Body comparison

The physical size and weight of the Nikon D7100 and the Olympus TG-6 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The TG-6 can be obtained in two different colors (black, red), while the D7100 is only available in black.

Size Nikon D7100 vs Olympus TG-6
Compare D7100 versus TG-6 top
Comparison D7100 or TG-6 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus TG-6 is considerably smaller (49 percent) than the Nikon D7100. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments. More than that, the TG-6 is water-proof up to 15m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TG-6 has a lens built in, whereas the D7100 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 D7100 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the D7100 gets 950 shots out of its EN-EL15 battery, while the TG-6 can take 340 images on a single charge of its LI-92B power pack. The power pack in the TG-6 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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-6 was launched at a lower price than the D7100, 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.

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.

Of the two cameras under consideration, the Nikon D7100 features an APS-C sensor and the Olympus TG-6 a 1/2.3-inch sensor. The sensor area in the TG-6 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 5.6. The sensor in the D7100 has a native 3:2 aspect ratio, while the one in the TG-6 offers a 4:3 aspect.

Nikon D7100 and Olympus TG-6 sensor measures

With 24MP, the D7100 offers a higher resolution than the TG-6 (12MP), but the D7100 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 1.53μm for the TG-6) due to its larger sensor. However, the TG-6 is a much more recent model (by 6 years and 2 months) than the D7100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the D7100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon D7100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7100 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus TG-6 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 D7100 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. The corresponding ISO settings for the Olympus Tough TG-6 are ISO 100 to ISO 12800 (no boost).

In terms of underlying technology, the D7100 is build around a CMOS sensor, while the TG-6 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.

D7100 versus TG-6 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

One feature that is present on the D7100, but is missing on the TG-6 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The Nikon D7100 and the Olympus TG-6 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.

Concerning the storage of imaging data, both the D7100 and the TG-6 write their files to SDXC cards. The D7100 features dual card slots, which can be very useful in case a memory card fails. In contrast, the TG-6 only has one slot. 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 D7100 has a hotshoe, while the TG-6 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-6 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The TG-6 is a recent model that features in the current product line-up of Olympus. In contrast, the D7100 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the D7100 was succeeded by the Nikon D7200. Further information on the features and operation of the D7100 and TG-6 can be found, respectively, in the Nikon D7100 Manual (free pdf) or the online Olympus TG-6 Manual.

ilogo

Advantages of the Olympus Tough TG-6:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Faster burst: Shoots at higher frequency (20 vs 6 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the D7100 requires a separate lens.
  • More compact: Is smaller (113x66mm vs 136x107mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the D7100).
  • 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.
  • 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.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 6 years and 2 months of technical progress since the D7100 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D7100 is the clear winner of the match-up (18 : 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 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.

D7100 18:13 TG-6

How about other alternatives? Do the specifications of the Nikon D7100 and the Olympus TG-6 place the cameras among the top in their class? Find out in the latest Best DSLR 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 remains incomplete and does no justice, for example, to the way the D7100 or the TG-6 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 where reviews by experts come in. 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
