Olympus E-P1 vs Ricoh GR

The Olympus PEN E-P1 and the Ricoh GR are two digital cameras that were revealed to the public, respectively, in June 2009 and April 2013. The E-P1 is a mirrorless interchangeable lens camera, while the GR is a fixed lens compact. The cameras are based on a Four Thirds (E-P1) and an APS-C (GR) sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Ricoh provides 16.1 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 Olympus PEN E-P1 and the Ricoh GR? 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: Olympus E-P1 vs Ricoh GR

The physical size and weight of the Olympus E-P1 and the Ricoh GR 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-P1 can be obtained in three different colors (black, silver, white), while the GR is only available in black.

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

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR is notably smaller (16 percent) than the Olympus E-P1. In this context, it is worth noting that neither the E-P1 nor the GR are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR has a lens built in, whereas the E-P1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-P1 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-P1 gets 300 shots out of its BLS-1 battery, while the GR can take 290 images on a single charge of its DB65 power pack. The power pack in the GR can be charged via the USB port, which can be very convenient when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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. 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: Olympus E-P1 vs Ricoh GR

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 Olympus E-P1 features a Four Thirds sensor and the Ricoh GR an APS-C sensor. The sensor area in the GR is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-P1 has a native 4:3 aspect ratio, while the one in the GR offers a 3:2 aspect.

Olympus E-P1 and Ricoh GR sensor measures

With 16.1MP, the GR offers a higher resolution than the E-P1 (12.2MP), but the GR nevertheless has larger individual pixels (pixel pitch of 4.79μm versus 4.29μm for the E-P1) due to its larger sensor. Moreover, the GR is a much more recent model (by 3 years and 10 months) than the E-P1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the GR has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Ricoh GR implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inch or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inch or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inch or 41.7 x 27.6 cm. The corresponding values for the Olympus E-P1 are 20.2 x 15.1 inch or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inch or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inch or 34.1 x 25.6 cm for excellent quality prints.

The Olympus PEN E-P1 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Ricoh GR are ISO 100 to ISO 25600 (no boost).

E-P1 versus GR MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the GR offers substantially better image quality than the E-P1 (overall score 23 points higher). The advantage is based on 2.2 bits higher color depth, 3.1 EV in additional dynamic range, and 0.9 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GR provides a better video resolution than the E-P1. It can shoot movie footage at 1080/30p, while the Olympus is limited to 720/30p.

 

Feature comparison: Olympus E-P1 vs Ricoh GR

Beyond body and sensor, cameras can and do differ across a range of features. The E-P1 and the GR 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 GR can be equipped with an optional viewfinder – the GV-1.

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

The Ricoh GR 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 E-P1 writes its imaging data to SDHC cards, while the GR uses SDXC cards. The GR supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-P1 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Olympus E-P1 vs Ricoh GR

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 Olympus PEN E-P1 and Ricoh GR and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-P1 and the GR have been discontinued, but can regularly be found used on eBay. The E-P1 was replaced by the Olympus E-P2, while the GR was followed by the Ricoh GR II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Ricoh websites.


Review summary: Olympus E-P1 vs Ricoh GR

So how do things add up? Which of the two cameras – the Olympus E-P1 or the Ricoh GR – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Olympus PEN E-P1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More heavily discounted: Has been available for much longer (launched in June 2009).

ilogo

Reasons to prefer the Ricoh GR:

  • More detail: Has more megapixels (16.1 vs 12.2MP), which boosts linear resolution by 17%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (23 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.9 stops ISO advantage).
  • Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 230k dots).
  • Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Ready to shoot: Has an integrated lens, whereas the E-P1 necessitates an extra lens.
  • More compact: Is smaller (117x61mm vs 121x70mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the E-P1).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 3 years and 10 months of technical progress since the E-P1 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the GR is the clear winner of the contest (17 : 4 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-P1 04:17 GR

How about other alternatives? Do the specifications of the Olympus E-P1 and the Ricoh GR place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-P1 or the GR. 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: Olympus E-P1 vs Ricoh GR

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
