Panasonic G10 versus Olympus E-450

The Panasonic Lumix DMC-G10 and the Olympus E-450 are two digital cameras that were revealed to the public, respectively, in March 2010 and March 2009. The Lumix G10 is a mirrorless interchangeable lens camera, while the E-450 is a DSLR. Both cameras are equipped with a Four Thirds sensor. The Panasonic has a resolution of 12 megapixel, whereas the Olympus provides 10 MP.

Body comparison

An illustration of the physical size and weight of the Panasonic G10 and the Olympus E-450 is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the Lumix G10 – represents the basis or 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-450 is notably larger (14 percent) than the Panasonic G10. Moreover, the E-450 is markedly heavier (13 percent) than the Lumix G10. In this context, it is worth noting that neither the Lumix G10 nor the E-450 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 find an overview of optics for the two cameras in the Micro Four Thirds Lens Catalog (Lumix G10) and the Four Thirds Lens Catalog (E-450). Mirrorless cameras, such as the Panasonic G10, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The two cameras under review were launched at the same price and fall into the same market segment. 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. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 are more costly to manufacture and tent 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.

Panasonic G10 and Olympus E-450 sensor measures
Sensor size

While the two cameras under review share the same sensor size, the Lumix G10 offers a higher resolution of 12 megapixel, compared with 10 MP of the E-450. This megapixel advantage translates into a 10 percent gain in linear resolution. On the other hand, these sensor specs imply that the Lumix G10 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.33μm versus 4.74μm for the E-450). In this context, it should be noted, however, that the Lumix G10 is a somewhat more recent model (by 11 months) than the E-450, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most 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"). Of the two cameras under consideration, the E-450 has a markedly higher DXO score than the Lumix G10 (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.3 bits higher color depth, 0.4 EV in additional dynamic range, and 0.3 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 can also record movies. The Lumix G10 indeed provides movie recording capabilities, while the E-450 does not. The highest resolution format that the Lumix G10 can use is 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Lumix G10 has an electronic viewfinder (202k dots), while the E-450 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 adjacent table lists some of the other core features of the Panasonic G10 and Olympus E-450 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the Lumix G10 and the E-450 have been discontinued, but can regularly be found used on ebay. The Lumix G10 was replaced by the Panasonic G3, while the E-450 does not have a direct successor.

Summary

So how do things add up? Is the Panasonic G10 better than the Olympus E-450 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


logo checkmark

Arguments in favor of the Panasonic Lumix DMC-G10:

  • More detail: Offers more megapixels (12 vs 10MP) with a 10% higher linear resolution.
  • Broader imaging potential: Can record not only still images but also 720/30p movies.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • 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 215k dots).
  • More compact: Is smaller (124x84mm vs 130x91mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 52g or 12 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • More modern: Is somewhat more recent (announced 11 months after the E-450).

Advantages of the Olympus E-450:

  • Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Faster burst: Shoots at higher frequency (3.5 vs 2.6 flaps/sec) to capture the decisive moment.
  • More heavily discounted: Has been on the market for longer (launched in March 2010).

If the number of relative strengths (bullet points above) is taken as a guide, the Lumix G10 is the clear winner of the match-up (9 : 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.

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 Lumix G10 and the E-450 in practical situations. 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 why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
