It comes with its plusses and minuses: on the pro side, it allows you to immediately see how the image turned out when it displays the photo on the LCD. If you're new to black and white photography, this can be a real benefit to help you improve your composition when taking photos in black and white. The con here is that when you take photos in black and white, the camera isn't capturing ANY color information. If you decide at a later date that a black and white photo would have been better in color, there's no way to retrieve the color.

This just means that when you set the XSi's Picture Style to Monochrome, you had better be certain that color is not the most compelling part of your subject. For those of you who'd like a little color in your images, the XSi lets you adjust the Monochrome Picture Style to "tint" your images:. If you're making the move from film SLR to digital SLR and are a black and white enthusiast, then you'll already be aware that there are LENS filters that can alter the tones in your black and white images.

For example, if your enjoy taking portraits with a Sepia tone and Green filter, then you can set this as User Picture Style 1. For dramatic landscapes, you may opt for a Blue tone and Red filter, which you can set as User Picture Style 2.

Once set, it's easy to select your custom Picture Style with the press of one button on the back of the camera so you can change back and forth as often as you like without having to dig through a lot of menus. This is due to the ever-increasing number of cameras from other manufacturers including Olympus , Pentax and Sony that include image stabilization in the camera body. Older Canon Digital Rebels do not include an IS lens - while it's easy enough to purchase the camera body and an IS lens separately, this will ultimately cost more than the XSi with its kit lens.

While taking some sample photos for this Rebel XSi guide, I decided to put the stabilization system through its paces. The trick to any image stabilization system is that it should help you take clear photos of non-moving subjects even when using very slow shutter speeds. The issue here is this: when the camera's shutter stays open for a long time, even the VERY slight motion of the camera in your hands can be perceived as motion.

This motion becomes evident in your photos as blur. These example should help to lend a little context to my next statement: I was able to get clear photos with the XSi's image stabilized lens set to 18mm even with the shutter open for one full second sample below. The following table shows a typical shutter speed scale. I've indicated the shutter speed that you can safely use without stabilization in orange italics, and the shutter speed that you're able to use with lens stabilization in bold this assumes the lens focal length is 18mm or wide angle.

The real benefit of all these slow shutter speeds is that you can take photos in low available light with the camera in your hands and still expect to get plenty of clear shots. This is why this feature is of real use to travel photographers who enjoy taking photos inside buildings where flash is not allowed. With dim natural light, no tripod and your flash disabled, the only way you're going to capture any photos worth keeping is by leveraging the IS system in the lens.

The kit lens that comes with the Rebel XSi has a fairly standard zoom range between 18mm wide angle and 55mm telephoto. This makes it a good lens for landscape and portrait photography, but not so good if you want to take photos of your subjects from a distance i.

I do have one small gripe about this lens and this is a common issue with Canon lenses — it doesn't include a lens hood. A lens hood connects to the front of the lens and "shades" the lens from direct sunlight. This prevents lens flares when you're taking photos in the direction of the sun. Despite my best efforts to keep the lens pointed away from the sun, you can still see the flare in the final image. This could have easily been avoided with the inclusion of a lens hood - something you can get for this mm lens but for an additional cost.

A lens hood is pretty standard issue these days with consumer SLRs, and if you check out cameras from other manufacturers like Olympus, Pentax and Sony you'll find that every kit lens includes a lens hood. It would have been quite simple - and cheap - for Canon to include a lens hood with this kit lens and not having it can impact the quality of your images of you take a lot of photos in direct sunlight.

The speedy and accurate autofocus system is paried with one-touch feature buttons for ISO, white balance, metereing, etc. While Canon seemed to skimp on the kit lens for the Rebel xTi, the image stabilized kit lens included with the XSi captures images that are clear, vibrant and colorful but the inclusion of a petal lens hood would have been a nice addition. This camera should be fairly high on your list if your photographic passion is any one of the following: travel, portraits, low-light or spontaneous.

You not only get a camera that is compatible with a huge number of Canon and third party accessories, you also get an SLR from one of the most popular line of digital SLRs available today. As is true with many other digital SLR cameras, buying the camera and lens is just the tip of the iceberg. There are a wide variety of additional accessories that can be paired with the Canon XSi that will expand and enhance what you can do with the camera.

The first thing that you're going to need for your Canon XSi is a decent size memory card, since no memory card comes packaged with the camera unless you buy a special combination kit that includes one. While it doesn't look like all that much the first time you see it, this tiny lightweight battery holds a charge for an incredibly long time. Despite the amount of use I put the Rebel XSi through for this guide, the battery charge never seemed to run out.

It finally did, but only after I'd racked up photos, with extensive use of the LCD screen a battery drainer in live view mode, to review photos and when changing settings using menus which I do quite often. As if this weren't enough, you can get even more time with your Rebel XSi between charges if you opt for the BG-E5 battery grip.

