Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D300 and the Nikon D90? 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 Nikon D300 and the Nikon D90 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

Size Nikon D300 vs Nikon D90
Compare D300 versus D90 top
Comparison D300 or D90 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D90 is notably smaller (19 percent) than the Nikon D300. Moreover, the D90 is markedly lighter (24 percent) than the D300. It is worth mentioning in this context that the D300 is splash and dust resistant, while the D90 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Nikon Lens Catalog.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 D90 was launched at a markedly lower price (by 28 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.

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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D300 and Nikon D90 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 12.2 megapixels. This similarity in sensor specs implies that both the D300 and the D90 have the same pixel density, as well as the same pixel size. It should, however, be noted that the D90 is a somewhat more recent model (by 1 year) than the D300, and its sensor might have benefitted from technological advances during this time.

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 Nikon D90 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 200-6400.

D300 versus D90 MP

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 consideration, the D90 has a markedly higher DXO score than the D300 (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.5 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D300 and the D90 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the D300 offers a wider field of view (100%) than the one in the D90 (96%), so that a larger proportion of the captured image is visible in the finder. The table below summarizes some of the other core capabilities of the Nikon D300 and Nikon D90 in connection with corresponding information for a sample of similar cameras.

Studio photographers will appreciate that the Nikon D300 (unlike the D90) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D300 and the D90 have been discontinued, but can regularly be found used on eBay. The D300 was replaced by the Nikon D300S, while the D90 was followed by the Nikon D7000. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.

Review summary

So what conclusions can be drawn? Is the Nikon D300 better than the Nikon D90 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Nikon D300:

  • More complete view: Has a viewfinder with a larger field of view (100% vs 96%).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (6 vs 4.5 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 850) 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 on the market for longer (launched in August 2007).


Reasons to prefer the Nikon D90:

  • Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 720/24p video.
  • More compact: Is smaller (132x103mm vs 147x114mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 222g or 24 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (28 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the D300 comes out slightly ahead of the D90 (8 : 7 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 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 Nikon D300 and the Nikon D90 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 incomplete and does no justice, for example, to the way the D300 or the D90 perform in practice. 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.

Expert reviews

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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 assessments were made in relation to similar cameras of the same technological generation. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
