanks ever so much for taking the time to do this...much appreciated!
