Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS Rebel T1i and the Olympus PEN E-PL9? 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 T1i and the Olympus E-PL9 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 width, height and depth dimensions are rounded to the nearest millimeter.

The E-PL9 can be obtained in four different colors (black, brown, blue, white), while the T1i 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 Olympus E-PL9 is considerably smaller (37 percent) than the Canon T1i. Moreover, the E-PL9 is markedly lighter (27 percent) than the T1i. In this context, it is worth noting that neither the T1i nor the E-PL9 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 (T1i) and the Micro Four Thirds Lens Catalog (E-PL9). Mirrorless cameras, such as the E-PL9, 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 T1i gets 400 shots out of its Canon LP-E5 battery, while the E-PL9 can take 350 images on a single charge of its Olympus BLS-50 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 E-PL9 was launched at a somewhat lower price (by 25 percent) than the T1i, which makes it more attractive for photographers on a tight budget. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon T1i features an APS-C sensor and the Olympus E-PL9 a Four Thirds sensor. The sensor area in the E-PL9 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 T1i has a native 3:2 aspect ratio, while the one in the E-PL9 offers a 4:3 aspect.

Despite having a smaller sensor, the E-PL9 offers a slightly higher resolution of 15.9 megapixels, compared with 15.1 MP of the T1i. 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 3.76μm versus 4.69μm for the T1i). However, it should be noted that the E-PL9 is much more recent (by 8 years and 10 months) than the T1i, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The Canon EOS Rebel T1i 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 Olympus PEN E-PL9 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

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 determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 E-PL9 provides a better video resolution than the T1i. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/20p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the T1i has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL9 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon T1i and Olympus E-PL9 along with similar information for a selection of comparators.

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 E-PL9 has a touchscreen, while the T1i has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 E-PL9 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 Olympus E-PL9 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 T1i writes its imaging data to SDHC cards, while the E-PL9 uses SDXC cards. The E-PL9 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the T1i 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 Rebel T1i and Olympus PEN E-PL9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PL9 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the T1i does not provide wifi capability.

Both the T1i and the E-PL9 have been discontinued, but can regularly be found used on ebay. The T1i was replaced by the Canon T2i, while the E-PL9 was followed by the Olympus E-PL10. Further information on the features and operation of the T1i and E-PL9 can be found, respectively, in the Canon T1i Manual (free pdf) or the online Olympus E-PL9 Manual.

Review summary

So what conclusions can be drawn? Is the Canon T1i better than the Olympus E-PL9 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS Rebel T1i:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• Longer lasting: Can take more shots (400 versus 350) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in March 2009).

Arguments in favor of the Olympus PEN E-PL9:

• Better video: Provides higher definition movie capture (4K/30p vs 1080/20p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (8.6 vs 3.4 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 (117x68mm vs 129x98mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 140g or 27 percent) and is thus easier to take along.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• 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 released into a lower priced segment (25 percent cheaper at launch).
• More modern: Reflects 8 years and 10 months of technical progress since the T1i launch.

If the number of relative strengths (bullet points above) is taken as a guide, the E-PL9 is the clear winner of the contest (17 : 3 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 T1i and the Olympus E-PL9 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 T1i or the E-PL9 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.

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.

The review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
