The price is, of course, an important factor in any camera decision. 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 two cameras under review were launched at the same price and fall into the same 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: Fujifilm X100S vs Canon G1 X Mark III

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 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 G1X Mark III is 10 percent smaller. 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Fujifilm X100S and Canon G1 X Mark III sensor measures

Despite having a smaller sensor, the G1X Mark III offers a higher resolution of 24 megapixel, compared with 16 MP of the X100S. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 4.80μm for the X100S). However, it should be noted that the G1X Mark III is much more recent (by 4 years and 9 months) than the X100S, 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 X100S has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G1X Mark III has a touchscreen, while the X100S has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The G1X Mark III is equipped with a zoom lens, while the X100S comes with a build-in prime. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the X100S 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 X100S offers the faster maximum aperture.

Both the X100S and the G1X Mark III write their imaging data to SDXC cards.

If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark III is the clear winner of the contest (14 : 5 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.

X100S 05:14 G1X Mark III

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the X100S and the G1X Mark III in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, 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 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.
