I was at Werribee Zoo photographing lion cubs with the wrong lens (the 300 GM is too long for lion cubs romping nearby) when I saw some wild birds soaring in the distance - snapped a shot, and they looked like raptors - I like raptors. One came closer, and I grabbed a long burst at 30fps.
This is cropped from one of the closest frames. It's not a good shot. I should have had the 2x teleconverter attached. I should have switched to spot exposure metering or turned up exposure compensation. I know (some of!) the things I had wrong, but I hadn't set out to shoot birds against an overcast sky. What I got was a black bird against a near white sky. The entire burst was in sharp focus, despite the bird being quite small in the frame almost the entire time.
Shot on the A9 III with the 300 GM wide open at f/2.8, ISO 250, 1/12800 (lot of light from that overcast sky).
So with those disclaimers, let me explain the bad things I did to the image (after capturing it badly).
I loaded it into Adobe Camera RAW, and boosted the exposure by a whole stop. I cut Whites by 10, Highlights by 40, boosted Blacks by 40, and Shadows by 70 (just eyeballing the results). To exacerbate my crimes, I then cropped it to a square roughly 1500 pixels on a side (from 6000x4000) - this is just over 2megapixels - a savage crop.
No de-noise, no output sharpening.
What you are seeing below is 100% - makes it obvious that the images from the A9 III completely fall apart when you boost the exposure like that, then crop the heck out of the image, right? And of course the A9 III is a terrible camera for birding - that's what several people on DPReview have said (strangely, none of them have used the camera...)
What do you think?
I'm pretty sure this is a black kite - they are native to the area. This image motivates me to visit some of prime birding sites in Werribee (not far from the zoo, in fact). I might even catch some GOOD shots of these birds! Might haul along the A1 + 200-600 as well as the A9 III + 300 + 2x.
