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 SX70 was launched at a markedly lower price (by 91 percent) than the ZX1, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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.

Of the two cameras under consideration, the Canon SX70 features a 1/2.3-inch sensor and the Zeiss ZX1 a full frame sensor. The sensor area in the ZX1 is 2986 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the SX70 has a native 4:3 aspect ratio, while the one in the ZX1 offers a 3:2 aspect.

With 37.4MP, the ZX1 offers a higher resolution than the SX70 (20.2MP), but the ZX1 nevertheless has larger individual pixels (pixel pitch of 4.81μm versus 1.18μm for the SX70) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the SX70 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Zeiss ZX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the ZX1 for good quality output (200 dots per inch) amounts to 37.4 x 25 inches or 95.1 x 63.4 cm, for very good quality (250 dpi) 30 x 20 inches or 76.1 x 50.7 cm, and for excellent quality (300 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm. The corresponding values for the Canon SX70 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The Canon PowerShot SX70 HS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Zeiss ZX1 are ISO 80 to ISO 51200 (no boost).

In terms of underlying technology, the SX70 is build around a BSI-CMOS sensor, while the ZX1 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the ZX1 offers a substantially higher resolution than the one in the SX70 (6221k vs 2360k dots).

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The SX70 has one, while the ZX1 does not. While the built-in flash of the SX70 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the ZX1 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The SX70 is equipped with a zoom lens, while the ZX1 comes with a built-in prime. The SX70 has a 21-1365mm f/3.4-6.5 optic and the ZX1 offers a 35mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Zeiss. The ZX1 offers the faster maximum aperture.

The SX70 writes its imaging data to SDXC cards, while the ZX1 uses an internal SSD.

Connectivity comparison

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 SX70 HS and Zeiss ZX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX70 has a microphone port, which is missing on the ZX1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The SX70 is a recent model that features in the current product line-up of Canon. In contrast, the ZX1 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the ZX1 from Zeiss. Further information on the features and operation of the SX70 and ZX1 can be found, respectively, in the Canon SX70 Manual (free pdf) or the online Zeiss ZX1 Manual.

Review summary

So what conclusions can be drawn? Is the Canon SX70 better than the Zeiss ZX1 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon PowerShot SX70 HS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.

• Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More prestigious: Has the Zeiss luxury appeal, which ensures a high resale value.

If the number of relative strengths (bullet points above) is taken as a guide, the ZX1 emerges as the winner of the match-up (16 : 13 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 SX70 and the Zeiss ZX1 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Prime Lens Compact 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 SX70 or the ZX1 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.

Expert reviews

This is why hands-on reviews by experts are important. 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 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 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.
