Canon 5D Mark III versus Nikon D5300

The Canon EOS 5D Mark III and the Nikon D5300 are two digital cameras that were officially introduced, respectively, in March 2012 and October 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (5D Mark III) and an APS-C (D5300) sensor. The Canon has a resolution of 22.1 megapixel, whereas the Nikon provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 5D Mark III vs Nikon D5300

The physical size and weight of the Canon 5D Mark III and the Nikon D5300 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the 5D Mark III – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D5300 is considerably smaller (31 percent) than the Canon 5D Mark III. Moreover, the D5300 is substantially lighter (49 percent) than the 5D Mark III. It is worth mentioning in this context that the 5D Mark III is splash and dust resistant, while the D5300 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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (5D Mark III) and the Nikon Lens Catalog (D5300).

Concerning battery life, the 5D Mark III gets 950 shots out of its LP-E6 battery, while the D5300 can take 600 images on a single charge of its EN-EL14a power pack.

The price is, of course, an important factor in any camera decision. 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 D5300 was launched at a markedly lower price (by 77 percent) than the 5D Mark III, 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: Canon 5D Mark III vs Nikon D5300

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.

Of the two cameras under consideration, the Canon 5D Mark III features a full frame sensor and the Nikon D5300 an APS-C sensor. The sensor area in the D5300 is 58 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 5D Mark III and Nikon D5300 sensor measures

Despite having a smaller sensor, the D5300 offers a slightly higher resolution of 24 megapixel, compared with 22.1 MP of the 5D Mark III. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.91μm versus 6.25μm for the 5D Mark III). However, it should be noted that the D5300 is a somewhat more recent model (by 1 year and 7 months) than the 5D Mark III, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. Coming back to sensor resolution, it should be mentioned that the D5300 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

5D Mark III versus D5300 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the D5300 provides a faster frame rate than the 5D Mark III. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.

 

Feature comparison: Canon 5D Mark III vs Nikon D5300

Apart from body and sensor, cameras can and do differ across a variety of features. The 5D Mark III and the D5300 are similar in the sense that both have an optical viewfinder.

Review summary: Canon 5D Mark III vs Nikon D5300

So how do things add up? Which of the two cameras – the Canon 5D Mark III or the Nikon D5300 – has the upper hand? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Canon EOS 5D Mark III:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (950 versus 600) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More heavily discounted: Has been on the market for longer (launched in March 2012).

ilogo

Arguments in favor of the Nikon D5300:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More dynamic range: Captures a broader range of light and dark details (2.2 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • More compact: Is smaller (125x98mm vs 152x116mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 470g or 49 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 (77 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 7 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the D5300 comes out slightly ahead of the 5D Mark III (9 : 8 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.

5D Mark III 08:09 D5300

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 5D Mark III and the D5300 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. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted 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 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.
