Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M8 and the Nikon D300S? 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 side-by-side display below illustrates the physical size and weight of the Leica M8 and the Nikon D300S. 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 M8 can be obtained in two different colors (black, silver), while the D300S 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 Nikon D300S is considerably larger (52 percent) than the Leica M8. Moreover, the D300S is substantially heavier (59 percent) than the M8. It is noteworthy in this context that the D300S is splash and dust-proof, while the M8 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 Leica M Lens Catalog (M8) and the Nikon Lens Catalog (D300S).

Concerning battery life, the M8 gets 550 shots out of its Leica BLI-312 battery, while the D300S can take 950 images on a single charge of its Nikon EN-EL3e power pack.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The D300S was launched at a markedly lower price (by 67 percent) than the M8, 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 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 Leica M8 features an APS-H sensor and the Nikon D300S an APS-C sensor. The sensor area in the D300S is 23 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the D300S offers a higher resolution of 12.2 megapixels, compared with 10.4 MP of the M8. 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 5.53μm versus 6.84μm for the M8). However, it should be noted that the D300S is much more recent (by 2 years and 10 months) than the M8, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the M8 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon D300S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D300S for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inches or 54.5 x 36.2 cm, for very good quality (250 dpi) 17.2 x 11.4 inches or 43.6 x 28.9 cm, and for excellent quality (300 dpi) 14.3 x 9.5 inches or 36.3 x 24.1 cm. The corresponding values for the Leica M8 are 19.7 x 13.2 inches or 50 x 33.4 cm for good quality, 15.7 x 10.5 inches or 40 x 26.7 cm for very good quality, and 13.1 x 8.8 inches or 33.3 x 22.3 cm for excellent quality prints.

The Leica M8 has a native sensitivity range from ISO 160 to ISO 2500. The corresponding ISO settings for the Nikon D300S are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

In terms of underlying technology, the M8 is build around a CCD sensor, while the D300S 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.

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. Of the two cameras under consideration, the D300S offers substantially better image quality than the M8 (overall score 11 points higher). The advantage is based on 1.4 bits higher color depth, 0.9 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D300S indeed provides for movie recording, while the M8 does not. The highest resolution format that the D300S can use is 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The M8 and the D300S 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 following table reports on some other key feature differences and similarities of the Leica M8, the Nikon D300S, and comparable cameras.

One feature that is present on the D300S, but is missing on the M8 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 Nikon D300S 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 M8 writes its imaging data to SDXC cards, while the D300S uses Compact Flash or SDXC cards. The D300S features dual card slots, which can be very useful in case a memory card fails. In contrast, the M8 only has one slot.

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 Leica M8 and Nikon D300S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D300S (unlike the M8) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the M8 and the D300S have been discontinued, but can regularly be found used on ebay. The M8 was replaced by the Leica M9, while the D300S was followed by the Nikon D500. Further information on the features and operation of the M8 and D300S can be found, respectively, in the Leica M8 Manual (free pdf) or the online Nikon D300S Manual.

Review summary

So how do things add up? Is the Leica M8 better than the Nikon D300S or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Leica M8:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• More compact: Is smaller (139x80mm vs 147x115mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 347g or 37 percent) and hence easier to carry around.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More heavily discounted: Has been available for much longer (launched in September 2006).

Arguments in favor of the Nikon D300S:

• More detail: Has more megapixels (12.2 vs 10.4MP), which boosts linear resolution by 9%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
• Broader imaging potential: Can capture not only stills but also 720/24p video.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
• Faster burst: Shoots at higher frequency (7 vs 2 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Longer lasting: Gets more shots (950 versus 550) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was introduced into a lower priced category (67 percent cheaper at launch).
• More modern: Reflects 2 years and 10 months of technical progress since the M8 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D300S 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 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the M8 or the D300S perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
