Question: Rebel XT vs XTi Is it worth paying almost an extra $200 to get the XTi?  I'm debating whether to get the Rebel XT or XTi, and really can't decide...
Document: This is a really nice Digital SLR, but if you are upgrading from the original Digital Rebel be warned that this is a MUCH smaller body. It does not have the same high quality feel as the first and it is actually pretty hard to use if you have large hands. To me it is almost worth paying the $450 more for the 20d just to get the larger body.
I was struggling with the decision to buy the Canon S3 vs. the Rebel XT for several weeks. I ended up returning the S3 to buy the Rebel XT and I'm very happy with it. Many people compare the S3 with this SLR model, but the optical quality is a world apart. Because of physics, you simply cannot get the same quality with the S3 zoom lens that covers the entire range. The Rebel XT snaps the pictures almost immediately when you press the shutter button.
But should I try something as simple as pointing it at one of the small furry creatures living here too, it generally won't (auto-) focus. And you can't focus it otherwise, really, because you can't tell through the viewfinder or LCD whether it's truly focused, as compared to viewing it on your computer. FINALLY with the XT Rebel I can point it, hold down the snapshot button halfway, and get an instant autofocus. It's like The Terminator locking in on whatever you're pointing at.
This is probably the best non-breathing thing I have. I absolutely love this thing!!! To be frank I did not compare with Nikon counterparts or other Canon cameras, I also have never used another SLR before so I went with what most reviews said about the XT. Almost bought the XTi but price difference at the time was $200. Plus I love the information screen on these cameras and dont mind the small LCD screen.
You will still come out cheaper than if you buy the XT with a kit lens AND have an amazing, fast lens that gets raving reviews on Amazon and elsewhere. Check the lens reviews for yourself, especially if you're not familiar with prime vs. zoom lenses. The tiny remote is handy too!I'm betting you will eventually buy at least one more lens than what you start with to explore the capabilities of the XT. This is true whether you start out with the kit or the 1.8.
I love my Rebel XT. I have had it for 3 years. It takes really good pictures, whether it is pictures of my family or nature photography. Any problems I've had with photo quality have been due to user error. (I'm still learning the proper way to use all of the camera settings--it's taken me a while due to laziness, not difficulty.
I do suggest getting a decent polarizer and uv haze filter as they do help to produce more vibrant images outdoors.I had to choose between the XT and the XTi with the higher price tag. I have to say that other than the sensor cleaner and 2 extra megapixels(which you really don't need for most shoots) there's not much better about the XTi, you even lose the back lit settings display screen and only have the lcd.
I waited a while after purchasing this camera before posting a review, as I wanted to make sure I'd gotten to know it. Well, 9 years and almost 200,000 exposures into using it, I'm just about convinced. I've been trying for the last few years to kill it or let it get stolen, as I'd REALLY like to get a new camera. Alas, despite my best efforts, it refuses to die.
I bought this camera about a week ago to replace my film-based Rebel G. My previous digital experience was with a 2MP Canon Powershot S100. I'm not a professional photographer, but I really like taking photographs (vs. snapshots).
The camera's also got a pretty good battery life, but it wouldn't hurt to get a backup. If you're an amateur or hobby photographer who wants to upgrade to a DSLR camera, you should definitely consider this camera. Sure, the Rebel XTi model is out now, but this one is much cheaper, and it produces photographs that are almost  on par with the XTi.
Answer: I'm no expert, but during my research on the same question I found the following:1)	The difference between The 8MP on the XT and 10MP on the XTi is virtually undetectable until you attempt very large prints. At standard sharp resolution (300 DPI) even a 7.2 MP camera will give you an excellent 8X10 print. You really need 12MP over an 8MP camera to see results in smaller prints. Unless you think you'll print larger than 12X16, your eye likely won't detect any difference in quality between the XT and XTi. 2)	The XTi has more Megapixels on the same sensor - this can add more noise at higher ISO settings and from my research it seems the XT may actually take a sharper picture in many cases. But for your own opinion - here is a head to head XTi  - TX picture comparison:  http://www.dimagemaker.com/article.php?articleID=7323)	Opinions on the noise levels of the XTi vary, here is a good conversation on the subject,  some here own both XT and XTi: http://forums.dpreview.com/forums/read.asp?forum=1031&message;=205480884)	The XTI's dust cleaning system is as yet unproven - meaning that many owners of the XTi (professional and otherwise) are not exactly convinced the dust removal feature does what its supposed to.Over all, I found that some people were rather irritated with Canon - theorizing that Canon simply put out an XTi 10-mega pixel model with a few bells and whistles to compete with the other manufacturers. In effect, canon created technologically superior camera that may take inferior photographs.  The XTi is an excellent camera, but perhaps not a clear upgrade over the XT. On the upside, the XTi does have a bigger LCD screen and a 9-point auto focus. The XT has a 7-point system that some say can have issues auto focusing with faster lenses. Those faster lenses are typically very expensive and professional grade so the majority of amateur / semi-pro XT users have no complaints.  After my research, I went with the XT. Hope this helps
