Canon T3i vs Panasonic GX7

The Canon EOS Rebel T3i (called Canon 600D in some regions) and the Panasonic Lumix DMC-GX7 are two digital cameras that were officially introduced, respectively, in February 2011 and August 2013. The T3i is a DSLR, while the GX7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (T3i) and a Four Thirds (GX7) sensor. The Canon has a resolution of 17.9 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon T3i and the Panasonic GX7. 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.

The GX7 can be obtained in two different colors (black, silver), while the T3i is only available in black.

Size Canon T3i vs Panasonic GX7
Compare T3i versus GX7 top
Comparison T3i or GX7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX7 is considerably smaller (34 percent) than the Canon T3i. Moreover, the GX7 is markedly lighter (29 percent) than the T3i. In this context, it is worth noting that neither the T3i nor the GX7 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 (T3i) and the Micro Four Thirds Lens Catalog (GX7). Mirrorless cameras, such as the GX7, 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 T3i gets 440 shots out of its Canon LP-E8 battery, while the GX7 can take 350 images on a single charge of its Panasonic DMW-BLG10 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or 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 T3i was launched at a markedly lower price (by 40 percent) than the GX7, which puts it into a different market segment. 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon T3i features an APS-C sensor and the Panasonic GX7 a Four Thirds sensor. The sensor area in the GX7 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 T3i has a native 3:2 aspect ratio, while the one in the GX7 offers a 4:3 aspect.

Canon T3i and Panasonic GX7 sensor measures

With 17.9MP, the T3i offers a higher resolution than the GX7 (15.8MP), but the T3i nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.77μm for the GX7) due to its larger sensor. However, the GX7 is a much more recent model (by 2 years and 5 months) than the T3i, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon T3i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T3i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Panasonic GX7 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 Canon EOS Rebel T3i has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Panasonic Lumix DMC-GX7 are ISO 125 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.

T3i versus GX7 MP

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 consideration, the GX7 has a markedly higher DXO score than the T3i (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.5 bits higher color depth, 0.7 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. 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 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 GX7 provides a faster frame rate than the T3i. It can shoot movie footage at 1080/60p, 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 GX7 has an electronic viewfinder (2760k dots), while the T3i 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 GX7 offers a wider field of view (100%) than the one in the T3i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the GX7 has a higher magnification (0.70x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon T3i and Panasonic GX7 in connection with corresponding information for a sample of similar cameras.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX7 has a touchscreen, while the T3i has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The T3i has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the GX7 does not have a selfie-screen.

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 GX7 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 GX7 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 T3i and the GX7 write their files to SDXC cards. The GX7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the T3i cannot take advantage of Ultra High Speed SD cards.

It is notable that the T3i has a microphone port, which is missing on the GX7. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the T3i and the GX7 have been discontinued, but can regularly be found used on ebay. The T3i was replaced by the Canon T4i, while the GX7 was followed by the Panasonic GX85. Further information on the features and operation of the T3i and GX7 can be found, respectively, in the Canon T3i Manual (free pdf) or the online Panasonic GX7 Manual.

If the number of relative strengths (bullet points above) is taken as a guide, the GX7 is the clear winner of the contest (19 : 8 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

T3i 08:19 GX7

How about other alternatives? Do the specifications of the Canon T3i and the Panasonic GX7 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the T3i or the GX7 perform in practice. 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

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 (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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
