Body comparison

The physical size and weight of the Sony A7 and the Panasonic S1R are illustrated in the side-by-side display below. 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.

Size Sony A7 vs Panasonic S1R
Compare A7 versus S1R top
Comparison A7 or S1R rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1R is notably larger (37 percent) than the Sony A7. Moreover, the S1R is substantially heavier (114 percent) than the A7. 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the A7 gets 340 shots out of its Sony NP-FW50 battery, while the S1R can take 380 images on a single charge of its Panasonic DMW-BLJ31 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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

Any camera decision will naturally be influenced heavily by the price. 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 A7 was launched at a markedly lower price (by 54 percent) than the S1R, 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

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.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the S1R is 1 percent bigger. 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 A7 and Panasonic S1R sensor measures

With 46.7MP, the S1R offers a higher resolution than the A7 (24MP), but the S1R has smaller individual pixels (pixel pitch of 4.30μm versus 5.97μm for the A7). Yet, the S1R is a much more recent model (by 5 years and 3 months) than the A7, 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 S1R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic S1R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1R for good quality output (200 dots per inch) amounts to 41.8 x 27.9 inches or 106.3 x 70.9 cm, for very good quality (250 dpi) 33.5 x 22.3 inches or 85 x 56.7 cm, and for excellent quality (300 dpi) 27.9 x 18.6 inches or 70.8 x 47.3 cm. The corresponding values for the Sony A7 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The A7 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the A7, the S1R has the capacity to capture high quality composite images (187MP) 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 Alpha A7 has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-51200. The Panasonic Lumix DC-S1R offers exactly the same ISO settings.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

A7 versus S1R MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. Of the two cameras under consideration, the S1R has a markedly higher DXO score than the A7 (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1.6 bits higher color depth, 0.1 EV of lower dynamic range, and 0.6 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.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The S1R has a touchscreen, while the A7 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 S1R 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 Panasonic S1R 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 A7 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the S1R uses SDXC or XQD cards. The S1R features dual card slots, which can be very useful in case a memory card fails. In contrast, the A7 only has one slot. The S1R supports UHS-II cards (on both slots), while the A7 can use UHS-I cards.

Studio photographers will appreciate that the Panasonic S1R (unlike the A7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The S1R is a recent model that features in the current product line-up of Panasonic. In contrast, the A7 has been discontinued (but 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. Further information on the features and operation of the A7 and S1R can be found, respectively, in the Sony A7 Manual (free pdf) or the online Panasonic S1R Manual.

  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (54 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in October 2013).

ilogo

Reasons to prefer the Panasonic Lumix DC-S1R:

  • More detail: Has more megapixels (46.7 vs 24MP), which boosts linear resolution by 40%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
  • Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/60p vs 1080/60p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 2400k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.71x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2100k vs 1230k dots).
  • More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (9 vs 5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (380 versus 340) out of a single battery charge.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • 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: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 5 years and 3 months of technical progress since the A7 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the S1R is the clear winner of the contest (26 : 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. 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.

A7 07:26 S1R

How about other alternatives? Do the specifications of the Sony A7 and the Panasonic S1R place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the A7 or the S1R. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
