Panasonic GH4 vs TZ90

The Panasonic Lumix DMC-GH4 and the Panasonic Lumix DC-TZ90 (labelled Panasonic ZS70 in some countries) are two digital cameras that were revealed to the public, respectively, in February 2014 and April 2017. The GH4 is a mirrorless interchangeable lens camera, while the TZ90 is a fixed lens compact. The cameras are based on a Four Thirds (GH4) and a 1/2.3-inch (TZ90) sensor. The GH4 has a resolution of 15.9 megapixels, whereas the TZ90 provides 20.2 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 Panasonic Lumix DMC-GH4 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 side-by-side display below illustrates the physical size and weight of the Panasonic GH4 and the Panasonic TZ90. 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 TZ90 can be obtained in two different colors (black, silver), while the GH4 is only available in black.

Compare GH4 versus TZ90 top
Comparison GH4 or TZ90 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic TZ90 is considerably smaller (39 percent) than the Panasonic GH4. It is worth mentioning in this context that the GH4 is splash and dust resistant, while the TZ90 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TZ90 has a lens built in, whereas the GH4 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 GH4 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GH4 gets 500 shots out of its DMW-BLF19 battery, while the TZ90 can take 380 images on a single charge of its DMW-BLG10 power pack. The power pack in the TZ90 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 TZ90 was launched at a lower price than the GH4, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GH4 features a Four Thirds sensor and the Panasonic TZ90 a 1/2.3-inch sensor. The sensor area in the TZ90 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Panasonic GH4 and Panasonic TZ90 sensor measures

Despite having a smaller sensor, the TZ90 offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the GH4. 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 3.76μm for the GH4). However, it should be noted that the TZ90 is much more recent (by 3 years and 2 months) than the GH4, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the TZ90 has no anti-alias filter installed, so that it can capture all the detail its 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 GH4 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The Panasonic Lumix DMC-GH4 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.

GH4 versus TZ90 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 GH4 provides substantially higher image quality than the TZ90, with an overall score that is 38 points higher. This advantage is based on 4.1 bits higher color depth, 2.2 EV in additional dynamic range, and 2.9 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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 GH4 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.

Concerning the storage of imaging data, both the GH4 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.

It is notable that the GH4 has a hotshoe, while the TZ90 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Panasonic GH4 (unlike the TZ90) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the GH4 and the TZ90 have been discontinued, but can regularly be found used on eBay. The GH4 was replaced by the Panasonic GH5, while the TZ90 was followed by the Panasonic TZ95. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic website.

Review summary

So what is the bottom line? Is there a clear favorite between the Panasonic GH4 and the Panasonic TZ90? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Panasonic Lumix DMC-GH4:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores substantially higher (38 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (4.1 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (2.2 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (2.9 stops ISO advantage).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 1166k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.67x vs 0.46x).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (12 vs 10 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Longer lasting: Can take more shots (500 versus 380) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been available for much longer (launched in February 2014).


Arguments in favor of the Panasonic Lumix DC-TZ90:

  • More detail: Has more megapixels (20.2 vs 15.9MP), which boosts linear resolution by 13%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Ready to shoot: Has an integrated lens, whereas the GH4 necessitates an extra lens.
  • More compact: Is smaller (112x67mm vs 133x93mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the GH4).
  • 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.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 3 years and 2 months of technical progress since the GH4 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the GH4 is the clear winner of the match-up (20 : 9 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.

GH4 20:09 TZ90

How about other alternatives? Do the specifications of the Panasonic GH4 and the Panasonic TZ90 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 GH4 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 hands-on reviews by experts are important. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
