Canon 40D vs Nikon D610

The Canon EOS 40D and the Nikon D610 are two enthusiast cameras that were announced, respectively, in August 2007 and October 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (40D) and a full frame (D610) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Nikon provides 24.2 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 Canon EOS 40D and the Nikon D610? 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 Canon 40D and the Nikon D610 are illustrated 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.

Size Canon 40D vs Nikon D610
Compare 40D versus D610 top
Comparison 40D or D610 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D610 is somewhat larger (1 percent) than the Canon 40D. Moreover, the D610 is slightly heavier (3 percent) than the 40D. It is noteworthy in this context that the D610 is splash and dust-proof, while the 40D 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (40D) and the Nikon Lens Catalog (D610).

Concerning battery life, the 40D gets 750 shots out of its BP-511A battery, while the D610 can take 900 images on a single charge of its EN-EL15 power pack.

Any camera decision will obviously take relative prices into account. 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 40D was launched at a markedly lower price (by 35 percent) than the D610, which puts it into a different market segment. 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.

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 40D features an APS-C sensor and the Nikon D610 a full frame sensor. The sensor area in the D610 is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon 40D and Nikon D610 sensor measures

With 24.2MP, the D610 offers a higher resolution than the 40D (10.1MP), but the D610 nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 5.73μm for the 40D) due to its larger sensor. Moreover, the D610 is a much more recent model (by 6 years and 1 month) than the 40D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Nikon D610 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D610 for good quality output (200 dots per inch) amounts to 30.1 x 20.1 inches or 76.4 x 51 cm, for very good quality (250 dpi) 24.1 x 16.1 inches or 61.1 x 40.8 cm, and for excellent quality (300 dpi) 20.1 x 13.4 inches or 50.9 x 34 cm. The corresponding values for the Canon 40D are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.

The Canon EOS 40D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Nikon D610 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 50-25600.

40D versus D610 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the D610 offers substantially better image quality than the 40D (overall score 30 points higher). The advantage is based on 3 bits higher color depth, 3.1 EV in additional dynamic range, and 2.1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The D610 indeed provides for movie recording, while the 40D does not. The highest resolution format that the D610 can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 40D and the D610 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 D610 offers a wider field of view (100%) than the one in the 40D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D610 has a higher magnification (0.70x vs 0.59x), 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 Canon 40D and Nikon D610 in connection with corresponding information for a sample of similar cameras.

The Nikon D610 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 40D writes its imaging data to Compact Flash cards, while the D610 uses SDXC cards. The D610 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 40D 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 Canon EOS 40D and Nikon D610 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

The D610 is a recent model that features in the current product line-up of Nikon. In contrast, the 40D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 40D was succeeded by the Canon 50D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon 40D and the Nikon D610? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Canon EOS 40D:

  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • More affordable: Was introduced into a lower priced category (35 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in August 2007).

ilogo

Reasons to prefer the Nikon D610:

  • More detail: Has more megapixels (24.2 vs 10.1MP), which boosts linear resolution by 55%.
  • Better image quality: Scores substantially higher (30 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.1 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.59x).
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (900 versus 750) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Reflects 6 years and 1 month of technical progress since the 40D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D610 is the clear winner of the contest (15 : 3 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 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.

40D 03:15 D610

How about other alternatives? Do the specifications of the Canon 40D and the Nikon D610 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 40D or the D610 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Notes: (+ +) 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 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.
