Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus XZ-1 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 physical size and weight of the Olympus XZ-1 and the Panasonic TZ100 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The XZ-1 can be obtained in two different colors (black, white), while the TZ100 is also available in two color-versions, but different ones (black, silver).

In this particular case, the Olympus XZ-1 and the Panasonic TZ100 have exactly the same width and height, and, thus, have identically-sized bodies. However, the Panasonic is markedly heavier (13 percent) than the Olympus. In this context, it is worth noting that neither the XZ-1 nor the TZ100 are weather-sealed.

The power pack in the TZ100 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. 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 XZ-1 was launched at a markedly lower price (by 29 percent) than the TZ100, 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus XZ-1 features a 1/1.7-inch sensor and the Panasonic TZ100 an one-inch sensor. The sensor area in the TZ100 is 152 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.4 and 2.7. The sensor in the XZ-1 has a native 4:3 aspect ratio, while the one in the TZ100 offers a 3:2 aspect.

With 20MP, the TZ100 offers a higher resolution than the XZ-1 (10.1MP), but the TZ100 nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 2.13μm for the XZ-1) due to its larger sensor. Moreover, the TZ100 is a much more recent model (by 5 years) than the XZ-1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

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 XZ-1 are 18.3 x 13.8 inches or 46.5 x 35 cm for good quality, 14.7 x 11 inches or 37.2 x 28 cm for very good quality, and 12.2 x 9.2 inches or 31 x 23.3 cm for excellent quality prints.

The Olympus XZ-1 has a native sensitivity range from ISO 100 to ISO 6400. 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.

In terms of underlying technology, the XZ-1 is build around a CCD sensor, while the TZ100 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 XZ-1 (overall score 36 points higher). The advantage is based on 4 bits higher color depth, 2.1 EV in additional dynamic range, and 2.3 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.

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, but the TZ100 provides a better video resolution than the XZ-1. 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 TZ100 has an electronic viewfinder (1166k dots), which can be very helpful when shooting in bright sunlight. In contrast, the XZ-1 relies on live view and the rear LCD for framing. That said, the XZ-1 can be equipped with an optional viewfinder – the VF-2. The adjacent table lists some of the other core features of the Olympus XZ-1 and Panasonic TZ100 along with similar information for a selection of comparators.

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 XZ-1 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 Olympus XZ-1 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.

Both the XZ-1 and the TZ100 have zoom lenses built in. The XZ-1 has a 28-112mm f/1.8-2.5 optic and the TZ100 offers a 25-250mm f/2.8-5.9 (focal lengths in full frame equivalent terms). Hence, the Panasonic provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Olympus. The XZ-1 offers the faster maximum aperture.

Concerning the storage of imaging data, both the XZ-1 and the TZ100 write their files to SDXC cards. The TZ100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the XZ-1 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 XZ-1 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 XZ-1 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 XZ-1 and the TZ100 have been discontinued, but can regularly be found used on ebay. The XZ-1 was replaced by the Olympus XZ-2, while the TZ100 was followed by the Panasonic TZ200. Further information on the features and operation of the XZ-1 and TZ100 can be found, respectively, in the Olympus XZ-1 Manual (free pdf) or the online Panasonic TZ100 Manual.

Review summary

So how do things add up? Which of the two cameras – the Olympus XZ-1 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.

Arguments in favor of the Olympus XZ-1:

• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
• Less heavy: Is lighter (by 37g or 12 percent) and hence easier to carry around.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in January 2011).

Advantages of the Panasonic Lumix DMC-TZ100:

• More detail: Has more megapixels (20 vs 10.1MP), which boosts linear resolution by 44%.
• Better image quality: Scores substantially higher (36 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (4 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (2.1 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.3 stops ISO advantage).
• Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 614k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (10 vs 2 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• 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 of technical progress since the XZ-1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the TZ100 is the clear winner of the contest (17 : 5 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 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 XZ-1 and the Panasonic TZ100 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 XZ-1 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 why expert reviews 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, please note that some of the review sites have changed their methodology and reporting over time.
