Canon T2i vs Panasonic GH5s
The Canon EOS Rebel T2i (called Canon 550D in some regions) and the Panasonic Lumix DC-GH5s are two digital cameras that were revealed to the public, respectively, in February 2010 and January 2018. The T2i is a DSLR, while the GH5s is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (T2i) and a Four Thirds (GH5s) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Panasonic provides 9.9 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 T2i and the Panasonic Lumix DC-GH5s? 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.
The physical size and weight of the Canon T2i and the Panasonic GH5s are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 Panasonic GH5s is notably larger (8 percent) than the Canon T2i. Moreover, the GH5s is markedly heavier (25 percent) than the T2i. It is noteworthy in this context that the GH5s is splash and dust-proof, while the T2i does not feature any corresponding weather-sealing.
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 (T2i) and the Micro Four Thirds Lens Catalog (GH5s). Mirrorless cameras, such as the GH5s, 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.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T2i was launched at a markedly lower price (by 72 percent) than the GH5s, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon T2i features an APS-C sensor and the Panasonic GH5s a Four Thirds sensor. The sensor area in the GH5s 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 T2i has a native 3:2 aspect ratio, while the one in the GH5s offers a 4:3 aspect.
With 17.9MP, the T2i offers a higher resolution than the GH5s (9.9MP), but the T2i has smaller individual pixels (pixel pitch of 4.31μm versus 4.77μm for the GH5s). Moreover, the GH5s is a much more recent model (by 7 years and 11 months) than the T2i, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the GH5s has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon T2i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T2i 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 GH5s are 18.4 x 13.5 inches or 46.7 x 34.3 cm for good quality, 14.7 x 10.8 inches or 37.4 x 27.4 cm for very good quality, and 12.3 x 9 inches or 31.2 x 22.9 cm for excellent quality prints.
The Canon EOS Rebel T2i 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 DC-GH5s are ISO 160 to ISO 51200, with the possibility to increase the ISO range to 80-204800.
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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GH5s provides a better video resolution than the T2i. It can shoot movie footage at 4K/60p, while the Canon is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GH5s has an electronic viewfinder (3680k dots), while the T2i 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 GH5s offers a wider field of view (100%) than the one in the T2i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the GH5s has a higher magnification (0.76x vs 0.54x), 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 T2i and Panasonic GH5s along with similar information for a selection of comparators.
One difference between the cameras concerns the presence of an on-board flash. The T2i has one, while the GH5s does not. While the built-in flash of the T2i is not very powerful, it can at times be useful as a fill-in light.The GH5s 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 T2i 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 GH5s 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 GH5s 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 T2i and the GH5s write their files to SDXC cards. The GH5s features dual card slots, which can be very useful in case a memory card fails. In contrast, the T2i only has one slot. The GH5s supports UHS-II cards (on both slots), while the T2i cannot take advantage of Ultra High Speed SD cards.
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 T2i and Panasonic Lumix DC-GH5s and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

| NFC |
It is notable that the GH5s offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the T2i does not provide wifi capability.
Studio photographers will appreciate that the Panasonic GH5s (unlike the T2i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The GH5s is a recent model that features in the current product line-up of Panasonic. In contrast, the T2i has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the T2i was succeeded by the Canon T3i. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.
So how do things add up? Is there a clear favorite between the Canon T2i and the Panasonic GH5s? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

If the count of individual advantages (bullet points above) is taken as a guide, the GH5s is the clear winner of the contest (25 : 7 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 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.
How about other alternatives? Do the specifications of the Canon T2i and the Panasonic GH5s 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 T2i or the GH5s perform in practice. 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 ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
