Canon 100D vs 450D
The Canon EOS 100D (called Canon SL1 in some regions) and the Canon EOS 450D (labelled Canon XSi in some countries) are two digital cameras that were announced, respectively, in March 2013 and January 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 100D has a resolution of 17.9 megapixels, whereas the 450D provides 12.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 100D and the Canon EOS 450D? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The physical size and weight of the Canon 100D and the Canon 450D 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 100D can be obtained in two different colors (black, white), while the 450D 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 450D is notably larger (19 percent) than the Canon 100D. Moreover, the 450D is markedly heavier (29 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the 450D 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 100D was launched at a markedly lower price (by 31 percent) than the 450D, 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.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 450D is 1 percent smaller. 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.
In terms of chip-set technology, the 100D uses a more advanced image processing engine (DIGIC 5) than the 450D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.
With 17.9MP, the 100D offers a higher resolution than the 450D (12.2MP), but the 100D has smaller individual pixels (pixel pitch of 4.31μm versus 5.19μm for the 450D). However, the 100D is a much more recent model (by 5 years and 1 month) than the 450D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 100D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 100D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inch or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inch or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inch or 43.9 x 29.3 cm. The corresponding values for the Canon 450D are 21.4 x 14.2 inch or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inch or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inch or 36.2 x 24.1 cm for excellent quality prints.
The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 100D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon EOS 450D are ISO 100 to ISO 1600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The 100D indeed provides movie recording capabilities, while the 450D does not. The highest resolution format that the 100D can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 100D and the 450D 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%), as well as the same magnification (0.54x). The adjacent table lists some of the other core features of the Canon 100D and Canon 450D 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 100D has a touchscreen, while the 450D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The 100D writes its imaging data to SDXC cards, while the 450D uses SDHC cards. The 100D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 450D cannot take advantage of Ultra High Speed SD cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 100D and Canon EOS 450D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 100D and the 450D have been discontinued, but can regularly be found used on eBay. The 450D was replaced by the Canon 500D, while the 100D was followed by the Canon 200D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is the Canon 100D better than the Canon 450D or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS 100D:
- More detail: Offers more megapixels (17.9 vs 12.2MP) with a 21% higher linear resolution.
- Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 3).
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster burst: Shoots at higher frequency (4.9 vs 3.5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (117x91mm vs 129x98mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 117g or 22 percent) and hence easier to carry around.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
- More modern: Reflects 5 years and 1 month of technical progress since the 450D launch.
Arguments in favor of the Canon EOS 450D:
- Longer lasting: Gets more shots (500 versus 380) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in January 2008).
If the number of relative strengths (bullet points above) is taken as a guide, the 100D is the clear winner of the match-up (12 : 2 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon 100D and the Canon 450D place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 100D or the 450D 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.
This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.
The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
