Nikon D70s vs Panasonic ZS100

The Nikon D70s and the Panasonic Lumix DMC-ZS100 (labelled Panasonic TZ100 in some countries) are two digital cameras that were announced, respectively, in April 2005 and January 2016. The D70s is a DSLR, while the ZS100 is a fixed lens compact. The cameras are based on an APS-C (D70s) and an one-inch (ZS100) sensor. The Nikon has a resolution of 6 megapixels, whereas the Panasonic provides 20 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 Panasonic Lumix DMC-ZS100? 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 physical size and weight of the Nikon D70s and the Panasonic ZS100 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.

The ZS100 can be obtained in two different colors (black, silver), while the D70s is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic ZS100 is considerably smaller (54 percent) than the Nikon D70s. In this context, it is worth noting that neither the D70s nor the ZS100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the ZS100 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 ZS100 can take 300 images on a single charge of its Panasonic DMW-BLG10 power pack. The power pack in the ZS100 can be charged via the USB port, which can be very convenient when travelling.

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 ZS100 was launched at a lower price than the D70s, 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.

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.

Of the two cameras under consideration, the Nikon D70s features an APS-C sensor and the Panasonic ZS100 an one-inch sensor. The sensor area in the ZS100 is 69 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the ZS100 offers a higher resolution of 20 megapixels, compared with 6 MP of the D70s. 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 2.41μm versus 7.85μm for the D70s). However, it should be noted that the ZS100 is much more recent (by 10 years and 8 months) than the D70s, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Panasonic ZS100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the ZS100 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 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 Panasonic Lumix DMC-ZS100 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

In terms of underlying technology, the D70s is build around a CCD sensor, while the ZS100 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.

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 ZS100 offers substantially better image quality than the D70s (overall score 20 points higher). The advantage is based on 2.4 bits higher color depth, 2.2 EV in additional dynamic range, and 0.1 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: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The ZS100 indeed provides for movie recording, while the D70s does not. The highest resolution format that the ZS100 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 ZS100 has an electronic viewfinder (1166k 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 ZS100 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. On the other hand, the viewfinder of the D70s has a higher magnification (0.50x vs 0.46x), 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 Panasonic ZS100 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 differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The ZS100 has a touchscreen, while the D70s 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 ZS100 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 ZS100 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 D70s writes its imaging data to Compact Flash cards, while the ZS100 uses SDXC 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 Panasonic Lumix DMC-ZS100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D70s has a hotshoe, while the ZS100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the D70s and the ZS100 have been discontinued, but can regularly be found used on ebay. The D70s was replaced by the Nikon D80, while the ZS100 was followed by the Panasonic ZS200. Further information on the features and operation of the D70s and ZS100 can be found, respectively, in the Nikon D70s Manual (free pdf) or the online Panasonic ZS100 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Nikon D70s or the Panasonic ZS100 – has the upper hand? Is one clearly better than the other? 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 individual advantages (bullet points above) is taken as a guide, the ZS100 is the clear winner of the contest (21 : 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.

How about other alternatives? Do the specifications of the Nikon D70s and the Panasonic ZS100 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D70s or the ZS100. 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.
