Leica X1 vs Sony A99 II

The Leica X1 and the Sony Alpha ALT-A99 II are two digital cameras that were announced, respectively, in September 2009 and September 2016. The X1 is a fixed lens compact, while the A99 II is a DSLR. The cameras are based on an APS-C (X1) and a full frame (A99 II) sensor. The Leica has a resolution of 12.2 megapixels, whereas the Sony provides 42.2 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 X1 and the Sony Alpha ALT-A99 II? 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 X1 and the Sony A99 II. 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 size dimensions are rounded to the nearest millimeter.

The X1 can be obtained in two different colors (black, silver), while the A99 II is only available in black.

Size Leica X1 vs Sony A99 II
Compare X1 versus A99 II top
Comparison X1 or A99 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A99 II is considerably larger (100 percent) than the Leica X1. It is noteworthy in this context that the A99 II is splash and dust-proof, while the X1 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X1 has a lens built in, whereas the A99 II is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the X1 gets 260 shots out of its BP-DC8 battery, while the A99 II can take 490 images on a single charge of its NP-FM500H power pack.

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

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The X1 was launched at a lower price than the A99 II, 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. 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 X1 features an APS-C sensor and the Sony A99 II a full frame sensor. The sensor area in the A99 II is 133 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.

Leica X1 and Sony A99 II sensor measures

With 42.2MP, the A99 II offers a higher resolution than the X1 (12.2MP), but the A99 II has smaller individual pixels (pixel pitch of 4.52μm versus 5.51μm for the X1). Yet, the A99 II is a much more recent model (by 7 years) than the X1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the A99 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A99 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A99 II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inch or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inch or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inch or 67.3 x 44.9 cm. The corresponding values for the Leica X1 are 21.4 x 14.3 inch or 54.3 x 36.3 cm for good quality, 17.1 x 11.4 inch or 43.4 x 29 cm for very good quality, and 14.2 x 9.5 inch or 36.2 x 24.2 cm for excellent quality prints.

The A99 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Leica X1 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Sony Alpha ALT-A99 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-25600.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The A99 II indeed provides for movie recording, while the X1 does not. The highest resolution format that the A99 II can use is 4K/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A99 II has an electronic viewfinder (2400k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Leica X1 and Sony A99 II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The X1 has one, while the A99 II does not. While the built-in flash of the X1 is not very powerful, it can at times be useful as a fill-in light.

The A99 II has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the X1 does not have a selfie-screen.

The X1 writes its imaging data to SDHC cards, while the A99 II uses SDXC or Memory Stick PRO Duo cards. The A99 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the X1 only has one slot. The A99 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X1 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Leica X1 and Sony Alpha ALT-A99 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A99 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the X1 does not offer wifi capability.

Studio photographers will appreciate that the Sony A99 II (unlike the X1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A99 II is a recent model that features in the current product line-up of Sony. In contrast, the X1 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the X1 was succeeded by the Leica X2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Sony websites.

Review summary

So what is the bottom line? Which of the two cameras – the Leica X1 or the Sony A99 II – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Leica X1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Ready to shoot: Comes with a built-in lens, while the A99 II requires a separate lens.
  • More compact: Is smaller (124x60mm vs 143x104mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the A99 II).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been available for much longer (launched in September 2009).

ilogo

Advantages of the Sony Alpha ALT-A99 II:

  • More detail: Has more megapixels (42.2 vs 12.2MP), which boosts linear resolution by 86%.
  • 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.
  • 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.
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 230k dots).
  • More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (12 vs 3 flaps/sec) to capture the decisive moment.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (490 versus 260) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • 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.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 7 years of technical progress since the X1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A99 II is the clear winner of the contest (27 : 8 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

X1 08:27 A99 II

How about other alternatives? Do the specifications of the Leica X1 and the Sony A99 II place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the X1 and the A99 II in practical situations. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
