This camera is known in the USA as the Digital Rebel XSi. In some other parts of the world, it is known as the EOS 450D.
In 2003, Canon revolutionized the digital camera world by introducing the first under-$1000 digital SLR camera... the original Canon Digital Rebel. They improved on it in 2005 with the release of the Digital Rebel XT and again in 2006 with the XTi. In the Spring of 2008 they added a new top-of-the-line model to the Digital Rebel family... the Digital Rebel XSi.
This latest version of the Rebel offers 12.2 megapixel images, a larger
LCD screen on the back of the camera, and a whole bunch of other improvements over the XTi. I made the upgrade
from the XTi to the new XSi in May of 2008, and have been enjoying getting to know the new model. My favorite new
feature is the ability to set the iso to automatic. It doesn't sound like a very big improvement... until
you actually start using the camera, and then you find out what a great idea that auto-iso feature really is! If
you have much experience with SLR cameras, you know about the relationship between shutter speed, aperture, and the iso
setting. If you choose a high shutter speed and a low iso setting, your lens may not be able to open the aperture
wide enough to let enough light in to get the shot. Or, if you choose a small aperture setting and a low iso
setting, the camera may go to such a slow shutter speed that your photos will be blurry. The solution to both
problems is auto-iso. Pick a shutter speed or pick an aperture setting, and let the camera choose the other two
settings automatically. Let me give you a real world example...
Canon Digital Rebel XSi with 100-400mm "L" series lens attached
Let's say you're using a big zoom lens on your camera... such as one of my favorite lenses, the 100-400mm "L"
series zoom. If you use a slow shutter speed with a long lens like that, the long lens amplifies all the shakiness
in your hands and you end up with blurry pictures. So, it's a good idea to lock your shutter speed at a fairly
quick setting when you use a long zoom lens. It's also a good idea to use a fast shutter speed when shooting
things that move quickly, like kids or animals. I wanted to take a picture of one of our Cocker Spaniels, and in
order to achieve a "blurry background" effect I used my 100-400mm lens. To heighten the effect, and to ensure a
crisp picture of the dog even if she moved a bit, I set the shutter speed to 1/400th of a second. Rather than
fiddle with aperture and iso settings until I fumbled on the right combination... I just let the camera take care
of those for me... and this photo is what I ended up with:
Reese, one of our American Cocker Spaniels
With the shutter speed set to 1/400th of a second and the iso setting in
automatic,
the camera chose ISO 640 and an aperture of f/5.0... which resulted in a
perfect photo.
Absolutely no third-party noise reduction was used on any of the photos on this page!
This brings up another important point about the Digital Rebel XSi: it does a fantastic job of taking pictures at high iso settings without adding a lot of noise to the pictures or sacrificing a lot of image detail. This was something that always impressed me about the XTi, too... great picture quality at high iso settings. What's really surprising is that even though the XSi has a higher resolution imaging device, it has even less high-iso noise than the XTi. If you know much about digital camera imaging devices, you know that if everything else is equal, you usually get more noise in a more detailed image. So, it took some great engineering to go from a 10 megapixel imager in the XTi to a 12 megapixel imager in the XSi and not end up with more noise or less detail. Bravo to the Canon engineers!
Of course, some things have remained the same in all of Canon's Digital Rebel cameras... they are compatible with the full line of Canon EF and EF-S lenses. Other standard Rebel features: the ability to shoot in "RAW" mode, which gives you the ability to make much higher quality adjustments to your photos than you can when working with .jpg images... a full range of shutter, sensitivity, and exposure adjustments... and there's an intelligent flash "hot shoe" on the top of the camera. I had a camera a few years ago that featured a cheap stripped-down hot-shoe. Canon's system is so much better! The camera and the external flash talk to each other and share exposure, shutter, focus, and white-balance information. It really makes for the best quality flash photos I've ever been able to take. Also, if you get the 580EX external flash, you have the ability to add a second less-expensive flash unit later, which you can place in another part of the room and the two flashes will fire together at the same time. My friend, Carol Patterson, a professional photographer, showed me how this works one time and it was so impressive!

