Nice set of images Eric.
Thx.
Small birds are so hard to follow in woodland. The Sony struggled with the multitude of branches. Totally failed to capture a single image of the blackcap and chiffchaff that were flitting around.

Most of the bird shots were at 12,800iso….because I tried to move the exp comp wheel and mistakenly turned the shutter speed to 1/2500 and the auto iso did the rest! Although that speed was useful on the flitting birds I was expecting the high iso to be riddled with noise….but it wasn’t.
It makes me wonder if you get less noise per iso setting by using higher shutter speeds. o.O

I know it’s true that long exposures (>1sec) DO introduce more sensor noise but never considered that the reverse might apply when using high shutter speeds. I suppose it’s logical. It may also explain why sometimes I’ve been unhappy with noise levels on my bird shots. I have usually tried to keep iso down by using the slowest shutter speed I can get away with.  I feel a test coming on.:thumbs:
