Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M9 and the Nikon D5? 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 Leica M9 and the Nikon D5 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 M9 can be obtained in two different colors (black, silver), while the D5 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 D5 is considerably larger (129 percent) than the Leica M9. Moreover, the D5 is substantially heavier (142 percent) than the M9. It is noteworthy in this context that the D5 is splash and dust-proof, while the M9 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Leica M Lens Catalog (M9) and the Nikon Lens Catalog (D5).

Concerning battery life, the M9 gets 550 shots out of its Leica BLI-312 battery, while the D5 can take 3780 images on a single charge of its Nikon EN-EL18a power pack. As can be seen in the images above, the D5 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The price is, of course, an important factor in any camera decision. 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 D5 was launched at a somewhat lower price (by 19 percent) than the M9, which makes it more attractive for photographers on a tight budget. 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 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the D5 is 1 percent smaller. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a slightly smaller sensor, the D5 offers a higher resolution of 20.7 megapixels, compared with 18.1 MP of the M9. 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 6.44μm versus 6.91μm for the M9). However, it should be noted that the D5 is much more recent (by 6 years and 3 months) than the M9, 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 M9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon D5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D5 for good quality output (200 dots per inch) amounts to 27.9 x 18.6 inches or 71 x 47.1 cm, for very good quality (250 dpi) 22.4 x 14.8 inches or 56.8 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inches or 47.3 x 31.4 cm. The corresponding values for the Leica M9 are 26.1 x 17.4 inches or 66.2 x 44.1 cm for good quality, 20.8 x 13.9 inches or 53 x 35.3 cm for very good quality, and 17.4 x 11.6 inches or 44.1 x 29.4 cm for excellent quality prints.

The Leica M9 has a native sensitivity range from ISO 80 to ISO 2500. The corresponding ISO settings for the Nikon D5 are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-3280000.

In terms of underlying technology, the M9 is build around a CCD sensor, while the D5 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 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 D5 offers substantially better image quality than the M9 (overall score 19 points higher). The advantage is based on 2.6 bits higher color depth, 0.6 EV in additional dynamic range, and 1.4 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.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D5 indeed provides for movie recording, while the M9 does not. The highest resolution format that the D5 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The M9 and the D5 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the D5 has a higher magnification than the one of the M9 (0.72x vs 0.68x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Leica M9 and Nikon D5 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The D5 has a touchscreen, while the M9 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Nikon D5 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 M9 writes its imaging data to SDXC cards, while the D5 uses Compact Flash or XQD cards. The D5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the M9 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 M9 and Nikon D5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D5 (unlike the M9) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the M9 and the D5 have been discontinued, but can regularly be found used on ebay. The M9 was replaced by the Leica M Typ 240, while the D5 was followed by the Nikon D6. Further information on the features and operation of the M9 and D5 can be found, respectively, in the Leica M9 Manual (free pdf) or the online Nikon D5 Manual.

Review summary

So how do things add up? Is the Leica M9 better than the Nikon D5 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Leica M9:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• More compact: Is smaller (139x80mm vs 160x159mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 830g or 59 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 2009).

Reasons to prefer the Nikon D5:

• More detail: Has more megapixels (20.7 vs 18.1MP), which boosts linear resolution by 7%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Scores substantially higher (19 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (2.6 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (1.4 stops ISO advantage).
• Broader imaging potential: Can capture not only stills but also 4K/30p video.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.72x vs 0.68x).
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Larger screen: Has a bigger rear LCD (3.2" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (2359k vs 230k 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 (14 vs 2 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (3780 versus 550) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• 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 released into a lower priced segment (19 percent cheaper at launch).
• More modern: Reflects 6 years and 3 months of technical progress since the M9 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the D5 is the clear winner of the contest (23 : 5 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the M9 or the D5. 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.

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

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
