Leica CL vs Panasonic TZ100

The Leica CL (Typ 7323) and the Panasonic Lumix DMC-TZ100 (labelled Panasonic ZS100 in some countries) are two digital cameras that were revealed to the public, respectively, in November 2017 and January 2016. The CL is a mirrorless interchangeable lens camera, while the TZ100 is a fixed lens compact. The cameras are based on an APS-C (CL) and an one-inch (TZ100) sensor. The Leica has a resolution of 24.1 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 Leica CL (Typ 7323) 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 Leica CL and the Panasonic TZ100 are illustrated 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.

The TZ100 can be obtained in two different colors (black, silver), while the CL 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 notably smaller (29 percent) than the Leica CL. In this context, it is worth noting that neither the CL 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 CL is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the CL gets 220 shots out of its BP-DC12 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. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The TZ100 was launched at a lower price than the CL, 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.

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 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Leica CL features an APS-C sensor and the Panasonic TZ100 an one-inch sensor. The sensor area in the TZ100 is 69 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 24.1MP, the CL offers a higher resolution than the TZ100 (20MP), but the CL nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 2.41μm for the TZ100) due to its larger sensor. Moreover, the CL is a somewhat more recent model (by 1 year and 10 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 CL has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica CL implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the CL for good quality output (200 dots per inch) amounts to 30.1 x 20.1 inches or 76.4 x 51 cm, for very good quality (250 dpi) 24.1 x 16.1 inches or 61.1 x 40.8 cm, and for excellent quality (300 dpi) 20 x 13.4 inches or 50.9 x 34 cm. The corresponding values for the Panasonic TZ100 are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The Leica CL (Typ 7323) has a native sensitivity range from ISO 100 to ISO 50000. 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).

Feature comparison

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 CL offers a substantially higher resolution than the one in the TZ100 (2360k vs 1166k dots).

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

One feature that is present on the CL, but is missing on the TZ100 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 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 Leica CL 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 CL and the TZ100 write their files to SDXC cards. The CL supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the TZ100 can use UHS-I cards (up to 104 MB/s).

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 Leica CL (Typ 7323) 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 CL has a hotshoe, while the TZ100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The CL is a recent model that features in the current product line-up of Leica. 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 features and operation of the CL and TZ100 can be found, respectively, in the Leica CL Manual (free pdf) or the online Panasonic TZ100 Manual.

Review summary

So how do things add up? Is the Leica CL better than the Panasonic TZ100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Leica CL (Typ 7323):

• More detail: Offers more megapixels (24.1 vs 20MP) with a 10% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1166k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.49x vs 0.46x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
• 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.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More modern: Is somewhat more recent (announced 1 year and 10 months after the TZ100).

Advantages 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 CL necessitates an extra lens.
• More compact: Is smaller (111x65mm vs 131x78mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the CL).
• Longer lasting: Gets more shots (300 versus 220) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• 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 CL is the clear winner of the match-up (15 : 10 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Leica CL 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 remains incomplete and does no justice, for example, to the way the CL or the TZ100 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 above review scores should be interpreted 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.
