My vintage K20D lately has developed some metering issue. Anyway I have just got a Pentax K70 few days ago and did some quickie trial/test shots with FA28mm F:2.8. These are respectively F:4, F:3.5 and F:2.8 wide open. I cannot afford a new K1 and have to settle with a more affordable hardware. Please look at the exif as I did not do any pp on the jpg out the camera. I never knew that my TV remote is so filthy at all until now LOL.
I did some high iso shots and they looked impressive too
