Leica M10-P vs Nikon D100

The Leica M10-P and the Nikon D100 are two enthusiast cameras that were announced, respectively, in August 2018 and February 2002. The M10-P is a rangefinder-style mirrorless camera, while the D100 is a DSLR. The cameras are based on a full frame (M10-P) and an APS-C (D100) sensor. The Leica has a resolution of 23.8 megapixels, whereas the Nikon provides 6 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 Leica M10-P and the Nikon D100? 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 M10-P and the Nikon D100. 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 dimensions are rounded to the nearest millimeter.

The M10-P can be obtained in two different colors (black, silver), while the D100 is only available in black.

Compare M10-P versus D100 top
Comparison M10-P or D100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D100 is considerably larger (50 percent) than the Leica M10-P. Moreover, the D100 is markedly heavier (18 percent) than the M10-P. It is worth mentioning in this context that the M10-P is splash and dust resistant, while the D100 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 (M10-P) and the Nikon Lens Catalog (D100).

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D100 was launched at a markedly lower price (by 75 percent) than the M10-P, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 M10-P features a full frame sensor and the Nikon D100 an APS-C sensor. The sensor area in the D100 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Leica M10-P and Nikon D100 sensor measures

With 23.8MP, the M10-P offers a higher resolution than the D100 (6MP), but the M10-P has smaller individual pixels (pixel pitch of 6.00μm versus 7.85μm for the D100). However, the M10-P is a much more recent model (by 16 years and 6 months) than the D100, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the M10-P has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica M10-P implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10-P for good quality output (200 dots per inch) amounts to 29.8 x 20 inches or 75.6 x 50.7 cm, for very good quality (250 dpi) 23.8 x 16 inches or 60.5 x 40.6 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.8 cm. The corresponding values for the Nikon D100 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.

The Leica M10-P has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Nikon D100 are ISO 200 to ISO 800, with the possibility to increase the ISO range to 200-1600.

M10-P versus D100 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The M10-P and the D100 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 M10-P offers a wider field of view (100%) than the one in the D100 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the M10-P has a higher magnification (0.73x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Leica M10-P and Nikon D100 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M10-P has a touchscreen, while the D100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Leica M10-P 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 M10-P writes its imaging data to SDXC cards, while the D100 uses Compact Flash cards.

It is notable that the M10-P offers wifi support, while the D100 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The M10-P is a recent model that features in the current product line-up of Leica. In contrast, the D100 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D100 was succeeded by the Nikon D200. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Nikon websites.

Review summary

So how do things add up? Which of the two cameras – the Leica M10-P or the Nikon D100 – 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.

ilogo

Advantages of the Leica M10-P:

  • More detail: Offers more megapixels (23.8 vs 6MP) with a 98% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • 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.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.53x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 118k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (139x80mm vs 144x116mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 120g or 15 percent) and hence easier to carry around.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
  • More modern: Reflects 16 years and 6 months of technical progress since the D100 launch.

ilogo

Arguments in favor of the Nikon D100:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Longer lasting: Gets more shots (370 versus 210) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in February 2002).

If the count of relative strengths (bullet points above) is taken as a measure, the M10-P is the clear winner of the match-up (19 : 6 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

M10-P 19:06 D100

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 M10-P or the D100 perform in practice. 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], 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.

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

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
