Canon 1100D vs SX420
The Canon EOS 1100D (called Canon T3 in some regions) and the Canon PowerShot SX420 IS are two digital cameras that were officially introduced, respectively, in February 2011 and January 2016. The 1100D is a DSLR, while the SX420 is a fixed lens compact. The cameras are based on an APS-C (1100D) and a 1/2.3-inch (SX420) sensor. The 1100D has a resolution of 12.2 megapixels, whereas the SX420 provides 19.9 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 1100D and the Canon PowerShot SX420 IS? 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 side-by-side display below illustrates the physical size and weight of the Canon 1100D and the Canon SX420. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
The SX420 can be obtained in two different colors (black, red), while the 1100D 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 SX420 is considerably smaller (45 percent) than the Canon 1100D. In this context, it is worth noting that neither the 1100D nor the SX420 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX420 has a lens built in, whereas the 1100D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 1100D and their specifications in the Canon EF Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 SX420 was launched at a lower price than the 1100D, despite having a lens built in. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 1100D features an APS-C sensor and the Canon SX420 a 1/2.3-inch sensor. The sensor area in the SX420 is 91 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 5.6. The sensor in the 1100D has a native 3:2 aspect ratio, while the one in the SX420 offers a 4:3 aspect.
Technology-wise, the SX420 uses a more advanced image processing engine (DIGIC 4+) than the 1100D (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the SX420 offers a higher resolution of 19.9 megapixels, compared with 12.2 MP of the 1100D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.19μm versus 5.15μm for the 1100D). However, it should be noted that the SX420 is much more recent (by 4 years and 10 months) than the 1100D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX420 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon SX420 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX420 for good quality output (200 dots per inch) amounts to 25.8 x 19.3 inches or 65.4 x 49.1 cm, for very good quality (250 dpi) 20.6 x 15.5 inches or 52.3 x 39.3 cm, and for excellent quality (300 dpi) 17.2 x 12.9 inches or 43.6 x 32.7 cm. The corresponding values for the Canon 1100D 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 Canon EOS 1100D has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Canon PowerShot SX420 IS are ISO 100 to ISO 1600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 1100D provides a higher frame rate than the SX420. It can shoot video footage at 720/30p, while the SX420 is limited to 720/25p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the 1100D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX420 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 1100D and Canon SX420 in connection with corresponding information for a sample of similar cameras.

Concerning the storage of imaging data, both the 1100D and the SX420 write their files to SDXC 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 1100D and Canon PowerShot SX420 IS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 1100D has a hotshoe, while the SX420 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The SX420 is a recent model that features in the current product line-up of Canon. In contrast, the 1100D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1100D was succeeded by the Canon 1200D. 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 how do things add up? Is the Canon 1100D better than the Canon SX420 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS 1100D:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (12 points each). 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 1100D and the Canon SX420 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom Camera listings 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 1100D or the SX420 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 expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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 above review scores should be interpreted 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
