OM System OM-5 vs Panasonic FZ300
The OM System OM-5 and the Panasonic Lumix DMC-FZ300 (labelled Panasonic FZ330 in some countries) are two digital cameras that were announced, respectively, in October 2022 and July 2015. The OM-5 is a mirrorless interchangeable lens camera, while the FZ300 is a fixed lens compact. The cameras are based on a Four Thirds (OM-5) and a 1/2.3-inch (FZ300) sensor. The OM System has a resolution of 20.2 megapixels, whereas the Panasonic 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 OM System OM-5 and the Panasonic Lumix DMC-FZ300? 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 OM System OM-5 and the Panasonic FZ300 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 width, height and depth dimensions are rounded to the nearest millimeter.
The OM-5 can be obtained in two different colors (black, silver), while the FZ300 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 Panasonic FZ300 is notably larger (14 percent) than the OM System OM-5. 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.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the FZ300 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 OM-5 gets 310 shots out of its OM System BLS-50 battery, while the FZ300 can take 380 images on a single charge of its Panasonic DMW-BLC12 power pack. The power pack in the OM-5 can be charged via the USB port, so that it is not always necessary to take the battery charger along 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 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 FZ300 was launched at a lower price than the OM-5, 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 size of the sensor inside a digital camera is one of the key determinants 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 OM System OM-5 features a Four Thirds sensor and the Panasonic FZ300 a 1/2.3-inch sensor. The sensor area in the FZ300 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. 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 FZ300 (12MP), but the OM-5 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 1.53μm for the FZ300) due to its larger sensor. Moreover, the OM-5 is a much more recent model (by 7 years and 3 months) than the FZ300, 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 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 Panasonic FZ300 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 OM-5 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the FZ300, 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 OM System OM-5 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 64-25600. The corresponding ISO settings for the Panasonic Lumix DMC-FZ300 are ISO 100 to ISO 6400 (no boost).
In terms of underlying technology, the OM-5 is build around a CMOS sensor, while the FZ300 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.

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score.

One difference between the cameras concerns the presence of an on-board flash. The FZ300 has one, while the OM-5 does not. While the built-in flash of the FZ300 is not very powerful, it can at times be useful as a fill-in light.
Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.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, both cameras under consideration feature an 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 OM System OM-5 and the Panasonic FZ300 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 OM-5 and the FZ300 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 FZ300 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 OM System OM-5 and Panasonic Lumix DMC-FZ300 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Further information on the features and operation of the OM-5 and FZ300 can be found, respectively, in the OM System OM-5 Manual (free pdf) or the online Panasonic FZ300 Manual.
Review summary
So what conclusions can be drawn? Which of the two cameras – the OM System OM-5 or the Panasonic FZ300 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the OM System OM-5:
- More detail: Offers more megapixels (20.2 vs 12MP) with a 30% higher linear resolution.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better image quality: Features a larger and more technologically advanced imaging sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More compact: Is smaller (125x85mm vs 132x92mm) and thus needs less room in the bag.
- Easier travel charging: Can be conveniently charged via its USB port.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Reflects 7 years and 3 months of technical progress since the FZ300 launch.

Reasons to prefer the Panasonic Lumix DMC-FZ300:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.68x).
- Faster burst: Shoots at higher frequency (12 vs 10 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has an integrated lens, whereas the OM-5 necessitates an extra lens.
- Longer lasting: Gets more shots (380 versus 310) out of a single battery charge.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been around for much longer (launched in July 2015).
If the number of relative strengths (bullet points above) is taken as a guide, the OM-5 is the clear winner of the match-up (15 : 7 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 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 OM System OM-5 and the Panasonic FZ300 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom 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 says little about, for example, the shooting experience and imaging performance of the OM-5 and the FZ300 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 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 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
