Olympus E-PL1 vs Panasonic TZ100

The Olympus PEN E-PL1 and the Panasonic Lumix DMC-TZ100 (labelled Panasonic ZS100 in some countries) are two digital cameras that were announced, respectively, in February 2010 and January 2016. The E-PL1 is a mirrorless interchangeable lens camera, while the TZ100 is a fixed lens compact. The cameras are based on a Four Thirds (E-PL1) and an one-inch (TZ100) sensor. The Olympus has a resolution of 12.2 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 PEN E-PL1 and the Panasonic Lumix DMC-TZ100? 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

The side-by-side display below illustrates the physical size and weight of the Olympus E-PL1 and the Panasonic TZ100. 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.

The E-PL1 can be obtained in four different colors (black, blue, yellow, white), while the TZ100 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 TZ100 is notably smaller (13 percent) than the Olympus E-PL1. In this context, it is worth noting that neither the E-PL1 nor the TZ100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TZ100 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 TZ100 can take 300 images on a single charge of its Panasonic DMW-BLG10 power pack. The power pack in the TZ100 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. 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.

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. 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 size of the sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-PL1 features a Four Thirds sensor and the Panasonic TZ100 an one-inch sensor. The sensor area in the TZ100 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-PL1 has a native 4:3 aspect ratio, while the one in the TZ100 offers a 3:2 aspect.

Despite having a smaller sensor, the TZ100 offers a higher resolution of 20 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 2.41μm versus 4.29μm for the E-PL1). However, it should be noted that the TZ100 is much more recent (by 5 years and 11 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.

The resolution advantage of the Panasonic TZ100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TZ100 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-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 DMC-TZ100 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the TZ100 offers substantially better image quality than the E-PL1 (overall score 16 points higher). The advantage is based on 1.3 bits higher color depth, 2.4 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the TZ100 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

Apart from body and sensor, cameras can and do differ across a range of features. For example, the TZ100 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 TZ100 in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The TZ100 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 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 TZ100 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 TZ100 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-PL1 writes its imaging data to SDHC cards, while the TZ100 uses SDXC cards. The TZ100 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 DMC-TZ100 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 TZ100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the E-PL1 and the TZ100 have been discontinued, but can regularly be found used on ebay. The E-PL1 was replaced by the Olympus E-PL2, while the TZ100 was followed by the Panasonic TZ200. Further information on the features and operation of the E-PL1 and TZ100 can be found, respectively, in the Olympus E-PL1 Manual (free pdf) or the online Panasonic TZ100 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Olympus E-PL1 and the Panasonic TZ100? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Olympus PEN E-PL1:

• 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).

Advantages of the Panasonic Lumix DMC-TZ100:

• More detail: Has more megapixels (20 vs 12.2MP), which boosts linear resolution by 30%.
• Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (2.4 EV of extra DR).
• 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).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• 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.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has an integrated lens, whereas the E-PL1 necessitates an extra lens.
• More compact: Is smaller (111x65mm vs 115x72mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the E-PL1).
• 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 modern: Reflects 5 years and 11 months of technical progress since the E-PL1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the TZ100 is the clear winner of the contest (19 : 3 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. 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.

How about other alternatives? Do the specifications of the Olympus E-PL1 and the Panasonic TZ100 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-PL1 or the TZ100. 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 where reviews by experts come in. 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.

The review scores listed above should be treated with care, 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 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.
