Holy smokes! Who needs the DA560 @ $7000 ? Thanks Barondla and the rest of you for enlightening me
Pentax 550mm prime = DFA100WR + Q
I found with this combo, focus is critical as the 100 can show purple fringing if focus is not dead on. Images need clarity and a bit of sharpen adjustment.
I used one click of stop down on the Fotodiox adapter, not sure what the exact resulting f-stop is but figured it seemed to give the best results.
The Tele-wide viewer helps as a centered object is in frame.
Used 2 sec delay on a lightweight tripod and ballhead, forgot to turn off SR but I think it is disabled anyway.
Pentax 1650mm Prime = DA*300 + Q
This is the ticket for long range shots, as already proven by others.
The DA*300 is such a perfect lens for this setup, its controlled behavior makes it easy to focus and has no bad tendencies for CA.
I used minimal clarity and sharpen adjustments.
The Tele-wide is useless here, it is blocked by the hood of the 300. Will need to look into a red dot setup.
Can't wait to get out and try these in the field, I am pumped!
