Canon 1D Mark IV vs 7D
The Canon EOS-1D Mark IV and the Canon EOS 7D are two digital cameras that were officially introduced, respectively, in October 2009 and September 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark IV) and an APS-C (7D) sensor. The 1D Mark IV has a resolution of 16 megapixels, whereas the 7D provides 17.9 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-1D Mark IV and the Canon EOS 7D? 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.
An illustration of the physical size and weight of the Canon 1D Mark IV and the Canon 7D 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 width, height and depth 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 Canon 7D is considerably smaller (33 percent) than the Canon 1D Mark IV. Moreover, the 7D is markedly lighter (30 percent) than the 1D Mark IV. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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 (as in the 1D Mark IV) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (7D). You can compare the optics available in the Canon EF Lens Catalog.
Concerning battery life, the 1D Mark IV gets 1500 shots out of its LP-E4 battery, while the 7D can take 800 images on a single charge of its LP-E6 power pack. As can be seen in the images above, the 1D Mark IV has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the 7D, Canon provides the BG-E7 vertical grip as an optional accessory (see here on eBay).

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 7D was launched at a markedly lower price (by 66 percent) than the 1D Mark IV, 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.
The size of the sensor inside a digital camera is one of the key determinants 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 1D Mark IV features an APS-H sensor and the Canon 7D an APS-C sensor. The sensor area in the 7D is 36 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the 7D offers a higher resolution of 17.9 megapixels, compared with 16 MP of the 1D Mark IV. 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 4.31μm versus 5.70μm for the 1D Mark IV). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
The resolution advantage of the Canon 7D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 7D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon 1D Mark IV are 24.5 x 16.3 inches or 62.2 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.7 x 33.2 cm for very good quality, and 16.3 x 10.9 inches or 41.5 x 27.6 cm for excellent quality prints.
The Canon EOS-1D Mark IV has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon EOS 7D are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.
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 review, the 1D Mark IV has a notably higher overall DXO score than the 7D (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.3 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/30p).
Beyond body and sensor, cameras can and do differ across a range of features. The 1D Mark IV and the 7D 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the 7D has a higher magnification than the one of the 1D Mark IV (0.63x vs 0.58x), 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 1D Mark IV and Canon 7D along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 7D has one, while the 1D Mark IV does not. While the built-in flash of the 7D is not very powerful, it can at times be useful as a fill-in light.
The 1D Mark IV writes its imaging data to Compact Flash or SDHC cards, while the 7D uses Compact Flash cards. The 1D Mark IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the 7D only has one slot.
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-1D Mark IV and Canon EOS 7D 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.
Both the 1D Mark IV and the 7D have been discontinued, but can regularly be found used on eBay. The 7D was replaced by the Canon 7D Mark II, while the 1D Mark IV does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is the Canon 1D Mark IV better than the Canon 7D or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Canon EOS-1D Mark IV:
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
- Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Can take more shots (1500 versus 800) on a single battery charge.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
Advantages of the Canon EOS 7D:
- More detail: Has more megapixels (17.9 vs 16MP), which boosts linear resolution by 6%.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.63x vs 0.58x).
- More compact: Is smaller (148x111mm vs 156x157mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 370g or 30 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 (66 percent cheaper at launch).
If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (6 points each). 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon 1D Mark IV and the Canon 7D 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1D Mark IV or the 7D. 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.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, please note that some of the review sites have changed their methodology and reporting over time.
