Nikon D70s vs Sony A7S II

The Nikon D70s and the Sony Alpha 7S II are two digital cameras that were announced, respectively, in April 2005 and September 2015. The D70s is a DSLR, while the A7S II is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D70s) and a full frame (A7S II) sensor. The Nikon has a resolution of 6 megapixels, whereas the Sony provides 12 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 Nikon D70s and the Sony Alpha 7S 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

An illustration of the physical size and weight of the Nikon D70s and the Sony A7S II 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.

Compare D70s versus A7S II top
Comparison D70s or A7S II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7S II is notably smaller (22 percent) than the Nikon D70s. Moreover, the A7S II is markedly lighter (8 percent) than the D70s. It is noteworthy in this context that the A7S II is splash and dust-proof, while the D70s 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D70s) and the Sony FE Lens Catalog (A7S II). Mirrorless cameras, such as the A7S II, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the D70s gets 500 shots out of its EN-EL3a battery, while the A7S II can take 370 images on a single charge of its NP-FW50 power pack. The power pack in the A7S II can be charged via the USB port, which can be very convenient when travelling.

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

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D70s was launched at a markedly lower price (by 70 percent) than the A7S II, 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

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.

Of the two cameras under consideration, the Nikon D70s features an APS-C sensor and the Sony A7S II a full frame sensor. The sensor area in the A7S II is 129 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.

Nikon D70s and Sony A7S II sensor measures

With 12MP, the A7S II offers a higher resolution than the D70s (6MP), but the A7S II nevertheless has larger individual pixels (pixel pitch of 8.40μm versus 7.85μm for the D70s) due to its larger sensor. Moreover, the A7S II is a much more recent model (by 10 years and 4 months) than the D70s, 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 Sony A7S II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7S II for good quality output (200 dots per inch) amounts to 21.2 x 14.2 inch or 53.8 x 36 cm, for very good quality (250 dpi) 17 x 11.3 inch or 43.1 x 28.8 cm, and for excellent quality (300 dpi) 14.1 x 9.4 inch or 35.9 x 24 cm. The corresponding values for the Nikon D70s are 15 x 10 inch or 38.2 x 25.4 cm for good quality, 12 x 8 inch or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inch or 25.5 x 16.9 cm for excellent quality prints.

The Nikon D70s has a native sensitivity range from ISO 200 to ISO 1600. The corresponding ISO settings for the Sony Alpha 7S II are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-409600.

D70s versus A7S II MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under consideration, the A7S II offers substantially better image quality than the D70s (overall score 35 points higher). The advantage is based on 3.2 bits higher color depth, 3 EV in additional dynamic range, and 2.5 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The A7S II indeed provides for movie recording, while the D70s does not. The highest resolution format that the A7S 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 A7S II has an electronic viewfinder (2400k dots), while the D70s has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the A7S II offers a wider field of view (100%) than the one in the D70s (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A7S II has a higher magnification (0.78x vs 0.50x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D70s and Sony A7S II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D70s has one, while the A7S II does not. While the built-in flash of the D70s is not very powerful, it can at times be useful as a fill-in light.

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 A7S II 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 D70s writes its imaging data to Compact Flash cards, while the A7S II uses SDXC or Memory Stick PRO Duo 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 Nikon D70s and Sony Alpha 7S II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7S II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D70s does not offer wifi capability.

The A7S II is a recent model that features in the current product line-up of Sony. In contrast, the D70s has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the D70s was succeeded by the Nikon D80. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Sony websites.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Nikon D70s and the Sony A7S II? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Nikon D70s:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Longer lasting: Can take more shots (500 versus 370) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in April 2005).

ilogo

Arguments in favor of the Sony Alpha 7S II:

  • More detail: Has more megapixels (12 vs 6MP), which boosts linear resolution by 41%.
  • Better image quality: Scores substantially higher (35 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (3.2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.5 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.50x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 130k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (127x96mm vs 140x111mm) and will fit more readily into a bag.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • 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.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • 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.
  • More modern: Reflects 10 years and 4 months of technical progress since the D70s launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A7S II is the clear winner of the contest (21 : 5 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 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.

How about other alternatives? Do the specifications of the Nikon D70s and the Sony A7S II place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D70s or the A7S II. 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Care should be taken when interpreting the review scores above, 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
