Ok I have a Canon Digital Rebel XT. It has a shutter life expectancy of 30,000 to 50,000 actuations. I have taken maybe 20,000 shots in the past year (I am very camera happy, and shoot 100+ photos daily). For Christmas, I have been offered (by my mom) a Canon 70-200 F/4 L, or trade in my XT and she'll pay the difference on a 30D.............. Now I know lenses are more important for better images, but I am asking this. Would it be smarter to buy the 30D for reliability, or the 20-200 f/4 for quality? Either one is an upgrade but IQ isn't the only factor here, it's a dual variable equation. what would you do? I'd hate to have my shutter die in 6 months, knowing that getting a 30D could extend it to 5 years........ but what's the use if I'm only shooting on a kit lens and a 50mm 1.8? Another option, that I'd have to do in hopes of beating the clock is to get the lens for Christmas, then saving my own money, try and gather up enough for a 30D before my XT dies.
