Canon 10D vs Panasonic GM1
The Canon EOS 10D and the Panasonic Lumix DMC-GM1 are two digital cameras that were announced, respectively, in February 2003 and October 2013. The 10D is a DSLR, while the GM1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (10D) and a Four Thirds (GM1) sensor. The Canon has a resolution of 6.3 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 10D and the Panasonic Lumix DMC-GM1? 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 10D and the Panasonic GM1 are illustrated 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.
The GM1 can be obtained in three different colors (black, silver, red), while the 10D 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 GM1 is considerably smaller (66 percent) than the Canon 10D. Moreover, the GM1 is substantially lighter (76 percent) than the 10D. In this context, it is worth noting that neither the 10D nor the GM1 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 (10D) and the Micro Four Thirds Lens Catalog (GM1). Mirrorless cameras, such as the GM1, 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GM1 was launched at a markedly lower price (by 63 percent) than the 10D, 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.
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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 10D features an APS-C sensor and the Panasonic GM1 a Four Thirds sensor. The sensor area in the GM1 is 34 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 10D has a native 3:2 aspect ratio, while the one in the GM1 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
Despite having a smaller sensor, the GM1 offers a higher resolution of 15.8 megapixels, compared with 6.3 MP of the 10D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 7.38μm for the 10D). However, it should be noted that the GM1 is much more recent (by 10 years and 7 months) than the 10D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Panasonic GM1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GM1 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Canon 10D are 15.4 x 10.2 inches or 39 x 26 cm for good quality, 12.3 x 8.2 inches or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inches or 26 x 17.3 cm for excellent quality prints.
The Canon EOS 10D has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Panasonic Lumix DMC-GM1 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 125-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 GM1 has a markedly higher DXO score than the 10D (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1.2 bits higher color depth, 0.8 EV in additional dynamic range, and 0.2 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.
|Panasonic GM1||Four Thirds||15.8||4592||3448||1080/60i||22.3||11.7||660||66|
|Panasonic GM5||Four Thirds||15.8||4592||3448||1080/60p||22.1||11.7||721||66|

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GM1 indeed provides for movie recording, while the 10D does not. The highest resolution format that the GM1 can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 10D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GM1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 10D and Panasonic GM1 in connection with corresponding information for a sample of similar cameras.
One feature that is present on the 10D, but is missing on the GM1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
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 GM1 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 GM1 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 10D writes its imaging data to Compact Flash cards, while the GM1 uses SDXC 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 10D and Panasonic Lumix DMC-GM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 10D has a hotshoe, while the GM1 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Studio photographers will appreciate that the Canon 10D (unlike the GM1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 10D and the GM1 have been discontinued, but can regularly be found used on eBay. The 10D was replaced by the Canon 20D, while the GM1 was followed by the Panasonic GM5. 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 what is the bottom line? Which of the two cameras – the Canon 10D or the Panasonic GM1 – 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 10D:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- Longer lasting: Can take more shots (500 versus 230) on a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been available for much longer (launched in February 2003).
Reasons to prefer the Panasonic Lumix DMC-GM1:
- More detail: Has more megapixels (15.8 vs 6.3MP), which boosts linear resolution by 56%.
- Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.2 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
- Broader imaging potential: Can capture not only stills but also 1080/60i video.
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1036k vs 118k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (5 vs 3 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 (99x55mm vs 150x107mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 646g or 76 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More affordable: Was introduced into a lower priced category (63 percent cheaper at launch).
- More modern: Reflects 10 years and 7 months of technical progress since the 10D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the GM1 is the clear winner of the contest (18 : 7 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 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 10D or the GM1. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
