I did and I was impressed - nice shots. However, they are small images so any noise and grain is minimised. I'd be interested to see a 100% zoom on parts of the hand holding the snail, it would be inevitably grainy with noisy colour spots I am sure at that ISO. This would be the case with 90% of all DSLRs so I am not knocking the Sony, equally, until I had the Sony I was unaware of just how impressive the noise control on the 5D was - virtually grain and noise free to 1600. It's a trade off I suppose.
