Nikon D40X vs Olympus TG-4
The Nikon D40X and the Olympus Tough TG-4 are two digital cameras that were announced, respectively, in March 2007 and April 2015. The D40X is a DSLR, while the TG-4 is a fixed lens compact. The cameras are based on an APS-C (D40X) and a 1/2.3-inch (TG-4) sensor. The Nikon has a resolution of 10 megapixels, whereas the Olympus provides 15.9 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 Nikon D40X and the Olympus Tough TG-4? 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.
An illustration of the physical size and weight of the Nikon D40X and the Olympus TG-4 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the TG-4 is also available in two color-versions, but different ones (black, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus TG-4 is considerably smaller (37 percent) than the Nikon D40X. It is noteworthy in this context that the TG-4 is splash and dust-proof, while the D40X does not feature any corresponding weather-sealing. More than that, the TG-4 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-4 has a lens built in, whereas the D40X 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 D40X and their specifications in the Nikon Lens Catalog.
Concerning battery life, the D40X gets 520 shots out of its EN-EL9 battery, while the TG-4 can take 380 images on a single charge of its LI-92B power pack. The power pack in the TG-4 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.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The TG-4 was launched at a lower price than the D40X, 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.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D40X features an APS-C sensor and the Olympus TG-4 a 1/2.3-inch sensor. The sensor area in the TG-4 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 D40X has a native 3:2 aspect ratio, while the one in the TG-4 offers a 4:3 aspect.
Despite having a smaller sensor, the TG-4 offers a higher resolution of 15.9 megapixels, compared with 10 MP of the D40X. 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 1.33μm versus 6.11μm for the D40X). However, it should be noted that the TG-4 is much more recent (by 8 years and 1 month) than the D40X, 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 Olympus TG-4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TG-4 for good quality output (200 dots per inch) amounts to 23 x 17.3 inch or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inch or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inch or 39 x 29.3 cm. The corresponding values for the Nikon D40X are 19.4 x 13 inch or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inch or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inch or 32.8 x 21.9 cm for excellent quality prints.
The Nikon D40X 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 Olympus Tough TG-4 are ISO 100 to ISO 6400 (no boost).
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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The TG-4 indeed provides for movie recording, while the D40X does not. The highest resolution format that the TG-4 can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the D40X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the TG-4 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Nikon D40X and Olympus TG-4 in connection with corresponding information for a sample of similar cameras.

The Olympus TG-4 has 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.
The D40X writes its imaging data to SDHC cards, while the TG-4 uses SDXC cards. The TG-4 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D40X cannot take advantage of Ultra High Speed SD cards.
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 D40X and Olympus Tough TG-4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D40X has a hotshoe, while the TG-4 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-4 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the D40X and the TG-4 have been discontinued, but can regularly be found used on eBay. The D40X was replaced by the Nikon D60 , while the TG-4 was followed by the Olympus TG-5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Olympus websites.
So what conclusions can be drawn? Which of the two cameras – the Nikon D40X or the Olympus TG-4 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Nikon D40X:
- 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.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (520 versus 380) 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 March 2007).
Arguments in favor of the Olympus Tough TG-4:
- More detail: Has more megapixels (15.9 vs 10MP), which boosts linear resolution by 24%.
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
- Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Comes with an integrated lens, while the D40X requires a separate lens.
- More compact: Is smaller (112x66mm vs 124x94mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the D40X).
- 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 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.
- 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 1 month of technical progress since the D40X launch.
If the count of individual advantages (bullet points above) is taken as a guide, the TG-4 is the clear winner of the contest (17 : 10 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 Nikon D40X and the Olympus TG-4 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 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 D40X and the TG-4 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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.
