Olympus E-M1 II vs Panasonic TZ100
The Olympus OM-D E-M1 Mark II and the Panasonic Lumix DMC-TZ100 (labelled Panasonic ZS100 in some countries) are two digital cameras that were announced, respectively, in September 2016 and January 2016. The E-M1 II is a mirrorless interchangeable lens camera, while the TZ100 is a fixed lens compact. The cameras are based on a Four Thirds (E-M1 II) and an one-inch (TZ100) sensor. The Olympus has a resolution of 20.2 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 OM-D E-M1 Mark II 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.
An illustration of the physical size and weight of the Olympus E-M1 II and the Panasonic TZ100 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 width, height and depth dimensions are rounded to the nearest millimeter.
The TZ100 can be obtained in two different colors (black, silver), while the E-M1 II is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic TZ100 is considerably smaller (41 percent) than the Olympus E-M1 II. It is worth mentioning in this context that the E-M1 II is splash and dust resistant, while the TZ100 does not feature any corresponding weather-sealing.
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-M1 II 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-M1 II and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the E-M1 II gets 440 shots out of its BLH-1 battery, while the TZ100 can take 300 images on a single charge of its 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. 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 TZ100 was launched at a lower price than the E-M1 II, 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.
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. 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 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-M1 II 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-M1 II has a native 4:3 aspect ratio, while the one in the TZ100 offers a 3:2 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 20.2MP, the E-M1 II offers a slightly higher resolution than the TZ100 (20MP), but the E-M1 II nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the TZ100) due to its larger sensor. Moreover, the E-M1 II is a somewhat more recent model (by 8 months) than the TZ100, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the E-M1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The E-M1 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the TZ100, the E-M1 II has the capacity to capture high quality composite images (50MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Olympus OM-D E-M1 Mark II has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 64-25600. 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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under review, the E-M1 II has a notably higher overall DXO score than the TZ100 (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 0.3 EV in additional dynamic range, and 1.2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/30p).
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the E-M1 II offers a substantially higher resolution than the one in the TZ100 (2360k vs 1166k dots). The following table reports on some other key feature differences and similarities of the Olympus E-M1 II, the Panasonic TZ100, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The TZ100 has one, while the E-M1 II does not. While the built-in flash of the TZ100 is not very powerful, it can at times be useful as a fill-in light.The E-M1 II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the TZ100 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, both cameras under consideration feature an 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 Olympus E-M1 II and the Panasonic TZ100 both have 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.
Concerning the storage of imaging data, both the E-M1 II and the TZ100 write their files to SDXC cards. The E-M1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the TZ100 only has one slot. The E-M1 II supports UHS-II cards (on its first slot), while the TZ100 can use UHS-I cards.
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 OM-D E-M1 Mark II 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-M1 II has a hotshoe, while the TZ100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Studio photographers will appreciate that the Olympus E-M1 II (unlike the TZ100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The E-M1 II is a recent model that features in the current product line-up of Olympus. In contrast, the TZ100 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the TZ100 was succeeded by the Panasonic TZ200. 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.
So what conclusions can be drawn? Which of the two cameras – the Olympus E-M1 II or the Panasonic TZ100 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Olympus OM-D E-M1 Mark II:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better image quality: Scores markedly higher (10 points) in the DXO overall assessment.

Arguments in favor of the Panasonic Lumix DMC-TZ100:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Ready to shoot: Has an integrated lens, whereas the E-M1 II necessitates an extra lens.
- More compact: Is smaller (111x65mm vs 134x91mm) 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-M1 II).
- Easier travel charging: Can be conveniently charged via its USB port.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been on the market for longer (launched in January 2016).
If the count of individual advantages (bullet points above) is taken as a guide, the E-M1 II is the clear winner of the match-up (22 : 8 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 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-M1 II 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the E-M1 II and the TZ100 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
