Olympus E-300 vs Panasonic GX9

The Olympus Evolt E-300 and the Panasonic Lumix DC-GX9 are two digital cameras that were officially introduced, respectively, in September 2004 and February 2018. The E-300 is a DSLR, while the GX9 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The Olympus has a resolution of 8 megapixels, whereas the Panasonic provides 20.2 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 Evolt E-300 and the Panasonic Lumix DC-GX9? 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

An illustration of the physical size and weight of the Olympus E-300 and the Panasonic GX9 is provided 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 width, height and depth measures are rounded to the nearest millimeter.

The GX9 can be obtained in two different colors (black, silver), while the E-300 is only available in black.

Compare E-300 versus GX9 top
Comparison E-300 or GX9 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX9 is notably smaller (29 percent) than the Olympus E-300. Moreover, the GX9 is substantially lighter (35 percent) than the E-300. In this context, it is worth noting that neither the E-300 nor the GX9 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-300) and the Micro Four Thirds Lens Catalog (GX9). Mirrorless cameras, such as the GX9, 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 E-300 gets 750 shots out of its BLM-1 battery, while the GX9 can take 260 images on a single charge of its DMW-BLG10 power pack. The power pack in the GX9 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-300 was somewhat cheaper (by 6 percent) than the GX9 at launch, but both cameras fall into the same price category. 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

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.

In terms of underlying technology, both cameras are build around CMOS sensors.

Olympus E-300 and Panasonic GX9 sensor measures

While the two cameras under review share the same sensor size, the GX9 offers a higher resolution of 20.2 megapixels, compared with 8 MP of the E-300. This megapixels advantage translates into a 59 percent gain in linear resolution. On the other hand, these sensor specs imply that the GX9 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 5.30μm for the E-300). However, it should be noted that the GX9 is much more recent (by 13 years and 4 months) than the E-300, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the GX9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic GX9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX9 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Olympus E-300 are 16.3 x 12.2 inches or 41.5 x 31.1 cm for good quality, 13.1 x 9.8 inches or 33.2 x 24.9 cm for very good quality, and 10.9 x 8.2 inches or 27.6 x 20.7 cm for excellent quality prints.

The Olympus Evolt E-300 has a native sensitivity range from ISO 100 to ISO 400, which can be extended to ISO 100-1600. The corresponding ISO settings for the Panasonic Lumix DC-GX9 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GX9 indeed provides for movie recording, while the E-300 does not. The highest resolution format that the GX9 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX9 has an electronic viewfinder (2760k dots), while the E-300 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 GX9 offers a wider field of view (100%) than the one in the E-300 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the GX9 has a higher magnification (0.70x vs 0.5x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Olympus E-300 and Panasonic GX9 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX9 has a touchscreen, while the E-300 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GX9 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Panasonic GX9 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-300 writes its imaging data to Compact Flash or xD Picture cards, while the GX9 uses SDXC cards. The E-300 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GX9 only has one slot.

Connectivity comparison

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 Evolt E-300 and Panasonic Lumix DC-GX9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX9 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-300 does not provide wifi capability.

The GX9 is a recent model that features in the current product line-up of Panasonic. In contrast, the E-300 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-300 was succeeded by the Olympus E-330. 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.

Review summary

So what is the bottom line? Which of the two cameras – the Olympus E-300 or the Panasonic GX9 – 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

Reasons to prefer the Olympus Evolt E-300:

  • 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.
  • Longer lasting: Can take more shots (750 versus 260) on a single battery charge.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been available for much longer (launched in September 2004).

ilogo

Advantages of the Panasonic Lumix DC-GX9:

  • More detail: Has more megapixels (20.2 vs 8MP), which boosts linear resolution by 59%.
  • 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.
  • 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 (0.70x vs 0.5x).
  • 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 (1240k vs 134k 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 (9 vs 2.5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (124x72mm vs 147x85mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 217g or 35 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 13 years and 4 months of technical progress since the E-300 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the GX9 is the clear winner of the contest (21 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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-300 05:21 GX9

How about other alternatives? Do the specifications of the Olympus E-300 and the Panasonic GX9 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 says little about, for example, the shooting experience and imaging performance of the E-300 and the GX9 in practical situations. 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

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.
