Panasonic GF1 vs TS7

The Panasonic Lumix DMC-GF1 and the Panasonic Lumix DC-TS7 (labelled Panasonic FT7 in some countries) are two digital cameras that were officially introduced, respectively, in September 2009 and May 2018. The GF1 is a mirrorless interchangeable lens camera, while the TS7 is a fixed lens compact. The cameras are based on a Four Thirds (GF1) and a 1/2.3-inch (TS7) sensor. The GF1 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-GF1 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 physical size and weight of the Panasonic GF1 and the Panasonic TS7 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 width, height and depth measures are rounded to the nearest millimeter.

The TS7 can be obtained in three different colors (black, blue, orange), while the GF1 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 TS7 is notably larger (5 percent) than the Panasonic GF1. It is noteworthy in this context that the TS7 is splash and dust-proof, while the GF1 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 GF1 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 GF1 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GF1 gets 380 shots out of its Panasonic DMW-BLB13 battery, while the TS7 can take 300 images on a single charge of its Panasonic DMW-BCM13 power pack. 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.

The price is, of course, an important factor in any camera decision. 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 GF1, 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 size of the imaging sensor is a crucial determinant 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. 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 GF1 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 GF1. 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 GF1). However, it should be noted that the TS7 is much more recent (by 8 years and 8 months) than the GF1, 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 GF1 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-GF1 has a native sensitivity range from ISO 100 to ISO 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 GF1 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the TS7 provides a better video resolution than the GF1. It can shoot movie footage at 4K/30p, while the GF1 is limited to 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the TS7 has an electronic viewfinder (1170k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GF1 relies on live view and the rear LCD for framing. That said, the GF1 can be equipped with an optional viewfinder – the DMW-LVF1. The table below summarizes some of the other core capabilities of the Panasonic GF1 and Panasonic TS7 in connection with corresponding information for a sample of similar cameras.

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 GF1 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 GF1 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-GF1 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 GF1 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 GF1 and the TS7 have been discontinued, but can regularly be found used on ebay. The GF1 was replaced by the Panasonic DMC-GF2, while the TS7 does not have a direct successor. Further information on the features and operation of the GF1 and TS7 can be found, respectively, in the Panasonic GF1 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 GF1 and the Panasonic TS7? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Panasonic Lumix DMC-GF1:

• 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.
• 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.
• Longer lasting: Can take more shots (380 versus 300) on a single battery charge.
• 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 September 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 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 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 GF1 necessitates an extra lens.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the GF1).
• 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 8 years and 8 months of technical progress since the GF1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the TS7 is the clear winner of the contest (16 : 9 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 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 GF1 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the GF1 and the TS7 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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 review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
