Canon 1D vs Olympus TG-5

The Canon EOS-1D and the Olympus Tough TG-5 are two digital cameras that were revealed to the public, respectively, in September 2001 and May 2017. The 1D is a DSLR, while the TG-5 is a fixed lens compact. The cameras are based on an APS-H (1D) and a 1/2.3-inch (TG-5) sensor. The Canon has a resolution of 4.1 megapixels, whereas the Olympus provides 12 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 Canon EOS-1D and the Olympus Tough TG-5? 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 Canon 1D and the Olympus TG-5 are illustrated 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 TG-5 can be obtained in two different colors (black, red), while the 1D 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 Olympus TG-5 is considerably smaller (70 percent) than the Canon 1D. 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-5 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-5 has a lens built in, whereas the 1D 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 1D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 1D gets 500 shots out of its Canon NP-E3 battery, while the TG-5 can take 340 images on a single charge of its Olympus LI-92B power pack. As can be seen in the images above, the 1D has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the TG-5 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. 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-5 was launched at a lower price than the 1D, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D features an APS-H sensor and the Olympus TG-5 a 1/2.3-inch sensor. The sensor area in the TG-5 is 95 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 5.6. The sensor in the 1D has a native 3:2 aspect ratio, while the one in the TG-5 offers a 4:3 aspect.

Despite having a smaller sensor, the TG-5 offers a higher resolution of 12 megapixels, compared with 4.1 MP of the 1D. 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 1.53μm versus 11.56μm for the 1D). However, it should be noted that the TG-5 is much more recent (by 15 years and 7 months) than the 1D, 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-5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TG-5 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 cm. The corresponding values for the Canon 1D are 12.5 x 8.3 inches or 31.7 x 21.1 cm for good quality, 10 x 6.6 inches or 25.4 x 16.9 cm for very good quality, and 8.3 x 5.5 inches or 21.1 x 14.1 cm for excellent quality prints.

The Canon EOS-1D has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Olympus Tough TG-5 are ISO 100 to ISO 12800 (no boost).

In terms of underlying technology, the 1D is build around a CCD sensor, while the TG-5 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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.

Many modern cameras cannot only take still pictures, but also record videos. The TG-5 indeed provides for movie recording, while the 1D does not. The highest resolution format that the TG-5 can use is 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 1D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the TG-5 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 1D and Olympus TG-5 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 1D, but is missing on the TG-5 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 Olympus TG-5 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 1D writes its imaging data to Compact Flash cards, while the TG-5 uses SDXC 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 Canon EOS-1D and Olympus Tough TG-5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 1D has a hotshoe, while the TG-5 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Canon 1D (unlike the TG-5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the TG-5 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 1D and the TG-5 have been discontinued, but can regularly be found used on ebay. The 1D was replaced by the Canon 1D Mark II, while the TG-5 was followed by the Olympus TG-6. Further information on the features and operation of the 1D and TG-5 can be found, respectively, in the Canon 1D Manual (free pdf) or the online Olympus TG-5 Manual.

Review summary

So how do things add up? Is the Canon 1D better than the Olympus TG-5 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon EOS-1D:

• 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.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/16000s vs 1/2000s) to freeze action.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (500 versus 340) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been available for much longer (launched in September 2001).

Advantages of the Olympus Tough TG-5:

• More detail: Has more megapixels (12 vs 4.1MP), which boosts linear resolution by 67%.
• Broader imaging potential: Can capture not only stills but also 4K/30p video.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (460k vs 120k dots).
• Faster burst: Shoots at higher frequency (20 vs 8 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 1D requires a separate lens.
• More compact: Is smaller (113x66mm vs 156x158mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the 1D).
• 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 fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• 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 15 years and 7 months of technical progress since the 1D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the TG-5 is the clear winner of the contest (17 : 13 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Canon 1D and the Olympus TG-5 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 1D or the TG-5 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 why expert reviews 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.

The above review scores should be interpreted with care, 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 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.
