Canon 1D Mark IV vs 77D

The Canon EOS-1D Mark IV and the Canon EOS 77D are two digital cameras that were officially introduced, respectively, in October 2009 and February 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark IV) and an APS-C (77D) sensor. The 1D Mark IV has a resolution of 16 megapixels, whereas the 77D provides 24 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 77D? 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.

Body comparison

The physical size and weight of the Canon 1D Mark IV and the Canon 77D 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 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 77D is considerably smaller (47 percent) than the Canon 1D Mark IV. Moreover, the 77D is substantially lighter (56 percent) than the 1D Mark IV. It is worth mentioning in this context that the 1D Mark IV is splash and dust resistant, while the 77D 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 (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 (77D). 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 77D can take 600 images on a single charge of its LP-E17 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 77D, there are third party battery grips available as optional accessories (see here on eBay).

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 77D was launched at a markedly lower price (by 82 percent) than the 1D Mark IV, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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 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 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 77D an APS-C sensor. The sensor area in the 77D 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.

Technology-wise, the 77D uses a more advanced image processing engine (DIGIC 7) than the 1D Mark IV (DIGIC IV), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the 77D offers a higher resolution of 24 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 3.72μm versus 5.70μm for the 1D Mark IV). However, it should be noted that the 77D is much more recent (by 7 years and 3 months) than the 1D Mark IV, 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 77D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 77D for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 77D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

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 77D are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the 77D has a markedly higher DXO score than the 1D Mark IV (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 1.3 EV in additional dynamic range, and 0.4 stops of reduced low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 77D provides a faster frame rate than the 1D Mark IV. It can shoot movie footage at 1080/60p, while the 1D Mark IV is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 1D Mark IV and the 77D 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 viewfinder in the 1D Mark IV offers a wider field of view (100%) than the one in the 77D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1D Mark IV has a higher magnification (0.58x vs 0.51x), 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 77D along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 77D has a touchscreen, while the 1D Mark IV has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon 77D 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 1D Mark IV writes its imaging data to Compact Flash or SDHC cards, while the 77D uses SDXC cards. The 1D Mark IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the 77D only has one slot. The 77D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1D Mark IV cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 77D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 77D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1D Mark IV does not provide wifi capability.

Studio photographers will appreciate that the Canon 1D Mark IV (unlike the 77D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The 77D is a recent model that features in the current product line-up of Canon. In contrast, the 1D Mark IV has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the 1D Mark IV from Canon. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 1D Mark IV or the Canon 77D – has the upper hand? Is one clearly better than the other? 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 low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
• More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.58x vs 0.51x).
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (10 vs 6 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 600) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.

• More affordable: Was introduced into a lower priced category (82 percent cheaper at launch).
• More modern: Reflects 7 years and 3 months of technical progress since the 1D Mark IV launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 77D is the clear winner of the contest (20 : 11 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.

How about other alternatives? Do the specifications of the Canon 1D Mark IV and the Canon 77D 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 1D Mark IV and the 77D 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.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
