Leica Digilux 3 versus Leica M10

The Leica Digilux 3 and the Leica M10 (Typ 3656) are two digital cameras that were revealed to the public, respectively, in September 2006 and January 2017. The Digilux 3 is a DSLR, while the M10 is a rangefinder-style mirrorless camera. The cameras are based on a Four Thirds (Digilux 3) and a full frame sensor. The Digilux 3 has a resolution of 7.4 megapixel, whereas the M10 provides 23.8 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Leica Digilux 3 and the Leica M10. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the Digilux 3 – represents the basis or 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica M10 is notably smaller (12 percent) than the Leica Digilux 3. However, the M10 is slightly heavier (9 percent) than the Digilux 3. In this context, it is worth noting that neither the Digilux 3 nor the M10 are weather-sealed.

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 find an overview of optics for the two cameras in the Four Thirds Lens Catalog (Digilux 3) and the Leica M Lens Catalog (M10).

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, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Digilux 3 was launched at a markedly lower price (by 77 percent) than the M10, 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. 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 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. 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.

Of the two cameras under consideration, the Leica Digilux 3 features a Four Thirds sensor and the Leica M10 a full frame sensor. The sensor area in the M10 is 280 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the Digilux 3 has a native 4:3 aspect ratio, while the one in the M10 offers a 3:2 aspect.

Sensor size

With 23.8MP, the M10 offers a higher resolution than the Digilux 3 (7.4MP), but the M10 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 5.51μm for the Digilux 3) due to its larger sensor. Moreover, the M10 is a much more recent model (by 10 years and 4 months) than the Digilux 3, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Both the Digilux 3 and the M10 offer Live View, so that they make it possible to use the rear screen for framing. Both cameras are still-image focused and cannot record videos.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The Digilux 3 and the M10 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 adjacent table lists some of the other core features of the Leica Digilux 3 and Leica M10 along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The M10 is a current model that online retailers, such as amazon, will have in stock. In contrast, the Digilux 3 has been discontinued (but it can be found pre-owned on ebay). There has not been a direct replacement model for the Digilux 3 from Leica.

Summary

So what is the bottom line? Which of the two cameras – the Leica Digilux 3 or the Leica M10 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Leica Digilux 3:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Longer lasting: Can take more shots (750 versus 210) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2006).

Arguments in favor of the Leica M10 (Typ 3656):

  • More detail: Has more megapixels (23.8 vs 7.4MP), which boosts linear resolution by 83%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • 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 (1037k vs 207k dots).
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (139x80mm vs 146x87mm) and will fit more readily into a bag.
  • More modern: Reflects 10 years and 4 months of technical progress since the Digilux 3 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the M10 emerges as the winner of the match-up (8 : 5 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the Digilux 3 or the M10. 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. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
