Panasonic GH1 vs TS7

The Panasonic Lumix DMC-GH1 and the Panasonic Lumix DC-TS7 (labelled Panasonic FT7 in some countries) are two digital cameras that were officially introduced, respectively, in March 2009 and May 2018. The GH1 is a mirrorless interchangeable lens camera, while the TS7 is a fixed lens compact. The cameras are based on a Four Thirds (GH1) and a 1/2.3-inch (TS7) sensor. The GH1 has a resolution of 12 megapixels, whereas the TS7 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-GH1 and the Panasonic Lumix DC-TS7? 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 GH1 and the Panasonic TS7. 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 measures are rounded to the nearest millimeter.

The GH1 can be obtained in two different colors (black, red), while the TS7 is available in three color-versions (black, blue, orange).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic TS7 is notably smaller (20 percent) than the Panasonic GH1. It is noteworthy in this context that the TS7 is splash and dust-proof, while the GH1 does not feature any corresponding weather-sealing. More than that, the TS7 is water-proof up to 31m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TS7 has a lens built in, whereas the GH1 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 GH1 and their specifications in the Micro Four Thirds Lens Catalog.

The power pack in the TS7 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The TS7 was launched at a lower price than the GH1, 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. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 GH1 features a Four Thirds sensor and the Panasonic TS7 a 1/2.3-inch sensor. The sensor area in the TS7 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.

Despite having a smaller sensor, the TS7 offers a higher resolution of 20.2 megapixels, compared with 12 MP of the GH1. 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 4.33μm for the GH1). However, it should be noted that the TS7 is much more recent (by 9 years and 2 months) than the GH1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Panasonic TS7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TS7 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 GH1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Panasonic Lumix DMC-GH1 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Panasonic Lumix DC-TS7 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.

In terms of underlying technology, the GH1 is build around a CMOS sensor, while the TS7 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.

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"). 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 have a sensor with sufficiently fast read-out times for moving pictures, but the TS7 provides a better video resolution than the GH1. It can shoot movie footage at 4K/30p, while the GH1 is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the GH1 offers a higher resolution than the one in the TS7 (1440k vs 1170k dots).

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

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 TS7 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 GH1 writes its imaging data to SDHC cards, while the TS7 uses SDXC cards. The TS7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GH1 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 Panasonic Lumix DMC-GH1 and Panasonic Lumix DC-TS7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH1 has a hotshoe, while the TS7 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the GH1 and the TS7 have been discontinued, but can regularly be found used on ebay. The GH1 was replaced by the Panasonic GH2, while the TS7 does not have a direct successor. Further information on the features and operation of the GH1 and TS7 can be found, respectively, in the Panasonic GH1 Manual (free pdf) or the online Panasonic TS7 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Panasonic GH1 and the Panasonic TS7? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Panasonic Lumix DMC-GH1:

• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (1440k vs 1170k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.45x).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/1300s) 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.
• More heavily discounted: Has been available for much longer (launched in March 2009).

Reasons to prefer the Panasonic Lumix DC-TS7:

• More detail: Has more megapixels (20.2 vs 12MP), which boosts linear resolution by 30%.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/24p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
• Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Ready to shoot: Has an integrated lens, whereas the GH1 necessitates an extra lens.
• More compact: Is smaller (117x76mm vs 124x90mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the GH1).
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 31m).
• 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 affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 9 years and 2 months of technical progress since the GH1 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the TS7 emerges as the winner of the match-up (16 : 13 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 Panasonic GH1 and the Panasonic TS7 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom 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 says little about, for example, the shooting experience and imaging performance of the GH1 and the TS7 in practical situations. 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 hands-on reviews by experts 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.

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

The above review scores should be interpreted 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. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
