Great Macros...Poor medium to long range Autofocus,
This review is from: Canon Digital Rebel XSi 12.2 MP Digital SLR Camera with EF-S 18-55mm f/3.5-5.6 IS Lens - Black (Camera)
I picked up this camera two weeks ago at a local store. Overall, it's a solid camera. Color reproduction is wonderful, it's quick, low noise with high iso, and terrific macros. The camera is blazing fast. Please refer to the other posters for the good points of this camera.
Now i'll discuss the shortcomings. The major one, which has been referenced to in various forums such as dpreview and a few online review sites is poor AutoFocus. Not all cameras are affected, but mine was. If you shoot at an object from w/in 10 ft, it has trouble over 50% of the time picking up the autofocus point and often selects the wrong point. If you use center focus, it gets pretty close but final image is still a bit blurry. It becomes a bit sharper w/ the live view autofocus system. When I took some outdoor pics of some animals, i couldn't quite lock on what i was interested in. Even when taking shots of people outside w/ a prominent background, it seems to have trouble deciding if it wants to focus on the person or the background. I'd say that 20% of my shots were actually in focus and those look wonderful. The remaining ones had the focus off. So i'm gonna send my camera to canon for repair. I went to best buy and tried out a 40D and the focus was rock solid. If you get a good camera, kodus to u.

I hope it was only that camera that you have because I'm about to get one...

I appreciate your comments- I am almost on the verge of buying this camera- lI love Canon, but will rethink the Xsi because of the focusing problem- which would really bother me if i ended up with one that only worked 20% of the time. I was actually in a store today looking at one and was having trouble with the auto focus! Thank you for the tip!

One of the most useful things I learned about the Canon AF is that it uses contrast to focus. If you take a picture of a white wall or a piece of paper with no lines or sources of contrast, it won't be able to focus. But if there is a line or other source of contrast, then it can focus. So keep that in mind when it has trouble focusing, try centering on a slightly different area that has contrasting lines/colors/shading instead.

Hmmm are you sure this is a camera issue and not a lens issue? It sounds like you know what you're talking about though so hopefully not too many of them have this problem! I have one on the way and I'm hoping for the best.

The Auto Focus feature is built into the lens; is it not? Wouldn't this be a lens problem and not a 'camera' problem. Did you use the 18-55mm f/3.5-5.6 lens? If so, this is a lower end lens. If that is the problem, can't I buy just the camera body and upgrade to a better lens which will fix the problem?

Everyone, don't be so quick to blame it on user error. Do a Google search and you will find a growing number of posts with this same issue and even some well documented cases with pictures comparing the XSI to the original digital rebel (300D).
Here is an online review complaining about the auto focus for what it is worth: http://www.dcresource.com/reviews/canon/e
"I should also point out that I had some generalized focusing problems with the camera. The first camera I tested produced an unusual number of out-of-focus shots, with multiple lenses. I received a replacement camera and while it performed better, I still saw the occasional out-of-focus photos. I could never really nail down the cause of the problem, and it wasn't something I could replicate. If you end up with a XSi that seems a bit "off" in the focusing department, it may be worth swapping it for another one."
Here are some more..
You can also do a search on the Canon rebel forum on dpreview.com and you find countless posts about the auto focus issue: http://forums.dpreview.com/forums/forum.a

What type of lens were you using? Standard lenses might have problems focusing in that short of a distance. my rebel II (film) has the same problem. If you're focusing on something that close, you might be better off getting a wide-angle lens, which are designed for shooting at closer distances. That might help with the focusing problems. Focusing on the image is programming built into the camera, but the camera translates what images are being viewed through the lens.

The macro capabilities have not much to do with the camera. What lens are you using?
The auto focus varies also a lot depending on the lens and the lighting conditions.

I've had mine since last November with nary a problem as far as autofocusing goes. It's a great camera.

I got my XSi in August 2008 and have not had any AF problems at all.
