Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha SLT-A77 II and the Zeiss ZX1? 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 Sony A77 II and the Zeiss ZX1. 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.

Compare A77 II versus ZX1 top
Comparison A77 II or ZX1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Zeiss ZX1 is notably smaller (11 percent) than the Sony A77 II. It is worth mentioning in this context that the A77 II is splash and dust resistant, while the ZX1 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the ZX1 has a lens built in, whereas the A77 II is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

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.

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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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 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 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony A77 II features an APS-C sensor and the Zeiss ZX1 a full frame sensor. The sensor area in the ZX1 is 135 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.

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

Sony A77 II and Zeiss ZX1 sensor measures

With 37.4MP, the ZX1 offers a higher resolution than the A77 II (24MP), but the ZX1 nevertheless has larger individual pixels (pixel pitch of 4.81μm versus 3.91μm for the A77 II) due to its larger sensor. Moreover, the ZX1 is a much more recent model (by 4 years and 4 months) than the A77 II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Zeiss ZX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the ZX1 for good quality output (200 dots per inch) amounts to 37.4 x 25 inch or 95.1 x 63.4 cm, for very good quality (250 dpi) 30 x 20 inch or 76.1 x 50.7 cm, and for excellent quality (300 dpi) 25 x 16.6 inch or 63.4 x 42.3 cm. The corresponding values for the Sony A77 II are 30 x 20 inch or 76.2 x 50.8 cm for good quality, 24 x 16 inch or 61 x 40.6 cm for very good quality, and 20 x 13.3 inch or 50.8 x 33.9 cm for excellent quality prints.

The Sony Alpha SLT-A77 II has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-51200. The corresponding ISO settings for the Zeiss ZX1 are ISO 80 to ISO 51200 (no boost).

A77 II versus ZX1 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the ZX1 provides a better video resolution than the A77 II. It can shoot movie footage at 4K/30p, while the Sony is limited to 1080/60p.

 

Feature comparison

Apart from 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 ZX1 offers a substantially higher resolution than the one in the A77 II (6221k vs 2359k dots).

One difference between the cameras concerns the presence of an on-board flash. The A77 II has one, while the ZX1 does not. While the built-in flash of the A77 II is not very powerful, it can at times be useful as a fill-in light.

The A77 II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the ZX1 does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the ZX1 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The A77 II writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the ZX1 uses an internal SSD.

 

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 Sony Alpha SLT-A77 II and Zeiss ZX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A77 II has a microphone port, which is missing on the ZX1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Studio photographers will appreciate that the Sony A77 II (unlike the ZX1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the A77 II and the ZX1 are recent models that are part of the current product line-up. The A77 II replaced the earlier Sony A77, while the ZX1 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony and Zeiss websites.


Review summary

So how do things add up? Is the Sony A77 II better than the Zeiss ZX1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Ready to shoot: Comes with an integrated lens, while the A77 II requires a separate lens.
  • More compact: Is smaller (142x93mm vs 143x104mm) and will fit more readily into a bag.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More prestigious: Has the Zeiss luxury appeal, which ensures a high resale value.

If the number of relative strengths (bullet points above) is taken as a guide, the ZX1 is the clear winner of the contest (17 : 11 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.

A77 II 11:17 ZX1

How about other alternatives? Do the specifications of the Sony A77 II and the Zeiss ZX1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.

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 A77 II or the ZX1 perform in practice. 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 hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
