Canon 1D Mark II N vs T6s

The Canon EOS-1D Mark II N and the Canon EOS Rebel T6s (labelled Canon 760D in some countries) are two digital cameras that were revealed to the public, respectively, in August 2005 and February 2015. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark II N) and an APS-C (T6s) sensor. The 1D Mark II N has a resolution of 8.2 megapixels, whereas the T6s 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 II N and the Canon EOS Rebel T6s? 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 II N and the Canon T6s 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 measures 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 T6s is considerably smaller (46 percent) than the Canon 1D Mark II N. Moreover, the T6s is substantially lighter (64 percent) than the 1D Mark II N. It is worth mentioning in this context that the 1D Mark II N is splash and dust resistant, while the T6s 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 II N) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (T6s). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 1D Mark II N gets 1200 shots out of its NP-E3 battery, while the T6s can take 440 images on a single charge of its LP-E17 power pack. As can be seen in the images above, the 1D Mark II N 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 T6s, Canon provides the BG-E18 vertical grip as an optional accessory (see here on eBay).

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 T6s was launched at a markedly lower price (by 84 percent) than the 1D Mark II N, 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. 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1D Mark II N features an APS-H sensor and the Canon T6s an APS-C sensor. The sensor area in the T6s is 39 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 T6s uses a more advanced image processing engine (DIGIC 6) than the 1D Mark II N (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the T6s offers a higher resolution of 24 megapixels, compared with 8.2 MP of the 1D Mark II N. 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 8.17μm for the 1D Mark II N). However, it should be noted that the T6s is much more recent (by 9 years and 5 months) than the 1D Mark II N, 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 T6s implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T6s for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Canon 1D Mark II N are 17.5 x 11.7 inch or 44.5 x 29.7 cm for good quality, 14 x 9.3 inch or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inch or 29.7 x 19.8 cm for excellent quality prints.

The T6s has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS-1D Mark II N has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Canon EOS Rebel T6s are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 T6s has a markedly higher DXO score than the 1D Mark II N (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.3 bits higher color depth, 0.8 EV in additional dynamic range, and 0.1 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 can also record movies. The T6s indeed provides for movie recording, while the 1D Mark II N does not. The highest resolution format that the T6s can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 1D Mark II N and the T6s 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 II N offers a wider field of view (100%) than the one in the T6s (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1D Mark II N has a higher magnification (0.55x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 1D Mark II N, the Canon T6s, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T6s has a touchscreen, while the 1D Mark II N has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The 1D Mark II N writes its imaging data to Compact Flash or SD cards, while the T6s uses SDXC cards. The 1D Mark II N features dual card slots, which can be very useful in case a memory card fails. In contrast, the T6s only has one slot. The T6s supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1D Mark II N 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 II N and Canon EOS Rebel T6s and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T6s offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1D Mark II N does not offer wifi capability.

Studio photographers will appreciate that the Canon 1D Mark II N (unlike the T6s) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1D Mark II N and the T6s have been discontinued, but can regularly be found used on eBay. The 1D Mark II N was replaced by the Canon 1D Mark III, while the T6s was followed by the Canon 77D. 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 conclusions can be drawn? Which of the two cameras – the Canon 1D Mark II N or the Canon T6s – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the number of relative strengths (bullet points above) is taken as a guide, the T6s is the clear winner of the contest (20 : 10 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 II N and the Canon T6s 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 says little about, for example, the shooting experience and imaging performance of the 1D Mark II N and the T6s in practical situations. 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.

Expert reviews

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.

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. Also, please note that some of the review sites have changed their methodology and reporting over time.
