Canon SX40 vs T100
The Canon PowerShot SX40 HS and the Canon EOS Rebel T100 (labelled Canon 4000D in some countries) are two digital cameras that were revealed to the public, respectively, in September 2011 and February 2018. The SX40 is a fixed lens compact, while the T100 is a DSLR. The cameras are based on a 1/2.3-inch (SX40) and an APS-C (T100) sensor. The SX40 has a resolution of 12 megapixels, whereas the T100 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 PowerShot SX40 HS and the Canon EOS Rebel T100? 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 SX40 and the Canon T100 is provided in the side-by-side display below. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T100 is notably larger (16 percent) than the Canon SX40. In this context, it is worth noting that neither the SX40 nor the T100 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX40 has a lens built in, whereas the T100 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 T100 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon SX40 features a 1/2.3-inch sensor and the Canon T100 an APS-C sensor. The sensor area in the T100 is 1086 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.6. The sensor in the SX40 has a native 4:3 aspect ratio, while the one in the T100 offers a 3:2 aspect.
With 17.9MP, the T100 offers a higher resolution than the SX40 (12MP), but the T100 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.53μm for the SX40) due to its larger sensor. Moreover, the T100 is a much more recent model (by 6 years and 5 months) than the SX40, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the SX40 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon T100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T100 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 SX40 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Canon PowerShot SX40 HS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Canon EOS Rebel T100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 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 T100 provides a faster frame rate than the SX40. It can shoot movie footage at 1080/30p, while the SX40 is limited to 1080/24p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the SX40 has an electronic viewfinder (202k dots), while the T100 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Canon SX40 and Canon T100 in connection with corresponding information for a sample of similar cameras.

Concerning the storage of imaging data, both the SX40 and the T100 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 PowerShot SX40 HS and Canon EOS Rebel T100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T100 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the SX40 does not provide wifi capability.
The T100 is a recent model that features in the current product line-up of Canon. In contrast, the SX40 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the SX40 was succeeded by the Canon SX50. 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 there a clear favorite between the Canon SX40 and the Canon T100? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon PowerShot SX40 HS:

If the count of relative strengths (bullet points above) is taken as a measure, the T100 is the clear winner of the contest (14 : 8 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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.
How about other alternatives? Do the specifications of the Canon SX40 and the Canon T100 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the SX40 and the T100 in practical situations. 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 following table reports the overall ratings of the cameras as published by some of the major camera 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
