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. The SX70 was launched at a markedly lower price (by 31 percent) than the G1X, which puts it into a different market segment. 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.

Sensor comparison

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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G1 X features an 1.5-inch sensor and the Canon SX70 a 1/2.3-inch sensor. The sensor area in the SX70 is 89 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 5.6. 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 G1X (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the SX70 offers a higher resolution of 20.2 megapixels, compared with 14.2 MP of the G1X. 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 1.18μm versus 4.30μm for the G1X). However, it should be noted that the SX70 is much more recent (by 6 years and 8 months) than the G1X, 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 SX70 has no anti-alias filter installed, so that it can capture all the detail its 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 G1 X are 21.8 x 16.3 inches or 55.3 x 41.5 cm for good quality, 17.4 x 13.1 inches or 44.2 x 33.2 cm for very good quality, and 14.5 x 10.9 inches or 36.8 x 27.6 cm for excellent quality prints.

The Canon PowerShot G1 X has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Canon PowerShot SX70 HS are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the G1X is build around a CMOS sensor, while the SX70 uses a BSI-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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 G1X. It can shoot movie footage at 4K/30p, while the G1X is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the SX70 has an electronic viewfinder (2360k dots), while the G1X 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 following table reports on some other key feature differences and similarities of the Canon G1 X, the Canon SX70, and comparable cameras.

Both the G1X and the SX70 have zoom lenses built in. The G1X has a 28-112mm f/2.8-5.8 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 G1X. The G1X offers the faster maximum aperture.

Concerning the storage of imaging data, both the G1X 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 G1X cannot take advantage of Ultra High Speed SD cards.

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 G1 X 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 G1X has a hotshoe, while the SX70 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The SX70 is a recent model that features in the current product line-up of Canon. In contrast, the G1X has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the G1X was succeeded by the Canon G1X Mark II. Further information on the features and operation of the G1X and SX70 can be found, respectively, in the Canon G1 X Manual (free pdf) or the online Canon SX70 Manual.

Review summary

So how do things add up? Is the Canon G1 X better than the Canon SX70 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon PowerShot G1 X:

• 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.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/3.4).
• More compact: Is smaller (117x81mm vs 127x91mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 74g or 12 percent) and hence easier to carry around.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been available for much longer (launched in January 2012).

Arguments in favor of the Canon PowerShot SX70 HS:

• More detail: Has more megapixels (20.2 vs 14.2MP), which boosts linear resolution by 19%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 5).
• Better video: Provides higher definition movie capture (4K/30p vs 1080/24p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More framing info: Has an electronic viewfinder that displays shooting data.
• Faster burst: Shoots at higher frequency (10 vs 1.9 flaps/sec) to capture the decisive moment.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Gets more shots (325 versus 250) out of a single battery charge.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
• More modern: Reflects 6 years and 8 months of technical progress since the G1X launch.

If the count of relative strengths (bullet points above) is taken as a measure, the SX70 emerges as the winner of the match-up (15 : 12 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 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 G1 X and the Canon SX70 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom Camera listings 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 G1X or the SX70. 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
