Body comparison: Canon 30D vs Nikon D850
An illustration of the physical size and weight of the Canon 30D and the Nikon D850 is provided 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 size dimensions are rounded to the nearest millimeter. You can also toggle the display 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 – the 30D – represents the basis or 100 percent 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 D850 is notably larger (19 percent) than the Canon 30D. Moreover, the D850 is markedly heavier (28 percent) than the 30D. It is noteworthy in this context that the D850 is splash and dust-proof, while the 30D 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 (30D) and the Nikon Lens Catalog (D850).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 30D was launched at a markedly lower price (by 58 percent) than the D850, 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 30D vs Nikon D850
The size of the sensor inside a digital camera is one of the key determinants 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 30D features an APS-C sensor and the Nikon D850 a full frame sensor. The sensor area in the D850 is 154 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.
With 45.4MP, the D850 offers a higher resolution than the 30D (8.2MP), but the D850 has smaller individual pixels (pixel pitch of 4.35μm versus 6.42μm for the 30D). Yet, the D850 is a much more recent model (by 11 years and 5 months) than the 30D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the D850 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Canon EOS 30D 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 D850 are ISO 64 to ISO 25600, with the possibility to increase the ISO range to 32-102400..
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 D850 offers substantially better image quality than the 30D (overall score 41 points higher). The advantage is based on 4.9 bits higher color depth, 4 EV in additional dynamic range, and 1.9 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 are not only capable of taking still images, but also of capturing video footage. The D850 indeed provides for movie recording, while the 30D does not. The highest resolution format that the D850 can use is 4K/30p.
Feature comparison: Canon 30D vs Nikon D850
Apart from body and sensor, cameras can and do differ across a range of features. The 30D and the D850 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 table below summarizes some of the other core capabilities of the Canon 30D and Nikon D850 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The 30D has one, while the D850 does not. While the built-in flash of the 30D is not very powerful, it can at times be useful as a fill-in light.
The 30D writes its imaging data to Compact Flash cards, while the D850 uses SDHC or XQD cards. The D850 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 30D only has one slot.
Connectivity comparison: Canon 30D vs Nikon D850
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 30D and Nikon D850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D850 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 30D does not offer wifi capability.
The D850 is a recent model that features in the current product line-up of Nikon. In contrast, the 30D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 30D was succeeded by the Canon 40D.
Review summary: Canon 30D vs Nikon D850
So how do things add up? Is the Canon 30D better than the Nikon D850 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS 30D:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More compact: Is smaller (144x106mm vs 146x124mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 220g or 22 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (58 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in February 2006).
Reasons to prefer the Nikon D850:
- More detail: Has more megapixels (45.4 vs 8.2MP), which boosts linear resolution by 136%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (41 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (4.9 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (4 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.9 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 4K/30p video.
- Larger screen: Has a bigger rear LCD (3.2" vs 2.5") for image review and settings control.

- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (9 vs 5 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (1840 versus 750) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More modern: Reflects 11 years and 5 months of technical progress since the 30D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the D850 is the clear winner of the contest (20 : 6 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 30D and the D850 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.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
