I needed to revive this thread with new info for the Pentax K-1
I was browsing thru the 1678 photos I had taken at the Rogers Cup IN montreal 3 weeks ago... and I am really impressed on the IQ of the combo Pentax K-1 and SMC Pentax-DA* 300mm f4 ED [IF] SDM was able to render in the image.
For example, have a close look at this photo of Denis Shapovalov doing a serve.
It was shot in relatively low light conditions, and from the 3rd level in the Uniprix Stadium (I was maybe 100 meters from the subject).

Now, have a look at the next photo I published. It is a 1:1 crop (696 x696 pixels ) of the tennis ball, where we can clearly see the text "
Penn ATP 3" and some bristly hairs around the tennis ball.

Please also note that this was shot wide-open at
ƒ/4, 1/
800s and
3200 ISO, and that this photo is direct from the camera body (RAW),
no PP at all!.
