Nikon D300 vs Panasonic G2
The Nikon D300 and the Panasonic Lumix DMC-G2 are two digital cameras that were announced, respectively, in August 2007 and March 2010. The D300 is a DSLR, while the G2 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D300) and a Four Thirds (G2) sensor. The Nikon has a resolution of 12.2 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 Nikon D300 and the Panasonic Lumix DMC-G2? 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.
The physical size and weight of the Nikon D300 and the Panasonic G2 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 width, height and depth measures are rounded to the nearest millimeter.
The G2 can be obtained in three different colors (black, blue, red), while the D300 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 G2 is considerably smaller (38 percent) than the Nikon D300. Moreover, the G2 is substantially lighter (54 percent) than the D300. It is worth mentioning in this context that the D300 is splash and dust resistant, while the G2 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D300) and the Micro Four Thirds Lens Catalog (G2). Mirrorless cameras, such as the G2, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

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 G2 was launched at a markedly lower price (by 67 percent) than the D300, which puts it into a different market segment. 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D300 features an APS-C sensor and the Panasonic G2 a Four Thirds sensor. The sensor area in the G2 is 40 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the D300 has a native 3:2 aspect ratio, while the one in the G2 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 12.2MP, the D300 offers a slightly higher resolution than the G2 (12MP), but the D300 nevertheless has larger individual pixels (pixel pitch of 5.53μm versus 4.33μm for the G2) due to its larger sensor. However, the G2 is a much more recent model (by 2 years and 6 months) than the D300, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The Nikon D300 has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 100-6400. The corresponding ISO settings for the Panasonic Lumix DMC-G2 are ISO 100 to ISO 6400 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under review, the D300 provides substantially higher image quality than the G2, with an overall score that is 14 points higher. This advantage is based on 0.9 bits higher color depth, 1.7 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The G2 indeed provides for movie recording, while the D300 does not. The highest resolution format that the G2 can use is 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G2 has an electronic viewfinder (1440k dots), while the D300 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the G2 has a higher magnification than the one of the D300 (0.70x vs 0.63x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Nikon D300, the Panasonic G2, and comparable cameras.

One feature that is present on the D300, but is missing on the G2 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 G2 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D300 does not have a selfie-screen.
The Nikon D300 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 D300 writes its imaging data to Compact Flash cards, while the G2 uses SDXC 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 D300 and Panasonic Lumix DMC-G2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D300 (unlike the G2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D300 and the G2 have been discontinued, but can regularly be found used on eBay. The D300 was replaced by the Nikon D300S, while the G2 was followed by the Panasonic G3. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Panasonic websites.
So what is the bottom line? Is the Nikon D300 better than the Panasonic G2 or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Nikon D300:
- Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.7 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- More detailed LCD: Has a higher resolution rear screen (922k vs 460k dots).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (6 vs 2.6 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Can take more shots (1000 versus 360) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- 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 August 2007).
Reasons to prefer the Panasonic Lumix DMC-G2:
- Broader imaging potential: Can capture not only stills but also 720/30p video.
- More framing info: Has an electronic viewfinder that displays shooting data.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.63x).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More compact: Is smaller (124x84mm vs 147x114mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 497g or 54 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (67 percent cheaper at launch).
- More modern: Reflects 2 years and 6 months of technical progress since the D300 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the D300 emerges as the winner of the contest (13 : 11 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 D300 and the Panasonic G2 place the cameras among the top in their class? Find out in the latest Best DSLR 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D300 or the G2. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
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 (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.
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. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
