300 mm FA 5.6

french · 02-24-2018, 12:03 PM

Hello

I have a 300 mm pentax FA 5.6. The focus is not good and I have to make micro-settings. I have the impression of a slight lack of sharpness for the moment
Do you have experience of this lens?

Do you mean the FA*400 mm f5.6, or the FA*300 mm f4.5?

I realized it was a medium format lens from the thread title. I wanted to clarify since it it might help to know the lens/body for fine af adjustments. I'm no expert on these however.
