Olympus E-450 vs E-P1

The Olympus E-450 and the Olympus PEN E-P1 are two digital cameras that were announced, respectively, in March 2009 and June 2009. The E-450 is a DSLR, while the E-P1 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The E-450 has a resolution of 10 megapixels, whereas the E-P1 provides 12.2 MP.

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

Body comparison

An illustration of the physical size and weight of the Olympus E-450 and the Olympus E-P1 is provided 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 dimensions are rounded to the nearest millimeter.

The E-P1 can be obtained in three different colors (black, silver, white), while the E-450 is only available in black.

Compare E-450 versus E-P1 top
Comparison E-450 or E-P1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P1 is notably smaller (28 percent) than the Olympus E-450. Moreover, the E-P1 is markedly lighter (19 percent) than the E-450. In this context, it is worth noting that neither the E-450 nor the E-P1 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-450) and the Micro Four Thirds Lens Catalog (E-P1). Mirrorless cameras, such as the E-P1, 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 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.

Any camera decision will naturally be influenced heavily by the price. 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 38 percent) than the E-P1, 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Technology-wise, the E-P1 uses a more advanced image processing engine (TruePic V) than the E-450 (TruePic III+), with benefits for noise reduction, color accuracy, and processing speed.

Olympus E-450 and Olympus E-P1 sensor measures

While the two cameras under review share the same sensor size, the E-P1 offers a higher resolution of 12.2 megapixels, compared with 10 MP of the E-450. This megapixels advantage translates into a 11 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-P1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 4.74μm for the E-450). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

The resolution advantage of the Olympus E-P1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-P1 for good quality output (200 dots per inch) amounts to 20.2 x 15.1 inches or 51.2 x 38.4 cm, for very good quality (250 dpi) 16.1 x 12.1 inches or 41 x 30.7 cm, and for excellent quality (300 dpi) 13.4 x 10.1 inches or 34.1 x 25.6 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 Olympus E-450 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Olympus PEN E-P1 are ISO 100 to ISO 6400 (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.

E-450 versus E-P1 MP

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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-450 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Olympus E-450 and Olympus E-P1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The E-450 has one, while the E-P1 does not. While the built-in flash of the E-450 is not very powerful, it can at times be useful as a fill-in light.

The E-450 writes its imaging data to Compact Flash or xD Picture cards, while the E-P1 uses SDHC cards. The E-450 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P1 only has one slot.

Review summary

So how do things add up? Is there a clear favorite between the Olympus E-450 and the Olympus E-P1? Which camera is better? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Olympus E-450:

  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (500 versus 300) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • 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 (38 percent cheaper at launch).


Advantages of the Olympus PEN E-P1:

  • More detail: Has more megapixels (12.2 vs 10MP), which boosts linear resolution by 11%.
  • Better jpgs: Has a more modern image processing engine (TruePic V vs TruePic III+).
  • Broader imaging potential: Can capture not only stills but also 720/30p video.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
  • More compact: Is smaller (121x70mm vs 130x91mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 85g or 19 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.

If the number of relative strengths (bullet points above) is taken as a guide, the E-P1 emerges as the winner of the match-up (8 : 6 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.

E-450 06:08 E-P1

How about other alternatives? Do the specifications of the Olympus E-450 and the Olympus E-P1 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the E-450 or the E-P1 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

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.

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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
