Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DC-LX100 II 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

The physical size and weight of the Panasonic LX100 II and the Panasonic TZ90 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 TZ90 can be obtained in two different colors (black, silver), while the LX100 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 TZ90 is somewhat smaller (1 percent) than the Panasonic LX100 II. Moreover, the TZ90 is markedly lighter (18 percent) than the LX100 II. In this context, it is worth noting that neither the LX100 II nor the TZ90 are weather-sealed.

The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Convert to Imperial

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 TZ90 was launched at a markedly lower price (by 55 percent) than the LX100 II, which puts it into a different market segment. 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 Panasonic LX100 II features a Four Thirds sensor and the Panasonic TZ90 a 1/2.3-inch sensor. The sensor area in the TZ90 is 85 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.2 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. The LX100 II has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

Despite having a smaller sensor, the TZ90 offers a higher resolution of 20.2 megapixels, compared with 16.8 MP of the LX100 II. 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 3.32μm for the LX100 II). Moreover, it should be noted that the LX100 II is a somewhat more recent model (by 1 year and 4 months) than the TZ90, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the 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 Panasonic LX100 II are 23.7 x 17.8 inches or 60.1 x 45.1 cm for good quality, 18.9 x 14.2 inches or 48.1 x 36.1 cm for very good quality, and 15.8 x 11.8 inches or 40.1 x 30.1 cm for excellent quality prints.

The Panasonic Lumix DC-LX100 II has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. 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 LX100 II 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.

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.

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

One difference between the cameras concerns the presence of an on-board flash. The TZ90 has one, while the LX100 II does not. While the built-in flash of the TZ90 is not very powerful, it can at times be useful as a fill-in light.

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 Panasonic LX100 II 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.

Both the LX100 II and the TZ90 have zoom lenses built in. The LX100 II has a 24-75mm f/1.7-2.8 optic and the TZ90 offers a 24-720mm f/3.3-6.4 (focal lengths in full frame equivalent terms). Hence, the LX100 II and TZ90 provide the same view at the wide-angle end, but the TZ90 has more tele-photo reach at the long end. The LX100 II offers the faster maximum aperture.

Concerning the storage of imaging data, both the LX100 II and the TZ90 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of 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 Panasonic Lumix DC-LX100 II 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 LX100 II 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 LX100 II and the TZ90 have been discontinued, but can regularly be found used on ebay. The TZ90 was replaced by the Panasonic TZ95, while the LX100 II does not have a direct successor. Further information on the features and operation of the LX100 II and TZ90 can be found, respectively, in the Panasonic LX100 II Manual (free pdf) or the online Panasonic TZ90 Manual.

Review summary

So how do things add up? Is the Panasonic LX100 II better than the Panasonic TZ90 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Panasonic Lumix DC-LX100 II:

• 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.
• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2764k vs 1166k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.46x).
• More detailed LCD: Has a higher resolution rear screen (1240k vs 1040k dots).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.7 vs f/3.3).
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Is somewhat more recent (announced 1 year and 4 months after the TZ90).

Advantages of the Panasonic Lumix DC-TZ90:

• More detail: Has more megapixels (20.2 vs 16.8MP), which boosts linear resolution by 9%.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Less heavy: Has a lower weight (by 70g or 18 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (380 versus 300) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (55 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in April 2017).

If the count of individual advantages (bullet points above) is taken as a guide, the LX100 II is the clear winner of the match-up (14 : 9 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 Panasonic LX100 II and the Panasonic TZ90 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 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 LX100 II or the TZ90 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.
