Leica M9 vs Nikon L840

The Leica M9 and the Nikon Coolpix L840 are two digital cameras that were officially introduced, respectively, in September 2009 and February 2015. The M9 is a rangefinder-focusing mirrorless camera, while the L840 is a fixed lens compact. The cameras are based on a full frame (M9) and a 1/2.3-inch (L840) sensor. The Leica has a resolution of 18.1 megapixels, whereas the Nikon provides 15.9 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Leica M9 and the Nikon L840. 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 dimensions are rounded to the nearest millimeter.

The M9 can be obtained in two different colors (black, silver), while the L840 is also available in two color-versions, but different ones (black, red).

Size Leica M9 vs Nikon L840
Compare M9 versus L840 top
Comparison M9 or L840 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon L840 is notably smaller (21 percent) than the Leica M9. In this context, it is worth noting that neither the M9 nor the L840 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the L840 has a lens built in, whereas the M9 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the M9 and their specifications in the Leica M Lens Catalog.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The L840 was launched at a lower price than the M9, despite having a lens built in. 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.

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. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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.

Of the two cameras under consideration, the Leica M9 features a full frame sensor and the Nikon L840 a 1/2.3-inch sensor. The sensor area in the L840 is 97 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 5.6. The sensor in the M9 has a native 3:2 aspect ratio, while the one in the L840 offers a 4:3 aspect.

Leica M9 and Nikon L840 sensor measures

With 18.1MP, the M9 offers a higher resolution than the L840 (15.9MP), but the M9 nevertheless has larger individual pixels (pixel pitch of 6.91μm versus 1.33μm for the L840) due to its larger sensor. However, the L840 is a much more recent model (by 5 years and 5 months) than the M9, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Leica M9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M9 for good quality output (200 dots per inch) amounts to 26.1 x 17.4 inches or 66.2 x 44.1 cm, for very good quality (250 dpi) 20.8 x 13.9 inches or 53 x 35.3 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inches or 44.1 x 29.4 cm. The corresponding values for the Nikon L840 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 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 Coolpix L840 are ISO 100 to ISO 6400 (no boost).

In terms of underlying technology, the M9 is build around a CCD sensor, while the L840 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.

M9 versus L840 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 variety of features. For example, the M9 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the L840 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Leica M9 and Nikon L840 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The L840 has one, while the M9 does not. While the built-in flash of the L840 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the M9 and the L840 write their files to SDXC cards.

It is notable that the M9 has a hotshoe, while the L840 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the M9 and the L840 have been discontinued, but can regularly be found used on ebay. The M9 was replaced by the Leica M Typ 240, while the L840 was followed by the Nikon B500. Further information on the features and operation of the M9 and L840 can be found, respectively, in the Leica M9 Manual (free pdf) or the online Nikon L840 Manual.

Review summary

So what conclusions can be drawn? Is the Leica M9 better than the Nikon L840 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Leica M9:

  • More detail: Offers more megapixels (18.1 vs 15.9MP) with a 9% higher linear resolution.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • 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).

ilogo

Advantages of the Nikon Coolpix L840:

  • Broader imaging potential: Can capture not only stills but also 1080/60i video.
  • 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 (921k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (7.4 vs 2 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the M9 necessitates an extra lens.
  • More compact: Is smaller (113x78mm vs 139x80mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the M9).
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 5 years and 5 months of technical progress since the M9 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the L840 is the clear winner of the contest (14 : 10 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.

M9 10:14 L840

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 L840. 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 expert reviews 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.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
