Olympus E-1 vs Panasonic FZ2500
The Olympus E-1 and the Panasonic Lumix DMC-FZ2500 (labelled Panasonic FZ2000 in some countries) are two digital cameras that were announced, respectively, in June 2003 and September 2016. The E-1 is a DSLR, while the FZ2500 is a fixed lens compact. The cameras are based on a Four Thirds (E-1) and an one-inch (FZ2500) sensor. The Olympus has a resolution of 4.9 megapixels, whereas the Panasonic provides 20 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-1 and the Panasonic Lumix DMC-FZ2500? 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.
An illustration of the physical size and weight of the Olympus E-1 and the Panasonic FZ2500 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic FZ2500 is somewhat smaller (4 percent) than the Olympus E-1. It is worth mentioning in this context that the E-1 is splash and dust resistant, while the FZ2500 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the FZ2500 has a lens built in, whereas the E-1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-1 and their specifications in the Four Thirds Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The FZ2500 was launched at a lower price than the E-1, despite having a lens built in. 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. 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 tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-1 features a Four Thirds sensor and the Panasonic FZ2500 an one-inch sensor. The sensor area in the FZ2500 is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the E-1 has a native 4:3 aspect ratio, while the one in the FZ2500 offers a 3:2 aspect.
Despite having a smaller sensor, the FZ2500 offers a higher resolution of 20 megapixels, compared with 4.9 MP of the E-1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 6.78μm for the E-1). However, it should be noted that the FZ2500 is much more recent (by 13 years and 2 months) than the E-1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Panasonic FZ2500 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the FZ2500 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 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 DMC-FZ2500 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
In terms of underlying technology, the E-1 is build around a CCD sensor, while the FZ2500 uses a BSI-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.
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The FZ2500 indeed provides for movie recording, while the E-1 does not. The highest resolution format that the FZ2500 can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the FZ2500 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 FZ2500 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.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
One feature that is present on the E-1, but is missing on the FZ2500 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 FZ2500 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 FZ2500 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 FZ2500 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 FZ2500 uses SDXC cards. The E-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the FZ2500 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-1 and Panasonic Lumix DMC-FZ2500 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the FZ2500 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 FZ2500) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The FZ2500 is a recent model that features in the current product line-up of Panasonic. In contrast, the E-1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-1 was succeeded by the Olympus E-3. Further information on the features and operation of the E-1 and FZ2500 can be found, respectively, in the Olympus E-1 Manual (free pdf) or the online Panasonic FZ2500 Manual.
So how do things add up? Is there a clear favorite between the Olympus E-1 and the Panasonic FZ2500? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Olympus E-1:

If the number of relative strengths (bullet points above) is taken as a guide, the FZ2500 is the clear winner of the contest (18 : 8 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.
How about other alternatives? Do the specifications of the Olympus E-1 and the Panasonic FZ2500 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the E-1 and the FZ2500 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 hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
