Canon T6i vs Panasonic G7

The Canon EOS Rebel T6i (called Canon 750D in some regions) and the Panasonic Lumix DMC-G7 are two digital cameras that were revealed to the public, respectively, in February 2015 and May 2015. The T6i is a DSLR, while the G7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (T6i) and a Four Thirds (G7) sensor. The Canon has a resolution of 24 megapixels, whereas the Panasonic provides 15.8 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 Rebel T6i and the Panasonic Lumix DMC-G7? 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 side-by-side display below illustrates the physical size and weight of the Canon T6i and the Panasonic G7. 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 dimensions are rounded to the nearest millimeter.

The G7 can be obtained in two different colors (black, silver), while the T6i 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 Panasonic G7 is notably smaller (19 percent) than the Canon T6i. Moreover, the G7 is markedly lighter (26 percent) than the T6i. In this context, it is worth noting that neither the T6i nor the G7 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (T6i) and the Micro Four Thirds Lens Catalog (G7). Mirrorless cameras, such as the G7, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the T6i gets 440 shots out of its Canon LP-E17 battery, while the G7 can take 350 images on a single charge of its Panasonic DMW-BLC12 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. 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 G7 was launched at a somewhat lower price (by 13 percent) than the T6i, which makes it more attractive for photographers on a tight budget. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 T6i features an APS-C sensor and the Panasonic G7 a Four Thirds sensor. The sensor area in the G7 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the T6i has a native 3:2 aspect ratio, while the one in the G7 offers a 4:3 aspect.

With 24MP, the T6i offers a higher resolution than the G7 (15.8MP), but the T6i has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.77μm for the G7). Moreover, the G7 is a somewhat more recent model (by 3 months) than the T6i, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon T6i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T6i 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 Panasonic G7 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.

The T6i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS Rebel T6i 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 Panasonic Lumix DMC-G7 are ISO 160 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G7 provides a better video resolution than the T6i. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G7 has an electronic viewfinder (2360k dots), while the T6i 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 viewfinder in the G7 offers a wider field of view (100%) than the one in the T6i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the G7 has a higher magnification (0.70x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon T6i and Panasonic G7 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

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 G7 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 Panasonic G7 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.

Concerning the storage of imaging data, both the T6i and the G7 write their files to SDXC cards. The G7 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the T6i can use UHS-I cards (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 EOS Rebel T6i and Panasonic Lumix DMC-G7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the T6i and the G7 have been discontinued, but can regularly be found used on ebay. The T6i was replaced by the Canon T7i, while the G7 was followed by the Panasonic G85. Further information on the features and operation of the T6i and G7 can be found, respectively, in the Canon T6i Manual (free pdf) or the online Panasonic G7 Manual.

Review summary

So what conclusions can be drawn? Is the Canon T6i better than the Panasonic G7 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS Rebel T6i:

• More detail: Offers more megapixels (24 vs 15.8MP) with a 26% higher linear resolution.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Longer lasting: Can take more shots (440 versus 350) on a single battery charge.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More heavily discounted: Has been on the market for longer (launched in February 2015).

Advantages of the Panasonic Lumix DMC-G7:

• Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.51x).
• Faster burst: Shoots at higher frequency (7 vs 5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (125x86mm vs 132x101mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 145g or 26 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
• More modern: Was introduced somewhat (3 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the G7 is the clear winner of the contest (13 : 6 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 T6i and the Panasonic G7 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T6i or the G7. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
