Hej,
Is it speed ? Or ISO 400 noise reduction blurring the details ?

Speed or ISO? A590 has a bit of noise at Iso 400 + speed (max) still not high fast enough for freezing wing motion. So I think it's a bit of both. Wind on the camera................possible but I dont think so.

Hej,
Just test ISO 100 and 1/500s, and ISO 200 and 1/1000s.

#46........Camera was set at ISO 80 - shutter 1/1000 (max in manual mode). Lot of motion blur in the bird. That was the reason for increasing the ISO in #49 ( to obtain higher shutter speed) . At 400 ISO, noise level high, requiring use of 'Noise Removal' software resulting in softening of the image.
The original was cropped by 50%.
Thanks for your constructive comments.

Hej,
Okej, then you can't really do anything about it :/
I'm surprised 1/1000s can't freeze those.

yvesson -

I have A540 so your approach is very interesting to me (and i wish i had seen all this before fall set in and the birds flew south). some questions:

which script are you using now?

how far away do place the camera from the shooting area? Do you use AF?

do you have standard settings that you set manually?

Hej,
I use fudgey script now, I set macro but auto AF, slow mode (so it adjust AF before the shoot).
The distance between bird and cam is very small, between 10 and 30 cm usually (thus macro mode needed).

I now use 3s burst mode too.

The script setting are kinda the default ones, I just change to : "chroma channel", "slow mode", "3s burst" and between 20 and 30 threshold.
My cam is in Av mode always, so I just get the fastest speed for the available light.

Winter is also good for the birds which don't migrate : you can feed them and get a nice spot easily.
