Body comparison

The physical size and weight of the Canon SX510 and the Nikon D70s 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 width, height and depth dimensions are rounded to the nearest millimeter.

Size Canon SX510 vs Nikon D70s
Compare SX510 versus D70s top
Comparison SX510 or D70s rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D70s is considerably larger (113 percent) than the Canon SX510. In this context, it is worth noting that neither the SX510 nor the D70s are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX510 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 SX510 gets 250 shots out of its Canon NB-6LH battery, while the D70s can take 500 images on a single charge of its Nikon EN-EL3a 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The SX510 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 size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 Canon SX510 features a 1/2.3-inch sensor and the Nikon D70s an APS-C sensor. The sensor area in the D70s is 1221 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the SX510 has a native 4:3 aspect ratio, while the one in the D70s offers a 3:2 aspect.

Canon SX510 and Nikon D70s sensor measures

Despite having a smaller sensor, the Canon SX510 offers a higher resolution of 15.9 megapixels, compared with 6 MP of the Nikon 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 1.33μm versus 7.85μm for the D70s). However, it should be noted that the SX510 is much more recent (by 8 years and 4 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. Coming back to sensor resolution, it should be mentioned that the SX510 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX510 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX510 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 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 Canon PowerShot SX510 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Nikon D70s are ISO 200 to ISO 1600 (no boost).

In terms of underlying technology, the SX510 is build around a CMOS sensor, while the D70s 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.

SX510 versus D70s MP

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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D70s has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX510 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon SX510, the Nikon D70s, and comparable cameras.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon SX510 and the Nikon D70s? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Canon PowerShot SX510 HS:

  • More detail: Offers more megapixels (15.9 vs 6MP) with a 59% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Broader imaging potential: Can record not only still images but also 1080/24p movies.
  • 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 (461k vs 130k dots).
  • Faster burst: Shoots at higher frequency (3.8 vs 3 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with a built-in lens, while the D70s requires a separate lens.
  • More compact: Is smaller (104x70mm vs 140x111mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the D70s).
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 8 years and 4 months of technical progress since the D70s launch.

ilogo

Arguments in favor of the Nikon D70s:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/1600s) to freeze action.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (500 versus 250) out of a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been around for much longer (launched in April 2005).

If the count of individual advantages (bullet points above) is taken as a guide, the SX510 emerges as the winner of the contest (13 : 11 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

SX510 13:11 D70s

How about other alternatives? Do the specifications of the Canon SX510 and the Nikon D70s place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR Camera listings 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 says little about, for example, the shooting experience and imaging performance of the SX510 and the D70s in practical situations. 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
