Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D5100 and the Nikon D70? 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 D5100 and the Nikon D70 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D70 is notably larger (25 percent) than the Nikon D5100. Moreover, the D70 is markedly heavier (21 percent) than the D5100. In this context, it is worth noting that neither the D5100 nor the D70 are weather-sealed.

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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Nikon Lens Catalog.

Concerning battery life, the D5100 gets 660 shots out of its Nikon EN-EL14 battery, while the D70 can take 400 images on a single charge of its Nikon EN-EL3 power pack.

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.

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 D5100 was launched at a somewhat lower price (by 25 percent) than the D70, which makes it more attractive for photographers on a tight budget. 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. 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 associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 16.1MP, the D5100 offers a higher resolution than the D70 (6MP), but the D5100 has smaller individual pixels (pixel pitch of 4.80μm versus 7.85μm for the D70). However, the D5100 is a much more recent model (by 7 years and 2 months) than the D70, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Nikon D5100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D5100 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 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 D5100 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Nikon D70 are ISO 200 to ISO 1600 (no boost).

In terms of underlying technology, the D5100 is build around a CMOS sensor, while the D70 uses a CCD 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 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 review, the D5100 provides substantially higher image quality than the D70, with an overall score that is 30 points higher. This advantage is based on 3.1 bits higher color depth, 3.3 EV in additional dynamic range, and 1.2 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.

Many modern cameras cannot only take still pictures, but also record videos. The D5100 indeed provides movie recording capabilities, while the D70 does not. The highest resolution format that the D5100 can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D5100 and the D70 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the D5100 has a higher magnification than the one of the D70 (0.51x 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 D5100 and Nikon D70 in connection with corresponding information for a sample of similar cameras.

The Nikon D5100 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 D5100 writes its imaging data to SDXC cards, while the D70 uses Compact Flash 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 D5100 and Nikon D70 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D5100 and the D70 have been discontinued, but can regularly be found used on ebay. The D70 was replaced by the Nikon D70s, while the D5100 was followed by the Nikon D5200. Further information on the features and operation of the D5100 and D70 can be found, respectively, in the Nikon D5100 Manual (free pdf) or the online Nikon D70 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Nikon D5100 or the Nikon D70 – 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 D5100:

• More detail: Offers more megapixels (16.1 vs 6MP) with a 64% higher linear resolution.
• Better image quality: Scores substantially higher (30 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (3.1 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (3.3 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.2 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.51x vs 0.50x).
• 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 (921k vs 130k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (128x97mm vs 140x111mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 119g or 18 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (660 versus 400) on a single battery charge.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.0).
• More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
• More modern: Reflects 7 years and 2 months of technical progress since the D70 launch.

Advantages of the Nikon D70:

• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More heavily discounted: Has been around for much longer (launched in January 2004).

If the count of individual advantages (bullet points above) is taken as a guide, the D5100 is the clear winner of the match-up (19 : 2 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 D5100 and the Nikon D70 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 D5100 or the D70 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why expert reviews 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
