Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G1 X Mark III and the Fujifilm X100V? 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.

Body comparison

The physical size and weight of the Canon G1 X Mark III and the Fujifilm X100V are illustrated 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 size dimensions are rounded to the nearest millimeter.

The X100V can be obtained in two different colors (black, silver), while the G1X Mark III 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 Fujifilm X100V is notably larger (7 percent) than the Canon G1 X Mark III. Moreover, the X100V is markedly heavier (20 percent) than the G1X Mark III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

Concerning battery life, the G1X Mark III gets 200 shots out of its Canon NB-13L battery, while the X100V can take 420 images on a single charge of its Fujifilm NP-W126S power pack. The power pack in the X100V can be charged via the USB port, which can be very convenient when travelling.

Convert to Imperial

Any camera decision will naturally be influenced heavily by the price. 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 G1X Mark III was somewhat cheaper (by 7 percent) than the X100V at launch, but both cameras fall into the same price category. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the X100V is 11 percent bigger. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 26MP, the X100V offers a higher resolution than the G1X Mark III (24MP), but the X100V nevertheless has marginally larger individual pixels (pixel pitch of 3.76μm versus 3.72μm for the G1X Mark III) due to its larger sensor. Moreover, the X100V is a much more recent model (by 2 years and 3 months) than the G1X Mark III, 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 X100V has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Canon PowerShot G1 X Mark III has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Fujifilm X100V are ISO 160 to ISO 12800, with the possibility to increase the ISO range to 80-51200.

In terms of underlying technology, the G1X Mark III is build around a CMOS sensor, while the X100V uses a BSI-CMOS imager. Like most digital cameras, the G1X Mark III uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X100V employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 have a sensor with sufficiently fast read-out times for moving pictures, but the X100V provides a better video resolution than the G1X Mark III. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.

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 X100V offers a substantially higher resolution than the one in the G1X Mark III (3690k vs 2360k dots). The table below summarizes some of the other core capabilities of the Canon G1 X Mark III and Fujifilm X100V in connection with corresponding information for a sample of similar cameras.

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 G1X Mark III has one, while the X100V does not. While the built-in flash of the G1X Mark III 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 X100V 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 Canon G1 X Mark III and the Fujifilm X100V both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The G1X Mark III is equipped with a zoom lens, while the X100V comes with a built-in prime. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the X100V offers a 35mm f/2.0 (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 Fujifilm. The X100V offers the faster maximum aperture.

Concerning the storage of imaging data, both the G1X Mark III and the X100V write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 Mark III and Fujifilm X100V and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X100V has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G1X Mark III does not feature such a mic input.

Both the G1X Mark III and the X100V have been discontinued, but can regularly be found used on ebay. The X100V was replaced by the Fujifilm X100VI, while the G1X Mark III does not have a direct successor. Further information on the features and operation of the G1X Mark III and X100V can be found, respectively, in the Canon G1 X Mark III Manual (free pdf) or the online Fujifilm X100V Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon G1 X Mark III or the Fujifilm X100V – 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.

Advantages of the Canon PowerShot G1 X Mark III:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Less heavy: Is lighter (by 79g or 17 percent) and hence easier to carry around.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More heavily discounted: Has been available for much longer (launched in October 2017).

Reasons to prefer the Fujifilm X100V:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (3690k vs 2360k dots).
• More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (11 vs 9 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.8).
• Longer lasting: Gets more shots (420 versus 200) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
• More modern: Reflects 2 years and 3 months of technical progress since the G1X Mark III launch.

If the count of individual advantages (bullet points above) is taken as a guide, the X100V is the clear winner of the contest (13 : 9 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Mark III and the Fujifilm X100V place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G1X Mark III or the X100V. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews 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 above review scores should be interpreted 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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
