Also, are lenses cheaper in Canada and the States as I'm out there in August.
What do you mean? I've got one that has a fault linked to the zoom. At certain focal lengths the displayed aperture is f1, and when you take a picture, it doesn't stop down. It you were trying to use an aperture other than f4 that means underexposure in auto, overexposure in manual.
possibly slightly off topic so apologies in advance...the gf is selling a sigma 10-20mm (nikon fit) and wondered if anyone was looking for one atm? She bought it new and has hardly used it so wants rid. ste.
I've just got hold of a 10.5 fish which oddly enough is really wide and is making some interesting bouldering shots.
Composing well with ultra-wides isn't easy. Most of the shots I see would benefit from a tighter composition with a less extreme wide, but they instead it's usually rack out to 11 and bung everything in.
