Olympus E-P1 versus Olympus E-P2

The Olympus PEN E-P1 and the Olympus PEN E-P2 are two enthusiast cameras that were announced, respectively, in June 2009 and November 2009. Both the E-P1 and the E-P2 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 12.2 megapixel. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Olympus E-P1 vs Olympus E-P2

The side-by-side display below illustrates the physical size and weight of the Olympus E-P1 and the Olympus E-P2. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the E-P1 – represents the basis for the calculations across all the size and weight measures).

In this particular case, the Olympus E-P1 and the Olympus E-P2 have exactly the same width and height, and, thus, have identically-sized bodies. Moreover, the two cameras also share the same weight. In this context, it is worth noting that neither the E-P1 nor the E-P2 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The two cameras under review were launched at the same price and fall into the same 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Olympus E-P1 vs Olympus E-P2

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies 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.

Olympus E-P1 and Olympus E-P2 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 12.2 megapixel. This similarity in sensor specs implies that both the E-P1 and the E-P2 have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-P2 is a somewhat more recent model (by 4 months) than the E-P1, and its sensor might have benefitted from technological advances during this time.

E-P1 versus E-P2 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (720/30p).

 

Feature comparison: Olympus E-P1 vs Olympus E-P2

Apart from body and sensor, cameras can and do differ across a range of features. The E-P1 and the E-P2 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the E-P2 can be equipped with an optional viewfinder – the VF-2. The adjacent table lists some of the other core features of the Olympus E-P1 and Olympus E-P2 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

Both the E-P1 and the E-P2 have been discontinued, but can regularly be found used on eBay. The E-P1 was replaced by the Olympus E-P2, while the E-P2 was followed by the Olympus E-P3.

Review summary: Olympus E-P1 vs Olympus E-P2

So what is the bottom line? Which of the two cameras – the Olympus E-P1 or the Olympus E-P2 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Olympus PEN E-P1:

  • More heavily discounted: Has been on the market for longer (launched in June 2009).


Advantages of the Olympus PEN E-P2:

  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • More modern: Was introduced somewhat (4 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the E-P2 comes out slightly ahead of the E-P1 (2 : 1 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.

E-P1 01:02 E-P2

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the E-P1 and the E-P2 in practical situations. 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. This is where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
