Canon SX400 vs SX70
The Canon PowerShot SX400 IS and the Canon PowerShot SX70 HS are two digital cameras that were revealed to the public, respectively, in July 2014 and September 2018. Both the SX400 and the SX70 are fixed lens compact cameras that are equipped with a 1/2.3-inch sensor. The SX400 has a resolution of 15.9 megapixels, whereas the SX70 provides 20.2 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 PowerShot SX400 IS and the Canon PowerShot SX70 HS? 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 SX400 and the Canon SX70 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 width, height and depth measures are rounded to the nearest millimeter.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX400 was launched at a markedly lower price (by 55 percent) than the SX70, 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.
The size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
Technology-wise, the SX70 uses a more advanced image processing engine (DIGIC 8) than the SX400 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.
While the two cameras under review share the same sensor size, the SX70 offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the SX400. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the SX70 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.33μm for the SX400). However, it should be noted that the SX70 is much more recent (by 4 years and 1 month) than the SX400, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The resolution advantage of the Canon SX70 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX70 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Canon SX400 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The Canon PowerShot SX400 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot SX70 HS are ISO 100 to ISO 3200 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the SX70 provides a better video resolution than the SX400. It can shoot movie footage at 4K/30p, while the SX400 is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the SX70 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX400 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon SX400 and Canon SX70 in connection with corresponding information for a sample of similar cameras.
|4.||Canon G9 X Mark II||none||n||3.0||1040||fixed||Y||1/2000s||8.2||Y||Y|
Both the SX400 and the SX70 have zoom lenses built in. The SX400 has a 24-720mm f/3.4-5.8 optic and the SX70 offers a 21-1365mm f/3.4-6.5 (focal lengths in full frame equivalent terms). Hence, the SX70 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the SX400. Both cameras offer the same maximum aperture.
Concerning the storage of imaging data, both the SX400 and the SX70 write their files to SDXC cards. The SX70 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX400 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 PowerShot SX400 IS and Canon PowerShot SX70 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX70 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the SX400 does not provide wifi capability.
The SX70 is a recent model that features in the current product line-up of Canon. In contrast, the SX400 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the SX400 was succeeded by the Canon SX410. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

If the count of individual advantages (bullet points above) is taken as a guide, the SX70 is the clear winner of the contest (17 : 4 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 SX400 and the Canon SX70 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX400 or the SX70. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why expert reviews are important. 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
