Body comparison: Canon 30D vs Nikon D70
The side-by-side display below illustrates the physical size and weight of the Canon 30D and the Nikon D70. 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 size dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D70 is somewhat larger (2 percent) than the Canon 30D. However, the D70 is markedly lighter (14 percent) than the 30D. In this context, it is worth noting that neither the 30D nor the D70 are weather-sealed.
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. Yet, since both cameras are based around an APS-C sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (30D) and the Nikon Lens Catalog (D70).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will naturally be influenced heavily by the price. 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 D70 was launched at a markedly lower price (by 29 percent) than the 30D, 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: Canon 30D vs Nikon D70
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. 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D70 is 9 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (30D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Canon 30D offers a higher resolution of 8.2 megapixels, compared with 6 MP of the Nikon D70. 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 6.42μm versus 7.85μm for the D70). However, it should be noted that the 30D is much more recent (by 2 years) than the D70, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
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 D70 are ISO 200 to ISO 1600 (no boost).
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"). Of the two cameras under review, the 30D has a notably higher overall DXO score than the D70 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, 0.5 EV in additional dynamic range, and 0.5 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.

One feature that is present on the 30D, but is missing on the D70 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
Concerning the storage of imaging data, both the 30D and the D70 write their files to Compact Flash cards.
Connectivity comparison: Canon 30D vs Nikon D70

Studio photographers will appreciate that the Canon 30D (unlike the D70) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 30D and the D70 have been discontinued, but can regularly be found used on eBay. The D70 was replaced by the Nikon D70s, while the 30D was followed by the Canon 40D.
Review summary: Canon 30D vs Nikon D70
So how do things add up? Is the Canon 30D better than the Nikon D70 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 30D:
- More detail: Offers more megapixels (8.2 vs 6MP) with a 17% higher linear resolution.
- Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
- Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Larger screen: Has a bigger rear LCD (2.5" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (230k vs 130k dots).
- Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.

- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.0).
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More modern: Reflects 2 years of technical progress since the D70 launch.
Reasons to prefer the Nikon D70:
- Less heavy: Has a lower weight (by 106g or 14 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in January 2004).
If the count of relative strengths (bullet points above) is taken as a measure, the 30D is the clear winner of the match-up (12 : 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 30D or the D70. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
