Canon 1100D vs OM System OM-1

The Canon EOS 1100D (called Canon T3 in some regions) and the OM System OM-1 are two digital cameras that were officially introduced, respectively, in February 2011 and February 2022. The 1100D is a DSLR, while the OM-1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (1100D) and a Four Thirds (OM-1) sensor. The Canon has a resolution of 12.2 megapixels, whereas the OM System provides 20.2 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the Canon 1100D and the OM System OM-1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

Compare 1100D versus OM-1 top
Comparison 1100D or OM-1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the OM System OM-1 is somewhat smaller (4 percent) than the Canon 1100D. However, the OM-1 is markedly heavier (21 percent) than the 1100D. It is noteworthy in this context that the OM-1 is splash and dust-proof, while the 1100D 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 (1100D) and the Micro Four Thirds Lens Catalog (OM-1). Mirrorless cameras, such as the OM-1, 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 1100D gets 700 shots out of its Canon LP-E10 battery, while the OM-1 can take 520 images on a single charge of its OM System BLX-1 power pack. The power pack in the OM-1 can be charged via the USB port, which can be very convenient when travelling.

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

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 1100D was launched at a markedly lower price (by 80 percent) than the OM-1, 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.

Sensor comparison

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 1100D features an APS-C sensor and the OM System OM-1 a Four Thirds sensor. The sensor area in the OM-1 is 30 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 1100D has a native 3:2 aspect ratio, while the one in the OM-1 offers a 4:3 aspect.

Canon 1100D and OM System OM-1 sensor measures

Despite having a smaller sensor, the OM-1 offers a higher resolution of 20.2 megapixels, compared with 12.2 MP of the 1100D. 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 3.34μm versus 5.15μm for the 1100D). However, it should be noted that the OM-1 is much more recent (by 11 years) than the 1100D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the OM-1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the OM System OM-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the OM-1 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Canon 1100D are 21.4 x 14.2 inches or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inches or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.1 cm for excellent quality prints.

The OM-1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the 1100D, the OM-1 has the capacity to capture high quality composite images (80MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Canon EOS 1100D has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the OM System OM-1 are ISO 80 to ISO 25600, with the possibility to increase the ISO range to 80-102400.

In terms of underlying technology, the 1100D is build around a CMOS sensor, while the OM-1 uses a Stacked BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

1100D versus OM-1 MP

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").

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the OM-1 provides a better video resolution than the 1100D. It can shoot movie footage at 4K/60p, while the Canon is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the OM-1 has an electronic viewfinder (5760k dots), while the 1100D 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 OM-1 offers a wider field of view (100%) than the one in the 1100D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the OM-1 has a higher magnification (0.82x vs 0.50x), 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 1100D and OM System OM-1 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 difference between the cameras concerns the presence of an on-board flash. The 1100D has one, while the OM-1 does not. While the built-in flash of the 1100D is not very powerful, it can at times be useful as a fill-in light.

The OM-1 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 1100D 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 OM-1 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 OM System OM-1 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 1100D and the OM-1 write their files to SDXC cards. The OM-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 1100D only has one slot. The OM-1 supports UHS-II cards (on both slots), while the 1100D cannot take advantage of Ultra High Speed SD cards.

It is notable that the OM-1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1100D does not provide wifi capability.

Studio photographers will appreciate that the OM System OM-1 (unlike the 1100D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1100D and the OM-1 have been discontinued, but can regularly be found used on ebay. The 1100D was replaced by the Canon 1200D, while the OM-1 was followed by the OM System OM-1 II. Further information on the features and operation of the 1100D and OM-1 can be found, respectively, in the Canon 1100D Manual (free pdf) or the online OM System OM-1 Manual.

If the count of individual advantages (bullet points above) is taken as a guide, the OM-1 is the clear winner of the contest (30 : 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 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.

1100D 07:30 OM-1

How about other alternatives? Do the specifications of the Canon 1100D and the OM System OM-1 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 1100D or the OM-1 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 expert reviews 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
