10 Reasons To Buy a DSLR
Kurtis writes, "If you're planning on getting a digital camera for yourself this holiday season, here's 10 reasons why you should choose a Digital Single Lens Reflex camera instead of a point-'n'-shoot. DSLR cameras are obviously not perfect for everyone. This article also has a couple of small blurbs about who shouldn't buy a DSLR, and a few things that could be deemed negative aspects of DSLR cameras."
I'm a total amateur, but I've fallen in love with photography thanks to the XT. I've not used a 30D, but I can't imagine that it would present *that* much benefit to a person brand new to photography... I can set everything I need to set on my XT within a second or two. Generally I let it do its own metering and either select aperture or shutter speed, this works very well for me, especially as I'm still learning what combinations yield what results - I'm generally much happier with a shot that's exposed properly so I can see what mistakes I've made, rather than getting something pitch dark or entirely washed out and basically having to throw it away. Still, I can set mode, ISO, speed/aperture very quickly, often without looking. It'd be nice if I had a dial for ISO rather than having to go through the menu but as long as you remember what ISO you're currently on, it's not tough to set it by feel (and you can probably tell by the resulting change in light metering). I'm sure for a pro more speed/flexibility might be desirable, but for hobbyists I would totally agree with the lens comment. I can sell/give away my XT in a few years when I start getting frustrated with the controls (if that ever really happens), and upgrade to the next step up at 20 megapixels or whatever is current.
For Canon, I would strongly recommend the 50mm f/1.8, it's under 100 bucks and will let you take most indoor shots without a flash. It is extremely easy to use and will let you get used to a prime lens. The autofocus is slow and noisy, but it gets the job done. Another great lens I've had experience with is the 28-135 IS - it's got an image stabilizer which isn't quite as useful as I had hoped, but it's a very good range of zoom for typical walkabout photography, it's not too hefty, and the image quality is quite good in my admittedly uncultured opinion! You can get the new XTi, both of these lenses and still walk away paying less than getting a 30D with no lens at all. The XT kit lens isn't horrible either, it lets you get down to 18mm for 100 bucks... I'm not sure if there are that many options that wide without either being fish-eyes or over 700 bucks.
A couple provisos - getting into the DSLR habit is like getting into musical instruments, car tuning, or home theater, or high end PC gaming. You're going to get addicted to it and start spending absurd amounts of money (if you're not careful). "Good" (L) Canon lenses start in the neighborhood of 1000 bucks. I haven't bought into that level yet, because I know it'd be throwing my money away at my current skill level. However, like good musical instruments, the stuff you buy has the potential to last a very long time, and from what I've read the Canon EF lens series has been going strong for quite a while now. But you're still pouring money into what will some day be obsolete technology, or worse, something you're not interested in anymore. Secondly, when you get "serious" about it, you look like a total nerd. I still feel very very awkward carrying a camera bag around - but if you're going to do anything useful with your camera you just about have to. Even without the bag, the camera is very obtrusive in the best of times, with small lens on. If you're reading this far into a comment on Slashdot, you probably don't care, but hey, fair warning. =) In the long run, I will probably buy a point and shoot so I can have something I can stick in my pocket and take places I wouldn't feel comfortable/interested in lugging my real camera around to. Once you start the hobby, you really start thinking about photographing everything interesting you see, in my experience.
Oh, and the other thing that sorta bites about the whole hobby is vendor lock-in. Your camera vendor is your lens vendor is your accessory vendor. There are cheaper knock-off lenses, but in general, the higher quality stuff is single vendor. If you're interested in Canon, or if you're a DSLR initiate like myself, I've found this page to be very, very useful:
