Canon 750D vs Olympus E-450

The Canon EOS 750D (called Canon T6i in some regions) and the Olympus E-450 are two digital cameras that were officially introduced, respectively, in February 2015 and March 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (750D) and a Four Thirds (E-450) sensor. The Canon has a resolution of 24 megapixels, whereas the Olympus provides 10 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 750D and the Olympus E-450? 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 side-by-side display below illustrates the physical size and weight of the Canon 750D and the Olympus E-450. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. 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 Olympus E-450 is notably smaller (11 percent) than the Canon 750D. Moreover, the E-450 is markedly lighter (21 percent) than the 750D. In this context, it is worth noting that neither the 750D nor the E-450 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 (750D) and the Four Thirds Lens Catalog (E-450).

Concerning battery life, the 750D gets 440 shots out of its LP-E17 battery, while the E-450 can take 500 images on a single charge of its BLS-1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The E-450 was launched at a markedly lower price (by 33 percent) than the 750D, 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 750D features an APS-C sensor and the Olympus E-450 a Four Thirds sensor. The sensor area in the E-450 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 750D has a native 3:2 aspect ratio, while the one in the E-450 offers a 4:3 aspect.

With 24MP, the 750D offers a higher resolution than the E-450 (10MP), but the 750D has smaller individual pixels (pixel pitch of 3.72μm versus 4.74μm for the E-450). However, the 750D is a much more recent model (by 5 years and 10 months) than the E-450, 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 750D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 750D 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 Olympus E-450 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The 750D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 750D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Olympus E-450 are ISO 100 to ISO 1600 (no boost).

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 review, the 750D provides substantially higher image quality than the E-450, with an overall score that is 15 points higher. This advantage is based on 1.2 bits higher color depth, 1.5 EV in additional dynamic range, and 0.8 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The 750D indeed provides movie recording capabilities, while the E-450 does not. The highest resolution format that the 750D can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 750D and the E-450 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the 750D has a higher magnification than the one of the E-450 (0.51x vs 0.46x), 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 750D and Olympus E-450 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 750D has a touchscreen, while the E-450 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The 750D writes its imaging data to SDXC cards, while the E-450 uses Compact Flash or xD Picture cards. The E-450 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 750D only has one slot.

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 750D and Olympus E-450 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 750D offers wifi support, while the E-450 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the 750D and the E-450 have been discontinued, but can regularly be found used on ebay. The 750D was replaced by the Canon 800D, while the E-450 does not have a direct successor. Further information on the features and operation of the 750D and E-450 can be found, respectively, in the Canon 750D Manual (free pdf) or the online Olympus E-450 Manual.

Review summary

So what conclusions can be drawn? Is the Canon 750D better than the Olympus E-450 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS 750D:

• More detail: Offers more megapixels (24 vs 10MP) with a 58% higher linear resolution.
• Better image quality: Scores substantially higher (15 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.2 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (1.5 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.51x vs 0.46x).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 215k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (5 vs 3.5 flaps/sec) to capture the decisive moment.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More modern: Reflects 5 years and 10 months of technical progress since the E-450 launch.

Reasons to prefer the Olympus E-450:

• More compact: Is smaller (130x91mm vs 132x101mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 115g or 21 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (500 versus 440) out of a single battery charge.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
• 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 750D is the clear winner of the match-up (17 : 6 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 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 750D and the Olympus E-450 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 750D or the E-450 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 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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
