Canon 250D vs Panasonic GH1

The Canon EOS 250D (called Canon SL3 in some regions) and the Panasonic Lumix DMC-GH1 are two digital cameras that were officially introduced, respectively, in April 2019 and March 2009. The 250D is a DSLR, while the GH1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (250D) and a Four Thirds (GH1) sensor. The Canon has a resolution of 24 megapixels, whereas the Panasonic provides 12 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 250D and the Panasonic Lumix DMC-GH1? 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 physical size and weight of the Canon 250D and the Panasonic GH1 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.

The 250D can be obtained in two different colors (black, white), while the GH1 is also available in two color-versions, but different ones (black, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH1 is somewhat smaller (2 percent) than the Canon 250D. Moreover, the GH1 is markedly lighter (14 percent) than the 250D. In this context, it is worth noting that neither the 250D nor the GH1 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 (250D) and the Micro Four Thirds Lens Catalog (GH1). Mirrorless cameras, such as the GH1, 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 250D gets 1070 shots out of its Canon LP-E17 battery, while the GH1 can take 300 images on a single charge of its Panasonic DMW-BLB13 power pack.

The price is, of course, an important factor in any camera decision. 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 250D was launched at a markedly lower price (by 33 percent) than the GH1, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 250D features an APS-C sensor and the Panasonic GH1 a Four Thirds sensor. The sensor area in the GH1 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 250D has a native 3:2 aspect ratio, while the one in the GH1 offers a 4:3 aspect.

With 24MP, the 250D offers a higher resolution than the GH1 (12MP), but the 250D has smaller individual pixels (pixel pitch of 3.72μm versus 4.33μm for the GH1). However, the 250D is a much more recent model (by 10 years and 1 month) than the GH1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 250D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 250D 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 GH1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The 250D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 250D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Panasonic Lumix DMC-GH1 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 250D provides a higher video resolution than the GH1. It can shoot video footage at 4K/25p, while the Panasonic is limited to 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GH1 has an electronic viewfinder (1440k dots), while the 250D 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 GH1 offers a wider field of view (100%) than the one in the 250D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the GH1 has a higher magnification (0.70x vs 0.54x), 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 250D and Panasonic GH1 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 250D has a touchscreen, while the GH1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon 250D 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 250D writes its imaging data to SDXC cards, while the GH1 uses SDHC cards. The 250D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GH1 cannot take advantage of Ultra High Speed SD cards.

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 250D and Panasonic Lumix DMC-GH1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 250D offers wifi support, while the GH1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The 250D is a recent model that features in the current product line-up of Canon. In contrast, the GH1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the GH1 was succeeded by the Panasonic GH2. Further information on the features and operation of the 250D and GH1 can be found, respectively, in the Canon 250D Manual (free pdf) or the online Panasonic GH1 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon 250D and the Panasonic GH1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS 250D:

• More detail: Offers more megapixels (24 vs 12MP) with a 44% higher linear resolution.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better video: Provides higher definition movie capture (4K/25p vs 1080/24p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Longer lasting: Can take more shots (1070 versus 300) on a single battery charge.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
• More modern: Reflects 10 years and 1 month of technical progress since the GH1 launch.

Reasons to prefer the Panasonic Lumix DMC-GH1:

• 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 0.54x).
• Less heavy: Has a lower weight (by 64g or 14 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More heavily discounted: Has been around for much longer (launched in March 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the 250D is the clear winner of the match-up (18 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 250D and the Panasonic GH1 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 250D or the GH1. 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.

The review scores listed above should be treated 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 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.
