Canon 450D vs T4i
The Canon EOS 450D (called Canon XSi in some regions) and the Canon EOS Rebel T4i (labelled Canon 650D in some countries) are two digital cameras that were officially introduced, respectively, in January 2008 and June 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 450D has a resolution of 12.2 megapixels, whereas the T4i provides 17.9 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 450D and the Canon EOS Rebel T4i? 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.
An illustration of the physical size and weight of the Canon 450D and the Canon T4i is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T4i is notably larger (5 percent) than the Canon 450D. Moreover, the T4i is markedly heavier (10 percent) than the 450D. In this context, it is worth noting that neither the 450D nor the T4i 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 450D was somewhat cheaper (by 6 percent) than the T4i at launch, but both cameras fall into the same price category. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 T4i 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 T4i 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 T4i offers a higher resolution than the 450D (12.2MP), but the T4i has smaller individual pixels (pixel pitch of 4.31μm versus 5.19μm for the 450D). Yet, the T4i is a much more recent model (by 4 years and 4 months) than the 450D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon T4i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T4i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon 450D are 21.4 x 14.2 inches or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inches or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.1 cm for excellent quality prints.
The T4i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 450D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS Rebel T4i are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 cannot only take still pictures, but also record videos. The T4i indeed provides for movie recording, while the 450D does not. The highest resolution format that the T4i can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The 450D and the T4i 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 450D has a higher magnification than the one of the T4i (0.54x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 450D and Canon T4i in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T4i has a touchscreen, while the 450D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The T4i has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 450D does not have a selfie-screen.
The 450D writes its imaging data to SDHC cards, while the T4i uses SDXC cards. The T4i 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 450D and Canon EOS Rebel T4i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 450D and the T4i have been discontinued, but can regularly be found used on eBay. The 450D was replaced by the Canon 500D, while the T4i was followed by the Canon T5i. 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? Which of the two cameras – the Canon 450D or the Canon T4i – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 450D:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.53x).
- Longer lasting: Can take more shots (500 versus 440) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in January 2008).
Advantages of the Canon EOS Rebel T4i:
- More detail: Has more megapixels (17.9 vs 12.2MP), which boosts linear resolution by 21%.
- Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 3).
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- 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).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (5 vs 3.5 flaps/sec) to capture the decisive moment.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 4 years and 4 months of technical progress since the 450D launch.
If the count of relative strengths (bullet points above) is taken as a measure, the T4i is the clear winner of the contest (11 : 3 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 450D or the T4i. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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 above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
