Olympus E-PL1 vs Panasonic TZ90
The Olympus PEN E-PL1 and the Panasonic Lumix DC-TZ90 (labelled Panasonic ZS70 in some countries) are two digital cameras that were announced, respectively, in February 2010 and April 2017. The E-PL1 is a mirrorless interchangeable lens camera, while the TZ90 is a fixed lens compact. The cameras are based on a Four Thirds (E-PL1) and a 1/2.3-inch (TZ90) sensor. The Olympus has a resolution of 12.2 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 PEN E-PL1 and the Panasonic Lumix DC-TZ90? 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-PL1 and the Panasonic TZ90 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The E-PL1 can be obtained in four different colors (black, blue, yellow, white), while the TZ90 is available in two color-versions (black, silver).



If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic TZ90 is notably smaller (9 percent) than the Olympus E-PL1. In this context, it is worth noting that neither the E-PL1 nor the TZ90 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TZ90 has a lens built in, whereas the E-PL1 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-PL1 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the E-PL1 gets 290 shots out of its Olympus BLS-1 battery, while the TZ90 can take 380 images on a single charge of its Panasonic DMW-BLG10 power pack. The power pack in the TZ90 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. 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.

The price is, of course, an important factor in any camera decision. 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 TZ90 was launched at a lower price than the E-PL1, despite having a lens built in. 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 imaging sensor is a crucial determinant 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-PL1 features a Four Thirds sensor and the Panasonic TZ90 a 1/2.3-inch sensor. The sensor area in the TZ90 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the TZ90 offers a higher resolution of 20.2 megapixels, compared with 12.2 MP of the E-PL1. 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 1.18μm versus 4.29μm for the E-PL1). However, it should be noted that the TZ90 is much more recent (by 7 years and 2 months) than the E-PL1, 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 TZ90 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Panasonic TZ90 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TZ90 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-PL1 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The Olympus PEN E-PL1 has a native sensitivity range from ISO 200 to ISO 3200. The corresponding ISO settings for the Panasonic Lumix DC-TZ90 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.
In terms of underlying technology, the E-PL1 is build around a CMOS sensor, while the TZ90 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 determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the E-PL1 provides substantially higher image quality than the TZ90, with an overall score that is 18 points higher. This advantage is based on 2.4 bits higher color depth, 0.5 EV of lower dynamic range, and 2.2 stops in additional low light sensitivity.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the TZ90 provides a better video resolution than the E-PL1. It can shoot movie footage at 4K/30p, while the Olympus is limited to 720/30p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the TZ90 has an electronic viewfinder (1166k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PL1 relies on live view and the rear LCD for framing. That said, the E-PL1 can be equipped with an optional viewfinder – the VF-2. The table below summarizes some of the other core capabilities of the Olympus E-PL1 and Panasonic TZ90 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 TZ90 has a touchscreen, while the E-PL1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The TZ90 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-PL1 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 TZ90 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 E-PL1 writes its imaging data to SDHC cards, while the TZ90 uses SDXC cards. The TZ90 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-PL1 cannot take advantage of Ultra High Speed SD cards.
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 PEN E-PL1 and Panasonic Lumix DC-TZ90 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PL1 has a hotshoe, while the TZ90 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the E-PL1 and the TZ90 have been discontinued, but can regularly be found used on ebay. The E-PL1 was replaced by the Olympus E-PL2, while the TZ90 was followed by the Panasonic TZ95. Further information on the features and operation of the E-PL1 and TZ90 can be found, respectively, in the Olympus E-PL1 Manual (free pdf) or the online Panasonic TZ90 Manual.
Review summary
So how do things add up? Is the Olympus E-PL1 better than the Panasonic TZ90 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Olympus PEN E-PL1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Scores substantially higher (18 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (2.4 bits more color depth).
- Better low-light sensitivity: Requires less light for good images (2.2 stops ISO advantage).
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been available for much longer (launched in February 2010).

Reasons to prefer the Panasonic Lumix DC-TZ90:
- More detail: Has more megapixels (20.2 vs 12.2MP), which boosts linear resolution by 29%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- 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 (1040k vs 230k 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.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Ready to shoot: Has an integrated lens, whereas the E-PL1 necessitates an extra lens.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the E-PL1).
- Longer lasting: Gets more shots (380 versus 290) out of a single battery charge.
- Easier travel charging: Can be conveniently charged via its USB port.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 7 years and 2 months of technical progress since the E-PL1 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the TZ90 is the clear winner of the contest (19 : 7 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 before making a camera decision. 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-PL1 and the Panasonic TZ90 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-PL1 or the TZ90. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
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 ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
