Leica M Typ 240 versus Sony A7

The Leica M (Typ 240) and the Sony Alpha A7 are two enthusiast cameras that were officially introduced, respectively, in September 2012 and October 2013. The M Typ 240 is a fixed lens compact, while the A7 is a rangefinder-style mirrorless. Both cameras are equipped with a full frame sensor. The Leica has a resolution of 23.7 megapixel, whereas the Sony provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Leica M Typ 240 vs Sony A7

The side-by-side display below illustrates the physical size and weight of the Leica M Typ 240 and the Sony A7. 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the M Typ 240 – 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 Sony A7 is notably larger (7 percent) than the Leica M Typ 240. However, the A7 is markedly lighter (30 percent) than the M Typ 240. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 find an overview of optics for the two cameras in the Leica M Lens Catalog (M Typ 240) and the Sony FE Lens Catalog (A7).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A7 was launched at a markedly lower price (by 76 percent) than the M Typ 240, 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: Leica M Typ 240 vs Sony A7

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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of underlying technology, both cameras are build around CMOS sensors.

Leica M Typ 240 and Sony A7 sensor measures

While the two cameras under review share the same sensor size, the A7 offers a slightly higher resolution of 24 megapixel, compared with 23.7 MP of the M Typ 240. This megapixel advantage translates into a 0.8 percent gain in linear resolution. On the other hand, these sensor specs imply that the A7 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.97μm versus 6.01μm for the M Typ 240). However, it should be noted that the A7 is a somewhat more recent model (by 1 year) than the M Typ 240, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

M Typ 240 versus A7 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under consideration, the A7 has a markedly higher DXO score than the M Typ 240 (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 0.9 EV in additional dynamic range, and 0.3 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7 provides a faster frame rate than the M Typ 240. It can shoot movie footage at 1080/60p, while the Leica is limited to 1080/25p.

 

Feature comparison: Leica M Typ 240 vs Sony A7

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7 has an electronic viewfinder (2400k dots), while the M Typ 240 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The following table reports on some other key feature differences and similarities of the Leica M Typ 240, the Sony A7, and comparable cameras.

Review summary: Leica M Typ 240 vs Sony A7

So how do things add up? Which of the two cameras – the Leica M Typ 240 or the Sony A7 – has the upper hand? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Leica M (Typ 240):

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
  • More heavily discounted: Has been on the market for longer (launched in September 2012).

ilogo

Arguments in favor of the Sony Alpha A7:

  • Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/25p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 920k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • Less heavy: Has a lower weight (by 206g or 30 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (76 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the A7 is the clear winner of the contest (11 : 3 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.

M Typ 240 03:11 A7

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the M Typ 240 and the A7 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, 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.
