Olympus E-1 vs Panasonic G90

The Olympus E-1 and the Panasonic Lumix DC-G90 (labelled Panasonic G95 in some countries) are two digital cameras that were revealed to the public, respectively, in June 2003 and April 2019. The E-1 is a DSLR, while the G90 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The Olympus has a resolution of 4.9 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.

Body comparison

An illustration of the physical size and weight of the Olympus E-1 and the Panasonic G90 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Size Olympus E-1 vs Panasonic G90
Compare E-1 versus G90 top
Comparison E-1 or G90 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G90 is notably smaller (17 percent) than the Olympus E-1. Moreover, the G90 is markedly lighter (27 percent) than the E-1. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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-1) and the Micro Four Thirds Lens Catalog (G90). Mirrorless cameras, such as the G90, 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-1 gets 750 shots out of its Olympus BLM-1 battery, while the G90 can take 290 images on a single charge of its Panasonic DMW-BLC12 power pack. The power pack in the G90 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 G90 was launched at a markedly lower price (by 41 percent) than the E-1, 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

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 associated with larger, more expensive camera bodies 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.

Olympus E-1 and Panasonic G90 sensor measures

While the two cameras under review share the same sensor size, the G90 offers a higher resolution of 20.2 megapixels, compared with 4.9 MP of the E-1. This megapixels advantage translates into a 103 percent gain in linear resolution. On the other hand, these sensor specs imply that the G90 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 6.78μm for the E-1). However, it should be noted that the G90 is much more recent (by 15 years and 9 months) than the E-1, 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 G90 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic G90 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G90 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-1 are 12.8 x 9.6 inches or 32.5 x 24.4 cm for good quality, 10.2 x 7.7 inches or 26 x 19.5 cm for very good quality, and 8.5 x 6.4 inches or 21.7 x 16.3 cm for excellent quality prints.

The Olympus E-1 has a native sensitivity range from ISO 100 to ISO 800, which can be extended to ISO 100-3200. The corresponding ISO settings for the Panasonic Lumix DC-G90 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the E-1 is build around a CCD sensor, while the G90 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

E-1 versus G90 MP

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G90 has an electronic viewfinder (2360k dots), while the E-1 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the G90 has a higher magnification than the one of the E-1 (0.74x vs 0.48x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Olympus E-1 and Panasonic G90 along with similar information for a selection of comparators.

One feature that is present on the E-1, but is missing on the G90 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 G90 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the E-1 does not have a selfie-screen.

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 G90 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 G90 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-1 writes its imaging data to Compact Flash or xD Picture cards, while the G90 uses SDXC cards. The E-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G90 only has one slot.

It is notable that the G90 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-1 does not provide wifi capability.

Studio photographers will appreciate that the Olympus E-1 (unlike the G90) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-1 and the G90 have been discontinued, but can regularly be found used on ebay. The E-1 was replaced by the Olympus E-3, while the G90 does not have a direct successor. Further information on the features and operation of the E-1 and G90 can be found, respectively, in the Olympus E-1 Manual (free pdf) or the online Panasonic G90 Manual.

  • 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 (750 versus 290) on a single battery charge.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • 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 June 2003).

ilogo

Advantages of the Panasonic Lumix DC-G90:

  • More detail: Has more megapixels (20.2 vs 4.9MP), which boosts linear resolution by 103%.
  • 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 viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.48x).
  • 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 swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (9 vs 3 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 (130x94mm vs 141x104mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 202g or 27 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 fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • 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 affordable: Was introduced into a lower priced category (41 percent cheaper at launch).
  • More modern: Reflects 15 years and 9 months of technical progress since the E-1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the G90 is the clear winner of the contest (23 : 7 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-1 07:23 G90

How about other alternatives? Do the specifications of the Olympus E-1 and the Panasonic G90 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 incomplete and does no justice, for example, to the way the E-1 or the G90 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
