Body comparison

The physical size and weight of the Canon R7 and the Nikon D40 are illustrated 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.

Size Canon R7 vs Nikon D40
Compare R7 versus D40 top
Comparison R7 or D40 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D40 is somewhat smaller (2 percent) than the Canon R7. Moreover, the D40 is markedly lighter (15 percent) than the R7. It is worth mentioning in this context that the R7 is splash and dust resistant, while the D40 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the R7 gets 660 shots out of its Canon LP-E6NH battery, while the D40 can take 470 images on a single charge of its Nikon EN-EL9 power pack. The power pack in the R7 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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

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 D40 was launched at a markedly lower price (by 67 percent) than the R7, 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. 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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D40 is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (R7) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon R7 and Nikon D40 sensor measures

Despite having a smaller sensor, the Canon R7 offers a higher resolution of 32.3 megapixels, compared with 6 MP of the Nikon D40. 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 3.20μm versus 7.85μm for the D40). However, it should be noted that the R7 is much more recent (by 15 years and 6 months) than the D40, 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 Canon R7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the R7 for good quality output (200 dots per inch) amounts to 34.8 x 23.2 inches or 88.4 x 58.9 cm, for very good quality (250 dpi) 27.8 x 18.6 inches or 70.7 x 47.1 cm, and for excellent quality (300 dpi) 23.2 x 15.5 inches or 58.9 x 39.3 cm. The corresponding values for the Nikon D40 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 R7 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS R7 has a native sensitivity range from ISO 100 to ISO 32000, which can be extended to ISO 100-51200. The corresponding ISO settings for the Nikon D40 are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 200-3200.

In terms of underlying technology, the R7 is build around a CMOS sensor, while the D40 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.

R7 versus D40 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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the R7 has an electronic viewfinder (2360k dots), while the D40 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 R7 offers a wider field of view (100%) than the one in the D40 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the R7 has a higher magnification (0.72x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon R7 and Nikon D40 along with similar information for a selection of comparators.

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

One feature that differentiates the R7 and the D40 is in-body image stabilization (IBIS). The R7 reduces the risk of handshake-induced blur with all attached lenses, while the D40 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The R7 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D40 does not have a selfie-screen.

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 R7 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 Canon R7 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 R7 writes its imaging data to SDXC cards, while the D40 uses SDHC cards. The R7 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D40 only has one slot. The R7 supports UHS-II cards (on both slots), while the D40 cannot take advantage of Ultra High Speed SD cards.

It is notable that the R7 offers wifi support, while the D40 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The R7 is a recent model that features in the current product line-up of Canon. In contrast, the D40 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the D40 was succeeded by the Nikon D40X. Further information on the features and operation of the R7 and D40 can be found, respectively, in the Canon R7 Manual (free pdf) or the online Nikon D40 Manual.

ilogo

Arguments in favor of the Nikon D40:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Less heavy: Has a lower weight (by 90g or 15 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (67 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in November 2006).

If the count of relative strengths (bullet points above) is taken as a measure, the R7 is the clear winner of the match-up (26 : 5 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 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.

R7 26:05 D40

How about other alternatives? Do the specifications of the Canon R7 and the Nikon D40 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the R7 or the D40. 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 where reviews by experts come in. 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 review scores listed above should be treated with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
