Body comparison: Canon XTi vs SL1

The physical size and weight of the Canon XTi and the Canon SL1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The SL1 can be obtained in two different colors (black, white), while the XTi is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon XTi and the Canon SL1 are of equal size. However, the SL1 is markedly lighter (27 percent) than the XTi. In this context, it is worth noting that neither the XTi nor the SL1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the XTi gets 370 shots out of its NB-2LH battery, while the SL1 can take 380 images on a single charge of its LP-E12 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SL1 was launched at a markedly lower price (by 31 percent) than the XTi, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon XTi vs SL1

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the SL1 is 1 percent bigger. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the SL1 uses a more advanced image processing engine (DIGIC 5) than the XTi (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.

Canon XTi and Canon SL1 sensor measures

With 17.9MP, the SL1 offers a higher resolution than the XTi (10.1MP), but the SL1 has smaller individual pixels (pixel pitch of 4.31μm versus 5.71μm for the XTi). Yet, the SL1 is a much more recent model (by 6 years and 6 months) than the XTi, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The SL1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Canon EOS Rebel XTi has a native sensitivity range from ISO 100 to ISO 1600 The corresponding ISO settings for the Canon EOS Rebel SL1 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600..

Many modern cameras are not only capable of taking still images, but can also record movies. The SL1 indeed provides for movie recording, while the XTi does not. The highest resolution format that the SL1 can use is 1080/30p.

 

Feature comparison: Canon XTi vs SL1

Apart from body and sensor, cameras can and do differ across a variety of features. The XTi and the SL1 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the SL1 has a higher magnification than the one of the XTi (0.54x vs 0.49x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon XTi and Canon SL1 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The SL1 has a touchscreen, while the XTi has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The XTi writes its imaging data to Compact Flash cards, while the SL1 uses SDXC cards.

Both the XTi and the SL1 have been discontinued, but can regularly be found used on eBay. The XTi was replaced by the Canon Xsi, while the SL1 was followed by the Canon SL2. Further information on the two cameras, as well as related accessories, can be found on the official Canon website.


Review summary: Canon XTi vs SL1

So how do things add up? Is there a clear favorite between the Canon XTi and the Canon SL1? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS Rebel XTi:

  • More heavily discounted: Has been available for much longer (launched in August 2006).


Advantages of the Canon EOS Rebel SL1:

  • More detail: Has more megapixels (17.9 vs 10.1MP), which boosts linear resolution by 33%.
  • Better low-light sensitivity: Can shoot in dim conditions (0.3 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC II).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.49x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (4.9 vs 3 flaps/sec) to capture the decisive moment.
  • Less heavy: Has a lower weight (by 149g or 27 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
  • More modern: Reflects 6 years and 6 months of technical progress since the XTi launch.

If the count of individual advantages (bullet points above) is taken as a guide, the SL1 is the clear winner of the contest (13 : 1 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

XTi 01:13 SL1

Do the specifications of the Canon XTi and the Canon SL1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the XTi or the SL1 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews: Canon XTi vs SL1

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Notes: ++) highly recommended; +) recommended; o) reviewed; -) not available.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
