Canon 1D versus Canon G1 X Mark III

The Canon EOS-1D and the Canon PowerShot G1 X Mark III are two digital cameras that were announced, respectively, in September 2001 and October 2017. The 1D is a DSLR, while the G1X Mark III is a fixed lens compact. The cameras are based on an APS-H (1D) and an APS-C (G1X Mark III) sensor. The 1D has a resolution of 4.1 megapixel, whereas the G1X Mark III provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1D vs Canon G1 X Mark III

The physical size and weight of the Canon 1D and the Canon G1 X Mark III are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the 1D – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G1 X Mark III is considerably smaller (64 percent) than the Canon 1D. 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.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark III has a lens build in, whereas the 1D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the 1D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 1D gets 500 shots out of its NP-E3 battery, while the G1X Mark III can take 200 images on a single charge of its NB-13L power pack. As can be seen in the images above, the 1D has a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power.

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 G1X Mark III was launched at a lower price than the 1D, despite having a lens build in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison: Canon 1D vs Canon G1 X Mark III

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1D features an APS-H sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the G1X Mark III uses a more advanced image processing engine (DIGIC 7) than the 1D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the G1X Mark III offers a higher resolution of 24 megapixel, compared with 4.1 MP of the 1D. 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 11.56μm for the 1D). However, it should be noted that the G1X Mark III is much more recent (by 16 years) than the 1D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The G1X Mark III has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The G1X Mark III indeed provides for movie recording, while the 1D does not. The highest resolution format that the G1X Mark III can use is 1080/60p.

Feature comparison: Canon 1D vs Canon G1 X Mark III

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), while the 1D 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 table below summarizes some of the other core capabilities of the Canon 1D and Canon G1 X Mark III in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

One feature that is present on the 1D, but is missing on the G1X Mark III is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The 1D writes its imaging data to Compact Flash cards, while the G1X Mark III uses SDXC cards. The 1D features dual card slots, which can be very useful in case a memory card fails. In contrast, the G1X Mark III only has one slot.

The G1X Mark III is a recent model that features in the current product line-up of Canon. In contrast, the 1D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1D was succeeded by the Canon 1D Mark II.

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 (20 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 1D or the G1X Mark III. 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. 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 are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
