New To Me lens - Pentax-A 645 45mm

ynnek · 08-21-2022, 12:33 PM

Anyone have any examples? How do you guys like this lens? This is a good addition to my kit. I now have the original P645, 45mm, 75mm, 120mm Macro, and 200mm. I would like to replace the 200 with an 80-160mm, which I had at one time and sold with another kit. Looking back, although it is a heavy lens, I really liked its versatility.

I didn't have the A45, but the FA. Got rid of it. The 45's are generally considered the weakest of the primes in the 645 family. Pity, dead useful FL. Both the 28-45 and 45-85 zooms exceed it in IQ. Not great when a zoom exceeds the IQ of a prime....

Magnification of the lower part of the image above shot @ f/9 : sharp edge-to-edge.

Good resistance to flaring and ghosting.

Starting last year, I decided to spoil myself with more modern auto-focus 645 FA lenses. First I got an FA 33-55 mm f/4.5 which proved to be a JEWEL of a lens. Then I got a new DFA 55 mm f/2.8 last Fall, another awesome performer. Two months ago I bought an FA 35 mm f/3.5 wide-angle that has proven to be a winner too. I'm 70 and my vision has started to deteriorate, so auto-focus lenses are well appreciated but I must say ALL 645 lenses perform like champions on my 645Z.

Thanks for the input. I have some 220 film I will test drive it with.
