Hi everyone.
A couple of months ago I had the opportunity to get a 600mm L IS USM at a very good price. I've taken it out a few times but I'm struggling to get sharp images with it. I know it's a professional lens and I'm not a professional, but I thought I'd be getting more keepers than what I've been managing.
I recently went up to my sisters in Wales and took the following images, some with and without a converter. All shots were roughly 20 feet away.
I used a gitzo tripod with IS on. I've tried to keep the shutterspeed as high as possible to account for shake, but the weather wasn't the best meaning a high ISO on my 7D.
I've not adjusted any shots and they are all uncropped.
Am I right in thinking I should have been stopping down for the TC shots?
It's been suggested the lens might need micro adjusting, but I'm not confident doing this.
