I have loved photography nearly as long as I can remember. However, when it came time to choose a career I did not believe I could make enough money with photography so I went into software development. I still did a lot of photography as a hobby even winning a contest on the former Compuserve photo forums. However, a few years ago I became so busy in my career I felt like photography was distracting me from my job so I set my camera gear aside. This was just at the time when DSLRs were starting to come on big. So today, I find that I want to get back into photography and even try to make some money on the side but I want to get new gear. My previous camera was an EOS A2e with a couple of Canon lenses. But I have a lot of catching up to do on digital photo technology.
I've been reading the spirited thread on the new EOS 7D and have learned quite a bit. I had previously had my eye on the 5D Mk II mostly because I wanted the full-frame viewfinder. I hadn't realized there were two different sizes of sensors used by Canon. I had only been aware of the varying number of pixels per sensor. So now I know about full-size sensors and the APS-C sensors and that EF lenses are best for the ful-size sensor while the EF-S lenses are best for APS-C sensors. (Can you mount an EF lense to a camera body with an APS-C sensor or an EF-S lense to a camera body with a full-size sensor?)
Furthermore, some of the comments in the thread makes it sound like Nikon has been a more forward thinking company as of late and that Canon is playing catch up. This makes me wonder if I should consider Nikon. One reason I may want to stay with Canon is because I already have a couple of Canon lenses (EF 100-300 f4.5-5.6 and EF 28-105 . Given that they are made for use with film, they would work best with a full-size sensor. But, is the mount the same? Can I use them with a 5D Mk II?
Should I care about full-frame vs APS-C? I'll likely be doing mostly landscape and wildlife as well as some portrait photography. I appreciate comments and suggestions.
Thanks,
Darwin