I already mentioned that the Digital Rebel XSi is a 12 megapixel camera... but maybe I should really spell it out for you: The XSi shoots images that are 4272 pixels wide and 2848 pixels tall. That may sound like a lot... it may even sound like overkill... but in my experience, it can definitely come in handy. Let me give you an example. Here's a photo that I shot with my Digital Rebel XSi at a charity fun-run/walk:
Original version of the photo - not cropped
I was excited when I got home and saw how this photo turned out, because I had caught some great body language from one of my friends and her son... but I was zoomed out way too far at the time I snapped the photo. I was able to improve the photo quite a bit with some cropping:
The problem with cropping, of course, is that you throw away a lot of resolution. The original was 4272 pixels by 2848 pixels (12 megapixels)... but by the time I was finished cropping it I was down to 1714 pixels by 1233 pixels (2 megapixels). I was able to print out a borderless 8.5x11" print of the cropped version of the photo, and it still looked very good since at 1714 x 1233 pixels I still had enough resolution to print at 150 dpi. In other words, the original image from my Digital Rebel XSi had so much resolution that I was able to throw away 83% of that resolution in the cropping process and still have enough resolution left over to make a good print of the photo! It's impressive!
I've been extremely impressed with the Canon Digital Rebel cameras. I've taken some great photographs! I had already owned six previous digital cameras when I decided to upgrade to the Rebel XSi, and it's been interesting to see how each camera has been better than the others.
There are lots of good reasons to go with a digital SLR camera over a
traditional point-and-shoot digital camera. Without question, the end result... picture quality... is
superior on photos taken with a digital SLR camera. It's great to be able to use interchangeable lenses...
so you can use the right lens for the particular shot you are trying to get. As someone who tends to upgrade
hardware frequently... it's nice to know that the Canon lenses I buy today will work with the Canon digital SLR
cameras of the future. I don't think it's unreasonable for me to believe that I'll be using some of the lenses I
have right now for the rest of my life. The best reason, though, is probably the reduction in "shutter lag" in
digital SLR cameras. Anyone who's used a regular digital camera knows what I'm talking about... when
you push the button, you want the camera to take the picture NOW! Also, if you put a good lens on a digital SLR
camera, you'll find the autofocus feature works better than on any camera you've ever used before.
All this comes at a price, of course. Digital SLR cameras are a lot more expensive than point-and-shoot cameras... but the results speak for themselves. As someone who really loves photography, I think it's worth the money. The prices have definitely come down over the last few years, too.

One of the great things about using a digital SLR camera versus a point-and-shoot is the hot-shoe which allows you to use an external flash unit. Most inexpensive digital cameras do not have a hot-shoe, so you're stuck with only the built-in flash. But when you get in to the world of digital SLR cameras, you have a hot shoe so you have the option of adding an external flash on to the top. You will find that you are able to get much better results in many situations where you are shooting indoors... especially if the room has a white ceiling you can bounce the flash off of. I use a Canon Speedlite 580EX external flash on my camera, and it makes all the difference in the world in the quality of my indoor photographs. The Rebel XSi is great at high iso photography, which means that in a lot of cases you can shoot indoors in natural light. But, this only really works well if the light in the room is very evenly distributed. In the real world, you tend to have very uneven lighting with a lot of shadows. So, a flash is quite helpful. If you just use the built-in flash, though, you get very strong un-natural looking light. You can get a much more natural looking soft lighting effect by using an external flash and not pointing it directly at the subject... you swivel it up towards the ceiling and let the light bounce off the ceiling and fill the room. This is called "bounce flash". If you're going to buy an external flash, make sure it can swivel! Some lower-priced external flashes can not. And make sure it can swivel both vertically AND horizontally, so you can bounce it off the ceiling regardless of whether you are shooting in portrait or landscape orientation! The Canon Speedlite 580EX is a good match for any Canon camera that can accept an external flash, and will swivel in both directions. |

Here's a demonstration of why an external flash is so useful.
Three photos of our neighbor, Natalie, using different lighting techniques:

The one taken with natural light is not bad at all... there was a fair amount of light coming in through a window. The one using the built-in flash is horrible... the lighting is very harsh. You can see it actually made her squint. But the best photo of all is the one using the Speedlite 580EX bounced off of the ceiling. Look at the difference in the way her face is lit in that photo. If you're going for the best possible indoor photos, the Speedlite is worth every penny!
Ready for another suggestion regarding accessories for the Digital Rebel?
My favorite accessory for the camera is the battery grip. It's great for several
reasons. First off, it holds two Canon batteries at the same time... so you can go twice as long without
having to worry about running out of batteries. Unless you are shooting thousands of pictures at one time, you
never need to worry about whether you've got enough battery charge left when you have the battery grip attached to your
camera.
Second, the battery grip features an extra set of camera controls that are oriented for vertical (portrait mode) shooting. Without the battery grip, when you rotate the camera to shoot in portrait mode, it's very awkward to reach the shutter release, for example. With the battery grip attached, the shutter release on the battery grip is in the perfect spot. It's also easier to hold the camera in portrait mode when the battery grip is attached. Finally, the camera just looks bigger and more professional with the battery grip attached. If you put the battery grip and a big zoom lens on your Digital Rebel, people may ask you what newspaper you work for!
The picture on the right is a Rebel XTi mounted on a battery grip. I don't actually
have a picture of an XSi on a battery grip yet... but it looks very similar.

| Finally, don't forget that Canon does not include a memory card in the box with the Digital Rebel. So, you'll need to be sure to get one... otherwise you won't be able to take any photos with your new camera! Each jpg image shot with the Rebel requires about 4 megabytes of memory space, and each RAW image takes up about 15 meg... so I think a 2 gigabyte card (or larger) is what you should start with. If you're going to shoot in RAW mode a lot, think about a 4 gig CF card. |
