Canon 20D vs G7X Mark II

The Canon EOS 20D and the Canon PowerShot G7 X Mark II are two digital cameras that were officially introduced, respectively, in August 2004 and February 2016. The 20D is a DSLR, while the G7X Mark II is a fixed lens compact. The cameras are based on an APS-C (20D) and an one-inch (G7X Mark II) sensor. The 20D has a resolution of 8.2 megapixels, whereas the G7X Mark II provides 20 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 20D and the Canon PowerShot G7 X Mark II? 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: Canon 20D vs G7X Mark II

The physical size and weight of the Canon 20D and the Canon G7 X Mark II 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 width, height and depth measures are rounded to the nearest millimeter.

Compare 20D versus G7X Mark II top
Comparison 20D or G7X Mark II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G7 X Mark II is considerably smaller (58 percent) than the Canon 20D. In this context, it is worth noting that neither the 20D nor the G7X Mark II are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark II has a lens built in, whereas the 20D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 20D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 20D gets 700 shots out of its BP-511A battery, while the G7X Mark II can take 265 images on a single charge of its NB-13L power pack. The power pack in the G7X Mark II can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 G7X Mark II was launched at a lower price than the 20D, despite having a lens built 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 20D vs G7X Mark II

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 20D features an APS-C sensor and the Canon G7 X Mark II an one-inch sensor. The sensor area in the G7X Mark II is 66 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the G7X Mark II uses a more advanced image processing engine (DIGIC 7) than the 20D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.

Canon 20D and Canon G7 X Mark II sensor measures

Despite having a smaller sensor, the G7X Mark II offers a higher resolution of 20 megapixels, compared with 8.2 MP of the 20D. 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 2.41μm versus 6.42μm for the 20D). However, it should be noted that the G7X Mark II is much more recent (by 11 years and 6 months) than the 20D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon G7 X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X Mark II for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inch or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inch or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inch or 46.3 x 30.9 cm. The corresponding values for the Canon 20D are 17.5 x 11.7 inch or 44.5 x 29.7 cm for good quality, 14 x 9.3 inch or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inch or 29.7 x 19.8 cm for excellent quality prints.

The Canon EOS 20D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon PowerShot G7 X Mark II are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 125-25600.

One feature that is present on the 20D, but is missing on the G7X Mark II 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 G7X Mark II has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 20D does not have a selfie-screen.

The Canon G7 X Mark II has 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 20D writes its imaging data to Compact Flash cards, while the G7X Mark II uses SDXC cards.

 

Connectivity comparison: Canon 20D vs G7X Mark II

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.

It is notable that the 20D has a hotshoe, while the G7X Mark II does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Canon 20D (unlike the G7X Mark II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The G7X Mark II is a recent model that features in the current product line-up of Canon. In contrast, the 20D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 20D was succeeded by the Canon 30D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.


Review summary: Canon 20D vs G7X Mark II

So what is the bottom line? Is the Canon 20D better than the Canon G7 X Mark II or vice versa? The listing below highlights the relative strengths of the two models.

  • Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 2).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 118k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Ready to shoot: Comes with an integrated lens, while the 20D requires a separate lens.
  • More compact: Is smaller (106x61mm vs 144x106mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the 20D).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 11 years and 6 months of technical progress since the 20D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G7X Mark II is the clear winner of the contest (19 : 8 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 20D and the Canon G7 X Mark II place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 20D and the G7X Mark II 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.

Expert reviews: Canon 20D vs G7X Mark II

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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. 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.
