Nikon D70 vs Sony A850
The Nikon D70 and the Sony Alpha A850 are two digital cameras that were officially introduced, respectively, in January 2004 and August 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D70) and a full frame (A850) sensor. The Nikon has a resolution of 6 megapixels, whereas the Sony provides 24.4 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 D70 and the Sony Alpha A850? 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 D70 and the Sony A850 is provided in the side-by-side display below. 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 measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A850 is notably larger (17 percent) than the Nikon D70. Moreover, the A850 is markedly heavier (32 percent) than the D70. It is noteworthy in this context that the A850 is splash and dust-proof, while the D70 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. 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 D70 gets 400 shots out of its Nikon EN-EL3 battery, while the A850 can take 880 images on a single charge of its Sony NP-FM500H power pack.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

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 D70 was launched at a markedly lower price (by 50 percent) than the A850, 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 size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 Nikon D70 features an APS-C sensor and the Sony A850 a full frame sensor. The sensor area in the A850 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.
With 24.4MP, the A850 offers a higher resolution than the D70 (6MP), but the A850 has smaller individual pixels (pixel pitch of 5.94μm versus 7.85μm for the D70). Yet, the A850 is a much more recent model (by 5 years and 7 months) than the D70, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony A850 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A850 for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inches or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inches or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inches or 51.2 x 34.1 cm. The corresponding values for the Nikon D70 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.
The Nikon D70 has a native sensitivity range from ISO 200 to ISO 1600. The corresponding ISO settings for the Sony Alpha A850 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.
In terms of underlying technology, the D70 is build around a CCD sensor, while the A850 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.
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the A850 offers substantially better image quality than the D70 (overall score 29 points higher). The advantage is based on 3.4 bits higher color depth, 1.9 EV in additional dynamic range, and 1.4 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.

Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. The D70 and the A850 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the A850 offers a wider field of view (98%) than the one in the D70 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A850 has a higher magnification (0.74x vs 0.50x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D70 and Sony A850 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The D70 has one, while the A850 does not. While the built-in flash of the D70 is not very powerful, it can at times be useful as a fill-in light.
The D70 writes its imaging data to Compact Flash cards, while the A850 uses Compact Flash or Memory Stick PRO Duo cards. The A850 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D70 only has one slot.
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 D70 and Sony Alpha A850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Sony A850 (unlike the D70) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D70 and the A850 have been discontinued, but can regularly be found used on ebay. The D70 was replaced by the Nikon D70s, while the A850 does not have a direct successor. Further information on the features and operation of the D70 and A850 can be found, respectively, in the Nikon D70 Manual (free pdf) or the online Sony A850 Manual.
Review summary
So what is the bottom line? Which of the two cameras – the Nikon D70 or the Sony A850 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Nikon D70:
- More compact: Is smaller (140x111mm vs 156x117mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 216g or 24 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in January 2004).
Advantages of the Sony Alpha A850:
- More detail: Has more megapixels (24.4 vs 6MP), which boosts linear resolution by 101%.
- Better image quality: Scores substantially higher (29 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (3.4 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.4 stops ISO advantage).
- More complete view: Has a viewfinder with a larger field of view (98% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.50x).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (922k vs 130k dots).
- Longer lasting: Gets more shots (880 versus 400) 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.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.0).
- 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.
- More modern: Reflects 5 years and 7 months of technical progress since the D70 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the A850 is the clear winner of the contest (17 : 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 D70 and the Sony A850 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the D70 or the A850 perform in practice. 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.

The review scores listed above should be treated 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.
