I am looking to digital from my Canon Elan 7. Thinking about the Canon Rebel XTi. Any pros or cons?
There has been very little critical or negative feedback from users who have been with Canon and have switched from a film 35mm SLR to a Canon EOS dSLR camera including the Rebel line.
I have a Canon 20 D. I switched from a Canon Rebel G to the 20D about 2 years ago. I still occasionally use the Rebel because I like film. Anyway, advantages; interchangeable lenses and accessories. I use the same lenses, the same flash, as I used on the film camera. Yes there is the multiplication issue because the lenses are not "digital" lenses but it has never been a problem. Also, no film processing. Everything is done on the computer. You can print them yourself or go to a photo lab and have them printed. Of course the cost is an issue but I look at it as an invest. My 20D has paid for itself in the cost of film processing several times over in the last two years.
Be aware though, there is a learning curve to using and taking good digital photos. The basics are pretty much the same, but exposure is critical, and don't try pointing a digital camera toward the sun like you can with a film camera. But you lesrn quickly and get up to speed.
Drawbacks? Frankly I can't think of any. I know a lot of pro photographers who use the Digital rebel and are very happy with it.
