Canon 1D Mark IV vs Sony NEX-6

The Canon EOS-1D Mark IV and the Sony Alpha NEX-6 are two digital cameras that were officially introduced, respectively, in October 2009 and September 2012. The 1D Mark IV is a DSLR, while the NEX-6 is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (1D Mark IV) and an APS-C (NEX-6) sensor. Both cameras offer a resolution of 16 megapixels.

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 Sony Alpha NEX-6? 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

An illustration of the physical size and weight of the Canon 1D Mark IV and the Sony NEX-6 is provided 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 Sony NEX-6 is considerably smaller (67 percent) than the Canon 1D Mark IV. Moreover, the NEX-6 is substantially lighter (72 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 NEX-6 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 (1D Mark IV) and the Sony E-Mount Lens Catalog (NEX-6). Mirrorless cameras, such as the NEX-6, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the 1D Mark IV gets 1500 shots out of its Canon LP-E4 battery, while the NEX-6 can take 360 images on a single charge of its Sony NP-FW50 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.

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.

Any camera decision will obviously take relative prices into account. 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 NEX-6 was launched at a markedly lower price (by 80 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 imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 1D Mark IV features an APS-H sensor and the Sony NEX-6 an APS-C sensor. The sensor area in the NEX-6 is 30 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Even though the 1D Mark IV has a larger sensor, both cameras offer the same resolution of 16 megapixels. This implies that the 1D Mark IV has a lower pixel density and larger individual pixels (with a pixel pitch of 5.70μm versus 4.78μm for the NEX-6), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the NEX-6 is much more recent (by 2 years and 10 months) than the 1D Mark IV, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

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 Sony Alpha NEX-6 are ISO 100 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 NEX-6 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 0.9 bits higher color depth, 1.1 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 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 NEX-6 provides a faster frame rate than the 1D Mark IV. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the NEX-6 has an electronic viewfinder (2359k dots), while the 1D Mark IV has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the NEX-6 has a higher magnification than the one of the 1D Mark IV (0.73x 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 Sony NEX-6 along with similar information for a selection of comparators.

One feature that is present on the 1D Mark IV, but is missing on the NEX-6 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.

The 1D Mark IV writes its imaging data to Compact Flash or SDHC cards, while the NEX-6 uses SDXC or Memory Stick PRO Duo cards. The 1D Mark IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the NEX-6 only has one slot. The NEX-6 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 Sony Alpha NEX-6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 1D Mark IV has a microphone port, which is missing on the NEX-6. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Studio photographers will appreciate that the Canon 1D Mark IV (unlike the NEX-6) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1D Mark IV and the NEX-6 have been discontinued, but can regularly be found used on ebay. The NEX-6 was replaced by the Sony A6000, while the 1D Mark IV does not have a direct successor. Further information on the features and operation of the 1D Mark IV and NEX-6 can be found, respectively, in the Canon 1D Mark IV Manual (free pdf) or the online Sony NEX-6 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 1D Mark IV or the Sony NEX-6 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS-1D Mark IV:

• Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (1500 versus 360) 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 heavily discounted: Has been available for much longer (launched in October 2009).

Arguments in favor of the Sony Alpha NEX-6:

• Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.58x).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More compact: Is smaller (120x67mm vs 156x157mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 885g or 72 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (80 percent cheaper at launch).
• More modern: Reflects 2 years and 10 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 NEX-6 emerges as the winner of the match-up (14 : 11 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. 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 Sony NEX-6 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1D Mark IV or the NEX-6. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
