Leica CL versus Sony A7
The Leica CL (Typ 7323) and the Sony Alpha A7 are two digital cameras that were officially introduced, respectively, in November 2017 and October 2013. Both the CL and the A7 are mirrorless interchangeable lens cameras that are based on an APS-C (CL) and a full frame (A7) sensor. The Leica has a resolution of 24.1 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 CL vs Sony A7
The physical size and weight of the Leica CL and the Sony A7 are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size 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 CL – represents 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 (17 percent) than the Leica CL. Moreover, the A7 is markedly heavier (18 percent) than the CL. It is noteworthy in this context that the A7 is splash and dust-proof, while the CL 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
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 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 A7 was launched at a markedly lower price (by 39 percent) than the CL, 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: Leica CL vs Sony A7
The size of the sensor inside a digital camera is one of the key determinants 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 CL features an APS-C sensor and the Sony A7 a full frame sensor. The sensor area in the A7 is 131 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Leica CL offers a higher resolution of 24.1 megapixel, compared with 24 MP of the Sony A7. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.92μm versus 5.97μm for the A7). However, it should be noted that the CL is much more recent (by 4 years and 1 month) than the A7, 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 CL has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 CL provides a higher video resolution than the A7. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60p.
Feature comparison: Leica CL vs Sony A7
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A7 offers a slightly higher resolution than the one in the CL (2400k vs 2360k dots).

The CL is a current model that online retailers, such as amazon, will have in stock. In contrast, the A7 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7 was succeeded by the Sony A7 II.
Review summary: Leica CL vs Sony A7
So how do things add up? Which of the two cameras – the Leica CL or the Sony A7 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Leica CL (Typ 7323):
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Easier setting verification: Has an LCD display on top to control shooting parameters.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (131x78mm vs 127x94mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 71g or 15 percent) and hence easier to carry around.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
- More modern: Reflects 4 years and 1 month of technical progress since the A7 launch.
Arguments in favor of the Sony Alpha A7:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More detailed LCD: Has a higher resolution rear screen (1230k vs 1040k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Longer lasting: Gets more shots (340 versus 220) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in October 2013).
If the count of individual advantages (bullet points above) is taken as a guide, the CL emerges as the winner of the contest (9 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the CL or the A7 handle or perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is where reviews by experts come in.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
