Canon D30 versus Panasonic GX85

The Canon EOS-D30 and the Panasonic Lumix DMC-GX85 (labelled Panasonic GX80 in some countries) are two digital cameras that were officially introduced, respectively, in May 2000 and April 2016. The Canon D30 is a DSLR, while the GX85 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (Canon D30) and a Four Thirds (GX85) sensor. The Canon has a resolution of 3.1 megapixel, whereas the Panasonic provides 15.8 MP. 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: Canon D30 vs Panasonic GX85

The physical size and weight of the Canon D30 and the Panasonic GX85 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size 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 Canon D30 – represents 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 Panasonic GX85 is considerably smaller (46 percent) than the Canon D30. Moreover, the GX85 is substantially lighter (43 percent) than the Canon D30. In this context, it is worth noting that neither the Canon D30 nor the GX85 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (Canon D30) and the Micro Four Thirds Lens Catalog (GX85). Mirrorless cameras, such as the GX85, 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.

Concerning battery life, the Canon D30 gets 540 shots out of its BP-511 battery, while the GX85 can take 290 images on a single charge of its DMW-BLG10 power pack.

Any camera purchase will naturally be influenced heavily by the price. 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 GX85 was launched at a markedly lower price (by 73 percent) than the Canon D30, which puts it into a different 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.

 

Sensor comparison: Canon D30 vs Panasonic GX85

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon D30 features an APS-C sensor and the Panasonic GX85 a Four Thirds sensor. The sensor area in the GX85 is 31 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the Canon D30 has a native 3:2 aspect ratio, while the one in the GX85 offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon D30 and Panasonic GX85 sensor measures

Despite having a smaller sensor, the GX85 offers a higher resolution of 15.8 megapixel, compared with 3.1 MP of the Canon D30. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 10.29μm for the Canon D30). However, it should be noted that the GX85 is much more recent (by 15 years and 10 months) than the Canon D30, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the GX85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Many modern cameras are not only capable of taking still images, but can also record movies. The GX85 indeed provides for movie recording, while the Canon D30 does not. The highest resolution format that the GX85 can use is 4K/30p.

 

Feature comparison: Canon D30 vs Panasonic GX85

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GX85 has an electronic viewfinder (2765k dots), while the Canon D30 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 Canon D30 and Panasonic GX85 along with similar information for a selection of comparators.

One feature that is present on the Canon D30, but is missing on the GX85 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX85 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

The GX85 is a current model that online retailers, such as amazon, will have in stock. In contrast, the Canon D30 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the Canon D30 was succeeded by the Canon D60.

Review summary: Canon D30 vs Panasonic GX85

So how do things add up? Which of the two cameras – the Canon D30 or the Panasonic GX85 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Canon EOS-D30:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Longer lasting: Can take more shots (540 versus 290) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in May 2000).

ilogo

Arguments in favor of the Panasonic Lumix DMC-GX85:

  • More detail: Has more megapixels (15.8 vs 3.1MP), which boosts linear resolution by 121%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 114k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (8 vs 3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (122x71mm vs 150x107mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 324g or 43 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced into a lower priced category (73 percent cheaper at launch).
  • More modern: Reflects 15 years and 10 months of technical progress since the Canon D30 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the GX85 is the clear winner of the contest (16 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

Canon D30 05:16 GX85

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 Canon D30 or the GX85 handle or 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. This is where reviews by experts come in.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
