Olympus E-620 vs Panasonic G10
The Olympus E-620 and the Panasonic Lumix DMC-G10 are two digital cameras that were revealed to the public, respectively, in February 2009 and March 2010. The E-620 is a DSLR, while the G10 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Panasonic provides 12 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 E-620 and the Panasonic Lumix DMC-G10? 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.
The side-by-side display below illustrates the physical size and weight of the Olympus E-620 and the Panasonic G10. 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 measures 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 Panasonic G10 is notably smaller (15 percent) than the Olympus E-620. Moreover, the G10 is markedly lighter (26 percent) than the E-620. In this context, it is worth noting that neither the E-620 nor the G10 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-620) and the Micro Four Thirds Lens Catalog (G10). Mirrorless cameras, such as the G10, 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G10 was launched at a markedly lower price (by 29 percent) than the E-620, 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.
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. 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.
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, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
While the two cameras under review share the same sensor size, the E-620 offers a slightly higher resolution of 12.2 megapixels, compared with 12 MP of the G10. This megapixels advantage translates into a 0.8 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-620 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 4.33μm for the G10). Moreover, it should be noted that the G10 is a somewhat more recent model (by 1 year) than the E-620, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.
The Olympus E-620 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Panasonic Lumix DMC-G10 are ISO 100 to ISO 6400 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The G10 indeed provides for movie recording, while the E-620 does not. The highest resolution format that the G10 can use is 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G10 has an electronic viewfinder (202k dots), while the E-620 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the G10 offers a wider field of view (100%) than the one in the E-620 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the G10 has a higher magnification (0.52x vs 0.48x), 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 Olympus E-620, the Panasonic G10, and comparable cameras.

One feature that differentiates the E-620 and the G10 is in-body image stabilization (IBIS). The E-620 reduces the risk of handshake-induced blur with all attached lenses, while the G10 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.The E-620 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 G10 does not have a selfie-screen.
The E-620 writes its imaging data to Compact Flash or xD Picture cards, while the G10 uses SDXC cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G10 only has one slot.
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 E-620 and Panasonic Lumix DMC-G10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-620 and the G10 have been discontinued, but can regularly be found used on eBay. The E-620 was replaced by the Olympus E-600, while the G10 was followed by the Panasonic G3. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Panasonic websites.
So what conclusions can be drawn? Is there a clear favorite between the Olympus E-620 and the Panasonic G10? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Olympus E-620:
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (4 vs 2.6 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (500 versus 380) on a single battery charge.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been on the market for longer (launched in February 2009).
Reasons to prefer the Panasonic Lumix DMC-G10:
- Broader imaging potential: Can capture not only stills but also 720/30p video.
- More framing info: Has an electronic viewfinder that displays shooting data.
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.52x vs 0.48x).
- 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 (460k vs 230k dots).
- More compact: Is smaller (124x84mm vs 130x94mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 133g or 26 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the G10 emerges as the winner of the match-up (11 : 9 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Olympus E-620 and the Panasonic G10 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-620 or the G10. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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.
Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