With the grip in place you can use two of the standard LP-E5 batteries, or you can also opt to power the camera with six AA batteries - good news for those who like to travel in remote locations where a standard power outlet for recharging the LP-E5 is not always available.

Almost all the buttons lie under your right hand, and each feels slightly different so that you can grope them without looking. None require two-handed operation: when you push the button to change ISO, white balance, metering, and so on, the menu persists while you navigate the options. For more on the camera design, click through to the slide show.

The biggest operational advantage the XSi offers over competitors is My Menu, which it inherits from older models. With My Menu you can build a go-to list of the most frequently accessed menu settings--in my case, for instance, Format and Live View settings.

However, the menus can be, irritatingly, a bit inconsistent and sometimes dumb. For instance, you can change ISO sensitivity with either the dial or the navigation buttons, but can only navigate metering choices via the nav. Also, in some cases when you have two columns to navigate, as with Picture Style settings, it doesn't let you move to the right or left.

It requires you to move all the way down the first column to get to the settings in the second column. The latter wouldn't be much of a standout if Nikon hadn't dropped to three-area AF in the D The camera also includes the same Highlight Tone Priority mode found in the 1D Mark III, which helps preserve detail in the brightest portion of a scene. Also, the XSi includes Canon's Auto Lighting Optimizer, which automatically adjusts contrast and brightness in case the image you captured isn't quite perfect.

While tested frame rate bounced around considerably after a steady initial burst of 16 shots — falling below 2 fps on occasion — I was thoroughly impressed that the camera was able to dash off those first 16 frames in exactly 4 seconds, for a better-than-advertised burst shooting speed of around 4 fps.

All in all, the XSi is blessed with a quick, responsive feel that makes it easy to live with for day to day shooting and proficient enough to serve as a budget primary or back-up body for light- to moderate-duty sports shooting. The XTi inherited its nine-point auto focus system from the then-current EOS 30D — a system which was then largely carried over with only slight revisions into the current advanced amateur model, the 40D.

With a fast-aperture USM lens, the setup is pure gold. The XSi was a bit shady at times when left to choose its own focus points, tending to miss foreground subjects more than I might have liked. Live view opens up a whole other range of options where auto focus is concerned. The system disables AF in live view altogether by default, but custom function settings allow the XSi to use either traditional focus-sensor AF in which the mirror must be moved out of the way for the camera to focus, thereby interrupting the on-screen preview for around a second in most cases , or use a slower contrast-detection focusing system like those found on compact cameras which allows the camera to auto focus without interrupting the on-screen preview, but often takes three to four seconds to lock.

Of course, you can always manually focus in live view, and Canon has conveniently provided 5x and 10x area magnification options to aid in getting everything sharply locked. Flash output can be compensated up or down up to 2 EV, with coverage out to around 17mm. The XSi was able to recycle a full-power flash discharge in under 3 seconds with a fully charged battery. Mode options are the four basic ones: auto, forced on, forced off, and red-eye reduction.

There are no preset slow sync or rear curtain flash modes, though the XSi automatically employs slow sync in the Night Portrait scene mode. On-board flash performance was, as before, perfectly acceptable, with spot-on exposure across a range of situations. Red-eye reduction also worked as anticipated, with a pre-flash effectively controlling unusual reflectivity.

Image stabilization is selectable via a dedicated switch on the lens, and there are no mode options for IS: rather, the system engages when the shutter release is half-pressed. My only gripe with the IS system as implemented, in fact, has to do with the noise it makes: whenever IS is enabled and engaged on the kit zoom, the system on our test unit emits a soft but clearly audible high-pitched shrieking noise.

While the issue may be traceable to an unusual lens copy, a similar issue was recently reported an apparently corrected through a firmware update with the 40D and some lenses, so perhaps a fix is on the way. Canon claims that the XSi is capable of taking shots on a single charge of its mAh lithium-ion battery. Admittedly, I used both flash and live view quite sparingly, but it would seem the XSi remains a competent performer where low power consumption is concerned.

An optional battery grip is available for the new Rebel, allowing the XSi to draw on a pair of lithium-ion packs or with an adapter six AA batteries. For shooters with older Rebels looking to upgrade to the XSi, however, note that the battery grip is a different unit than was used previously — the new camera is not compatible with older grips. If anything, the obvious weak link in initial testing of our full-kit review unit proved to be not surprisingly on the optics side of the equation.

The addition of IS is a nice, thoughtful improvement, but otherwise the new mm kit lens can hardly be seen as a step forward, in terms of optics or build quality, over the old one. Even stopped down, the lens is soft and lacks much punch, making landscape shooting somewhat unrewarding.
