What type of photography do you mainly work on? Landscape/portrait/wildlife etc?
Mainly Landscape, occasional and photography, and a bit of all-round general stuff. Bulk of this shot on Digital, Canon 7D, but a fair old bit on film with my EOS-3.
What is your favourite Canon lens that you've owned or used and why?
Hard to pin down a single lens - for the Landscape stuff, it'd probably be the 17-40L, works as a nice walkabout zoom on the digital, weathershielded (with a filter on the front at least) and makes a lovely wide angle zoom for the full-frame film camera.
For shooting bands, then it'd be the low-light loveliness of the 85mm 1.2L (mk i version) - it's slowish to focus, heavy, and wide open you struggle to get anything to fit in the plane of focus, but when you need that ability to shoot in a coal-cellar at night, little or nothing will beat it.
For the All-Round stuff, I have to say, I've been pleasantly surprised by the EF-S 15-85mm f3.5-5.6 IS USM that came as a kit-lens on the 7D - it's not particularly fast, it's not built to the L standard, though it's not the wobble-fest that typical kit-lenses seem to be, but it's a nice working range, focuses pretty quickly, and has pretty damned good all round IQ. If only it was a full-frame lens, it'd be a perfect all-rounder. So, If it's going to be an all-rounder for me - it's got to be full-frame, and i'm going for the EF 24-105mm f4L IS USM - it's the "normal" part of my f4 "holy trinity" - the 17-40,24-105 and 70-200.
What is the Canon lens that you've disliked the most and why?
EF28-80mm f/3.5-5.6 - old kit lens, that came with a EOS-5 film body I bought for spares. Nothing particularly bad about it in terms of image quality, but it sounded like a coffee-grinder when it focused. It's currently on long term loan to a friend, who's perfectly happy with it as it's light, decent IQ and most important, it was free!
