Body comparison

An illustration of the physical size and weight of the Sony A1 and the Zeiss ZX1 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

Size Sony A1 vs Zeiss ZX1
Compare A1 versus ZX1 top
Comparison A1 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 larger (6 percent) than the Sony A1. It is worth mentioning in this context that the A1 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 A1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the A1 and their specifications in the Sony FE Lens Catalog.

Concerning battery life, the A1 gets 530 shots out of its Sony NP-FZ100 battery, while the ZX1 can take 250 images on a single charge of its Zeiss DD-PS1A power pack. The power pack in the A1 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or 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. The ZX1 was launched at a lower price than the A1, despite having a lens built in. 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 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A1 and Zeiss ZX1 sensor measures

Despite having a slightly smaller sensor, the Sony A1 offers a higher resolution of 49.8 megapixels, compared with 37.4 MP of the Zeiss ZX1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.16μm versus 4.81μm for the ZX1). However, it should be noted that the A1 is much more recent (by 2 years and 4 months) than the ZX1, 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 A1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A1 for good quality output (200 dots per inch) amounts to 43.2 x 28.8 inches or 109.7 x 73.2 cm, for very good quality (250 dpi) 34.6 x 23 inches or 87.8 x 58.5 cm, and for excellent quality (300 dpi) 28.8 x 19.2 inches or 73.2 x 48.8 cm. The corresponding values for the Zeiss ZX1 are 37.4 x 25 inches or 95.1 x 63.4 cm for good quality, 30 x 20 inches or 76.1 x 50.7 cm for very good quality, and 25 x 16.6 inches or 63.4 x 42.3 cm for excellent quality prints.

The A1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the ZX1, the A1 has the capacity to capture high quality composite images (YESMP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Sony A1 has a native sensitivity range from ISO 100 to ISO 32000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Zeiss ZX1 are ISO 80 to ISO 51200 (no boost).

In terms of underlying technology, the A1 is build around a Stacked BSI-CMOS sensor, while the ZX1 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

A1 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. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

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, both cameras under consideration feature an 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 Sony A1 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The A1 writes its imaging data to CFexpress (type A) or SDXC cards, while the ZX1 uses an internal SSD.

It is notable that the A1 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 A1 (unlike the ZX1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A1 is a recent model that features in the current product line-up of Sony. In contrast, the ZX1 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the ZX1 from Zeiss. Further information on the features and operation of the A1 and ZX1 can be found, respectively, in the Sony A1 Manual (free pdf) or the online Zeiss ZX1 Manual.

  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (9437k vs 6221k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.9x vs 0.74x).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/1000s) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Longer lasting: Can take more shots (530 versus 250) on a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.

  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More modern: Reflects 2 years and 4 months of technical progress since the ZX1 launch.

ilogo

Arguments in favor of the Zeiss ZX1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Larger screen: Has a bigger rear LCD (4.3" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2765k vs 1440k dots).
  • Ready to shoot: Has an integrated lens, whereas the A1 necessitates an extra lens.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More prestigious: Has the Zeiss luxury appeal, which ensures a high resale value.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been around for much longer (launched in September 2018).

If the count of relative strengths (bullet points above) is taken as a measure, the A1 is the clear winner of the match-up (22 : 8 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 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.

A1 22:08 ZX1

How about other alternatives? Do the specifications of the Sony A1 and the Zeiss ZX1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the A1 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 expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
