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

An illustration of the physical size and weight of the Nikon P1100 and the OM System OM-5 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 OM-5 can be obtained in two different colors (black, silver), 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 OM-5 is considerably smaller (39 percent) than the Nikon P1100. It is noteworthy in this context that the OM-5 is splash and dust-proof, while the P1100 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the P1100 has a lens built in, whereas the OM-5 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 OM-5 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the P1100 gets 250 shots out of its Nikon EN-EL20a battery, while the OM-5 can take 310 images on a single charge of its OM System BLS-50 power pack. The battery packs of both cameras can be charged via USB, 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. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The P1100 was launched at a lower price than the OM-5, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 P1100 features a 1/2.3-inch sensor and the OM System OM-5 a Four Thirds sensor. The sensor area in the OM-5 is 704 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

With 20.2MP, the OM-5 offers a higher resolution than the P1100 (15.9MP), but the OM-5 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 1.33μm for the P1100) due to its larger sensor. However, the P1100 is a much more recent model (by 2 years and 3 months) than the OM-5, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the OM System OM-5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the OM-5 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Nikon P1100 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The OM-5 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the P1100, the OM-5 has the capacity to capture high quality composite images (80MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Nikon Coolpix P1100 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the OM System OM-5 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 64-25600.

In terms of underlying technology, the P1100 is build around a BSI-CMOS sensor, while the OM-5 uses a 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 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the OM-5 offers a slightly higher resolution than the one in the P1100 (2360k vs 2359k dots). The adjacent table lists some of the other core features of the Nikon P1100 and OM System OM-5 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The P1100 has one, while the OM-5 does not. While the built-in flash of the P1100 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the OM-5 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Nikon P1100 and the OM System OM-5 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 P1100 and the OM-5 write their files to SDXC cards. The OM-5 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the P1100 can use UHS-I cards (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 OM-5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the P1100 and the OM-5 are recent models that are part of the current product line-up. The OM-5 replaced the earlier Olympus E-M5 III, 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 there a clear favorite between the Nikon P1100 and the OM System OM-5? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Nikon Coolpix P1100:

• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• Ready to shoot: Has a lens built-in, whereas the OM-5 requires a separate lens.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 2 years and 3 months of technical progress since the OM-5 launch.

Arguments in favor of the OM System OM-5:

• High quality composites: Can combine several shots after pixel-shifting its sensor.
• 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.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (10 vs 7 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (125x85mm vs 146x119mm) and will fit more readily into a bag.
• Longer lasting: Gets more shots (310 versus 250) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More heavily discounted: Has been around for much longer (launched in October 2022).

If the count of individual advantages (bullet points above) is taken as a guide, the OM-5 is the clear winner of the contest (18 : 5 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 P1100 and the OM System OM-5 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the P1100 or the OM-5. 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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
