Dr Harout,
A few samples.
In Japan quite a lot of shots were big crops, often as much as 6000px down to 2500px due to subject distance. Luckily the A99 and 70-400G gave great sharpness and detail PROVIDED I managed to keep the camera steady. Adjusting in LR to medium contrast and making sure I used the full white to black range helped. The first shot was quite hazy, could have done with "dehaze" a few months ago!
approx. 4200px wide 1/1250, f7.1, ISO250, 330mm
approx. 2700px wide 1/500, f7.1, ISO200, 400mm
approx. 2800px wide (A77 plus 70-400G) 1/400s, f9, ISO100, 400mm (600mm) and still a big crop. Needed 1/400 to reduce shake, I'd normally use 1/125-1/200 to give more rotor blur at shorter focal lengths. many adjacent frames were scrapped due to blur. Probably got 1 out of 10 pin sharp.
At times I wonder if the new Sigma or Tamron 150-600 would be any use but I'm sure I'd suffer from increased shake at 600mm on both A99 and A77.
Hope these are of interest.
Mike
