Canon 750D vs G3X
The Canon EOS 750D (called Canon T6i in some regions) and the Canon PowerShot G3 X are two digital cameras that were revealed to the public, respectively, in February 2015 and June 2015. The 750D is a DSLR, while the G3X is a fixed lens compact. The cameras are based on an APS-C (750D) and an one-inch (G3X) sensor. The 750D has a resolution of 24 megapixels, whereas the G3X 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 750D and the Canon PowerShot G3 X? 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.
An illustration of the physical size and weight of the Canon 750D and the Canon G3 X is provided 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G3 X is notably smaller (29 percent) than the Canon 750D. It is noteworthy in this context that the G3X is splash and dust-proof, while the 750D does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G3X has a lens built in, whereas the 750D 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 750D and their specifications in the Canon EF Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.
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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 750D features an APS-C sensor and the Canon G3 X an one-inch sensor. The sensor area in the G3X is 65 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.
With 24MP, the 750D offers a higher resolution than the G3X (20MP), but the 750D nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G3X) due to its larger sensor. However, the G3X is a somewhat more recent model (by 4 months) than the 750D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 750D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 750D for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon G3 X are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.
The 750D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 750D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon PowerShot G3 X are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 125-25600.
In terms of underlying technology, the 750D is build around a CMOS sensor, while the G3X 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. Of the two cameras under review, the 750D has a notably higher overall DXO score than the G3X (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.3 bits higher color depth, 0.3 EV of lower dynamic range, and 0.8 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G3X provides a faster frame rate than the 750D. It can shoot movie footage at 1080/60p, while the 750D is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 750D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G3X relies on live view and the rear LCD for framing. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The adjacent table lists some of the other core features of the Canon 750D and Canon G3 X along with similar information for a selection of comparators.

Concerning the storage of imaging data, both the 750D and the G3X 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.
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 EOS 750D and Canon PowerShot G3 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The G3X is a recent model that features in the current product line-up of Canon. In contrast, the 750D has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 750D was succeeded by the Canon 800D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So how do things add up? Which of the two cameras – the Canon 750D or the Canon G3 X – 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 EOS 750D:
- More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.3 bits more color depth).
- Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (440 versus 300) on a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in February 2015).
Arguments in favor of the Canon PowerShot G3 X:
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
- Faster burst: Shoots at higher frequency (5.9 vs 5 flaps/sec) to capture the decisive moment.
- Ready to shoot: Comes with an integrated lens, while the 750D requires a separate lens.
- More compact: Is smaller (123x77mm vs 132x101mm) and will fit more readily into a bag.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More modern: Was introduced somewhat (4 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the 750D comes out slightly ahead of the G3X (11 : 10 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 750D and the Canon G3 X place the cameras among the top in their class? Find out in the latest Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the 750D and the G3X in practical situations. 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 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
