Originally posted by Kerrowdown Great club, and maybe will help inspire us to use these unsung heroes more often. I have:
1. Pentax-M 200mm f 4.0, great lens for zoo visits and high school music performances in the gymnasium, sharp and clear, using on K-3 for narrower FOV.
2. Pentax 645 (A and FA), not the sharpest Pentax medium format lens, but good for tight portraiture.
3. Mamiya 210mm f 4.0, nice and sharp for use on 135 format, does not adapt to medium format because of incompatible registry distances, and on K-1 and K-3, exhibits much narrower FOV, more like 300-400mm FOV.
4. Pentax 67, f 4.0, sharp, sharp, marvellous rendering on either Pentax 645, Pentax full-frame, or APS-C, FOV good for portraiture on 645N/D/Z but really too tight for portraiture on full frame or APS-C but great for birding especially using 2X rear converter.
I will start looking for opportunities to use these unsung heroes a bit more often!
