Canon T4i vs Olympus E-330

The Canon EOS Rebel T4i (called Canon 650D in some regions) and the Olympus Evolt E-330 are two digital cameras that were revealed to the public, respectively, in June 2012 and January 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T4i) and a Four Thirds (E-330) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Olympus provides 7.4 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 Rebel T4i and the Olympus Evolt E-330? 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 T4i and the Olympus E-330. 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 dimensions are rounded to the nearest millimeter.

Compare T4i versus E-330 top
Comparison T4i or E-330 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-330 is notably smaller (8 percent) than the Canon T4i. However, the E-330 is markedly heavier (11 percent) than the T4i. In this context, it is worth noting that neither the T4i nor the E-330 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 (T4i) and the Four Thirds Lens Catalog (E-330).

Concerning battery life, the T4i gets 440 shots out of its LP-E8 battery, while the E-330 can take 750 images on a single charge of its BLM-1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 T4i was launched at a somewhat lower price (by 15 percent) than the E-330, which makes it more attractive for photographers on a tight budget. 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. 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. 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 T4i features an APS-C sensor and the Olympus E-330 a Four Thirds sensor. The sensor area in the E-330 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 T4i has a native 3:2 aspect ratio, while the one in the E-330 offers a 4:3 aspect.

Canon T4i and Olympus E-330 sensor measures

With 17.9MP, the T4i offers a higher resolution than the E-330 (7.4MP), but the T4i has smaller individual pixels (pixel pitch of 4.31μm versus 5.51μm for the E-330). However, the T4i is a much more recent model (by 6 years and 4 months) than the E-330, 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 T4i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T4i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Olympus E-330 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 cm for excellent quality prints.

The T4i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS Rebel T4i 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 Evolt E-330 are ISO 100 to ISO 400, with the possibility to increase the ISO range to 100-1600.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The T4i indeed provides movie recording capabilities, while the E-330 does not. The highest resolution format that the T4i can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The T4i and the E-330 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 T4i has a higher magnification than the one of the E-330 (0.53x vs 0.47x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon T4i, the Olympus E-330, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T4i has a touchscreen, while the E-330 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The T4i has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the E-330 does not have a selfie-screen.

The T4i writes its imaging data to SDXC cards, while the E-330 uses Compact Flash or xD Picture cards. The E-330 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T4i 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 Rebel T4i and Olympus Evolt E-330 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the T4i and the E-330 have been discontinued, but can regularly be found used on eBay. The T4i was replaced by the Canon T5i, while the E-330 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Olympus websites.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon T4i and the Olympus E-330? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Canon EOS Rebel T4i:

  • More detail: Offers more megapixels (17.9 vs 7.4MP) with a 59% 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.
  • 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 (0.53x vs 0.47x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") 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 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 62g or 10 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (15 percent cheaper at launch).
  • More modern: Reflects 6 years and 4 months of technical progress since the E-330 launch.

ilogo

Reasons to prefer the Olympus Evolt E-330:

  • Longer lasting: Gets more shots (750 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 heavily discounted: Has been around for much longer (launched in January 2006).

If the count of individual advantages (bullet points above) is taken as a guide, the T4i is the clear winner of the match-up (17 : 3 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

T4i 17:03 E-330

How about other alternatives? Do the specifications of the Canon T4i and the Olympus E-330 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 T4i or the E-330 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 where reviews by experts come in. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
