The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The OM System TG-7 was launched in the US market at a price of $549. 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 with a 35mm slide

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

The OM System TG-7 features a 1/2.3-inch sensor and has a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the OM System TG-7 among the smaller-sensor digicams that favor affordability and compact design.

OM System TG-7 sensor measures

For most 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.

One convenient feature of the TG-7 is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.

It is notable that the TG-7 offers wifi support. Wifi can be a very convenient means to transfer image data to an off-camera location.

The TG-7 has a zoom lens built in (4.5-18mm f/2.0-4.9), which, in full frame equivalent terms, provides a focal length range from 25 to 100mm. The camera is, hence, ready to shoot, while remaining more compact in size than an interchangeable lens camera with an optic that offers similar focal length and aperture specifications.

Further information on the features and operation of the TG-7 can be found in the free online OM System TG-7 Manual or on the OM System support site.

Expert reviews

While the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the TG-7 handle or 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. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

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

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.

Is it difficult to use manual focus lenses with the OM System TG-7?

The TG-7 offers focus peaking as a manual focus aid. This feature works by placing a colored highlight on in-focus zones within the image.

Does the OM System TG-7 feature an autofocus assist light?

Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.

Does the OM System TG-7 support the Ultra High Speed (UHS) bus interface for SD cards?

Yes, the camera can indeed use UHS-I cards (data transfer speed of up to 104 MB/s).

Which battery does the OM System TG-7 use?

The camera gets its power from the OM System LI-92B (here at amazon), which is a rechargeable Lithium-Ion power pack.

Does the OM System TG-7 support geotagging?

The TG-7 has a built-in GPS (Global Positioning System) module and can embed location information in the EXIF data of the captured image.

Where can I find the best deals for the OM System TG-7?

Grey imports from Asia, as found on ebay, are often very attractively priced. However, these cameras come without a warranty from OM System.
