I use a canon 700D, with a 18-55mm lens usually.Thanks for the pointers - may I ask what kind of camera you use? Oh and be careful of those buttons on the vest...I know he would have to be a contortionist to reach them while he's wearing it, but I hope he doesn't chew them if it's in his reach.
I generally don't leave him in sweaters when unsupervised as sometimes when he's lying down his paw slips out of the hole, and gets caught in the sweater, which leaves him walking around on 3 paws! But, I hadn't even thought about the buttons! Thanks for the reminder!
