Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Coolpix P1100 and the OM System Tough TG-7? 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

An illustration of the physical size and weight of the Nikon P1100 and the OM System TG-7 is provided 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 TG-7 can be obtained in two different colors (black, red), while the P1100 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 OM System TG-7 is considerably smaller (57 percent) than the Nikon P1100. Moreover, the TG-7 is substantially lighter (82 percent) than the P1100. It is noteworthy in this context that the TG-7 is splash and dust-proof, while the P1100 does not feature any corresponding weather-sealing. More than that, the TG-7 is water-proof up to 15m and can, thus, be used for underwater photography.

Concerning battery life, the P1100 gets 250 shots out of its Nikon EN-EL20a battery, while the TG-7 can take 330 images on a single charge of its OM System LI-92B power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

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 TG-7 was launched at a markedly lower price (by 50 percent) than the P1100, which puts it into a different market segment. 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 imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

While the two cameras under review share the same sensor size, the P1100 offers a higher resolution of 15.9 megapixels, compared with 12 MP of the TG-7. This megapixels advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the P1100 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.33μm versus 1.53μm for the TG-7). In this context, it should be noted, however, that the P1100 is a somewhat more recent model (by 1 year and 4 months) than the TG-7, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the P1100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon P1100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the P1100 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the OM System TG-7 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 Nikon Coolpix P1100 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the OM System Tough TG-7 are ISO 100 to ISO 12800 (no boost).

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. 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 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the P1100 has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the TG-7 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Nikon P1100 and OM System TG-7 in connection with corresponding information for a sample of similar cameras.

The Nikon P1100 and the OM System TG-7 both have 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 P1100 and the TG-7 have zoom lenses built in. The P1100 has a 24-3000mm f/2.8-8.0 optic and the TG-7 offers a 25-100mm f/2.0-4.9 (focal lengths in full frame equivalent terms). Hence, the Nikon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the OM System. The TG-7 offers the faster maximum aperture.

Concerning the storage of imaging data, both the P1100 and the TG-7 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 Nikon Coolpix P1100 and OM System Tough TG-7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the P1100 has a hotshoe, while the TG-7 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Travel and landscape photographers will find it useful that the TG-7 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the P1100 and the TG-7 are recent models that are part of the current product line-up. The TG-7 replaced the earlier Olympus TG-6, while the P1100 followed on from the Nikon P1000. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and OM System websites.

Review summary

So what conclusions can be drawn? Is the Nikon P1100 better than the OM System TG-7 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Nikon Coolpix P1100:

• More detail: Offers more megapixels (15.9 vs 12MP) with a 15% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• 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 1/2000s) to freeze action.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• 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 TG-7).

Reasons to prefer the OM System Tough TG-7:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
• Faster burst: Shoots at higher frequency (20 vs 7 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.8).
• More compact: Is smaller (114x66mm vs 146x119mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 1161g or 82 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (330 versus 250) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 15m).
• Easier geotagging: Features an internal GPS sensor to log localization data.
• More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in September 2023).

If the count of individual advantages (bullet points above) is taken as a guide, the P1100 comes out slightly ahead of the TG-7 (13 : 12 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 Nikon P1100 and the OM System TG-7 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the P1100 and the TG-7 in practical situations. 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 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.

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. 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.
