Canon 750D vs SX420
The Canon EOS 750D (called Canon T6i in some regions) and the Canon PowerShot SX420 IS are two digital cameras that were announced, respectively, in February 2015 and January 2016. The 750D is a DSLR, while the SX420 is a fixed lens compact. The cameras are based on an APS-C (750D) and a 1/2.3-inch (SX420) sensor. The 750D has a resolution of 24 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 750D 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 750D and the Canon SX420. 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.
The SX420 can be obtained in two different colors (black, red), while the 750D 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 (46 percent) than the Canon 750D. In this context, it is worth noting that neither the 750D 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 750D 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 750D 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The SX420 was launched at a lower price than the 750D, despite having a lens built in. 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 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 750D features an APS-C sensor and the Canon SX420 a 1/2.3-inch sensor. The sensor area in the SX420 is 92 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 750D has a native 3:2 aspect ratio, while the one in the SX420 offers a 4:3 aspect.
In terms of chip-set technology, the 750D uses a more advanced image processing engine (DIGIC 6) than the SX420 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the 750D offers a higher resolution than the SX420 (19.9MP), but the 750D nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.19μm for the SX420) due to its larger sensor. However, the SX420 is a somewhat more recent model (by 10 months) than the 750D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. 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 750D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 750D for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon SX420 are 25.8 x 19.3 inches or 65.4 x 49.1 cm for good quality, 20.6 x 15.5 inches or 52.3 x 39.3 cm for very good quality, and 17.2 x 12.9 inches or 43.6 x 32.7 cm for excellent quality prints.
The 750D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 750D 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 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 750D provides a higher video resolution than the SX420. It can shoot video footage at 1080/30p, 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 750D 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 adjacent table lists some of the other core features of the Canon 750D and Canon SX420 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 750D has a touchscreen, while the SX420 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The 750D has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the SX420 does not have a selfie-screen.
Concerning the storage of imaging data, both the 750D and the SX420 write their files to SDXC cards. The 750D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX420 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 750D 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 750D has a hotshoe, while the SX420 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the 750D and the SX420 have been discontinued, but can regularly be found used on eBay. The 750D was replaced by the Canon 800D, while the SX420 was followed by the Canon SX430. 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 is the bottom line? Which of the two cameras – the Canon 750D or the Canon SX420 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS 750D:
- More detail: Offers more megapixels (24 vs 19.9MP) with a 12% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.

Advantages of the Canon PowerShot SX420 IS:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Ready to shoot: Comes with an integrated lens, while the 750D requires a separate lens.
- More compact: Is smaller (104x69mm vs 132x101mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the 750D).
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Was introduced somewhat (10 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the 750D is the clear winner of the match-up (21 : 7 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.
How about other alternatives? Do the specifications of the Canon 750D 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 says little about, for example, the shooting experience and imaging performance of the 750D and the SX420 in practical situations. 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 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], digitalcameraworld [DCW], 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, please note that some of the review sites have changed their methodology and reporting over time.
