Nowadays I mainly shoot on digital, my DSLRs being a Canon EOS 5D plus an EOS 40D. The 40D allows me shoot extreme telephoto yet preserve most of the resolution of the 5D which I prefer for shooting wider angle.

My main telephotos are a Canon 100-400 IS USM L, plus a 70-200 f4 IS USM L which has an excellent image stablizer and is very light and compact. For everyday use I have a Canon 24-105 f4 IS USM L which spends most of it's time attached to the 5D.

For ultra wideangle photography I have a Sigma 12-24 EX DG, plus a Canon 17-40 USM L which I use for wingmount photography as it does not change shape when focusing or zooming. This is adventageous because the lens is not going to be upset by slipstream effects.
