Last week, I was given back my 13-year old 6mpx Canon 300D, the camera that got me started on digital photography. I posted a few close-ups of ducks which are quite acceptable http://www.canonrumors.com/forum/index.php?topic=33475.msg686994#msg686994
I thought I'd give it a try under more challenging conditions. Here is a chaffinch on a feeder, at iso800 through an EF-S 55-250mm. It took NIK software to clean up the noise, and it isn't sharp. Maybe upgrading to 5DIV was worthwhile? Mind you, it's fun using the old gear, and it gives good snaps.
