ISO revisited

I've had some pretty reasonable results from my camera at ISO 2000, considering it's not meant be a high ISO machine. Then again I've had rough looking grainy noise at lower ISO values like 500 or 720.

Here are two 100% sections of out of focus sky from shots taken (with the same lens) yesterday.

1/1000, 6.3, 2000

1/400, 6.3, 720

Go figure.
