Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D70s 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 Nikon D70s and the Zeiss ZX1. 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.

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 (15 percent) than the Nikon D70s. In this context, it is worth noting that neither the D70s nor the ZX1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the ZX1 has a lens built in, whereas the D70s 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 D70s and their specifications in the Nikon Lens Catalog.

Concerning battery life, the D70s gets 500 shots out of its Nikon EN-EL3a battery, while the ZX1 can take 250 images on a single charge of its Zeiss DD-PS1A power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. 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. 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 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 D70s features an APS-C sensor and the Zeiss ZX1 a full frame sensor. The sensor area in the ZX1 is 134 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 37.4MP, the ZX1 offers a higher resolution than the D70s (6MP), but the ZX1 has smaller individual pixels (pixel pitch of 4.81μm versus 7.85μm for the D70s). Yet, the ZX1 is a much more recent model (by 13 years and 5 months) than the D70s, 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 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 inches or 95.1 x 63.4 cm, for very good quality (250 dpi) 30 x 20 inches or 76.1 x 50.7 cm, and for excellent quality (300 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm. The corresponding values for the Nikon D70s 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 D70s has a native sensitivity range from ISO 200 to ISO 1600. The corresponding ISO settings for the Zeiss ZX1 are ISO 80 to ISO 51200 (no boost).

In terms of underlying technology, the D70s is build around a CCD 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The ZX1 indeed provides for movie recording, while the D70s does not. The highest resolution format that the ZX1 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the ZX1 has an electronic viewfinder (6221k 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 ZX1 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 ZX1 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 D70s and Zeiss ZX1 in connection with corresponding information for a sample of similar cameras.

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

One difference between the cameras concerns the presence of an on-board flash. The D70s has one, while the ZX1 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 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 D70s writes its imaging data to Compact Flash 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 Nikon D70s 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 ZX1 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 provide wifi capability.

Both the D70s and the ZX1 have been discontinued, but can regularly be found used on ebay. The D70s was replaced by the Nikon D80, while the ZX1 does not have a direct successor. Further information on the features and operation of the D70s and ZX1 can be found, respectively, in the Nikon D70s Manual (free pdf) or the online Zeiss ZX1 Manual.

Review summary

So how do things add up? Is the Nikon D70s better than the Zeiss ZX1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Nikon D70s:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.

If the count of relative strengths (bullet points above) is taken as a measure, the ZX1 is the clear winner of the contest (21 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D70s or the ZX1. 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 (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.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
