Hi, Ive been shooting with P&S cameras for years with good results, but Im looking to upgrade finally to an SLR. I am partial to Canon, only because Ive enjoyed their P&Ss for awhile, the latest being their G9 which I love (as long as I never go above 400 ISO). I almost never use the P&S in any automatic mode, and I generally keep it in manual or aperture priority. Ive also begun to get involved with HDR imaging. So, its time to upgrade for when I want better quality shots. The thing that has kept me from moving to an SLR is my desire for a full-frame camera because I love doing landscape shots, and because Im scared of losing any investment in lenses. I like the 40D, but I prefer the full-frame of the 5D (but not its price). If I purchase a 40D now, will the lenses work with a full-frame Canon in the future? This is essentially what I like shooting: - Landscapes (especially with HDRs ) (for work) - Home interiors (for work) - Some portraits - Low light shots and I dont like using flash - Some fast action shots of animals (for pleasure) I dont really understand SLR lenses all that well in terms of which size to get. From my p&s background, I use a 6x zoom. So, I think I would like an all around all-purpose lens at first, and then I would like to get a wide angle lens, followed by a good zoom. Can I get these with the 40D and have them be useful on a future Canon full-frame? Which lenses should I get? Are the L series lenses worth the price (I dont mind saving up and getting an L series if its really worth it AND itll work for my future DSLRs)? Lastly, Ive gone this long without a DSLR, so should I wait a little longer? Is a full-frame 40D on the horizon? I dont care if it has 15MP. I care more about low noise at high ISOs, higher dynamic ranges and not blowing $$ on lenses that might do me no good in 6 years. I would really appreciate any advice.
