Canon T6i vs Nikon D100

The Canon EOS Rebel T6i (called Canon 750D in some regions) and the Nikon D100 are two digital cameras that were officially introduced, respectively, in February 2015 and February 2002. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 24 megapixels, whereas the Nikon provides 6 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 Rebel T6i and the Nikon D100? 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 T6i and the Nikon D100 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 size dimensions are rounded to the nearest millimeter.

Size Canon T6i vs Nikon D100
Compare T6i versus D100 top
Comparison T6i or D100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D100 is notably larger (25 percent) than the Canon T6i. Moreover, the D100 is substantially heavier (41 percent) than the T6i. In this context, it is worth noting that neither the T6i nor the D100 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 (T6i) and the Nikon Lens Catalog (D100).

Concerning battery life, the T6i gets 440 shots out of its LP-E17 battery, while the D100 can take 370 images on a single charge of its EN-EL3 power pack.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T6i was launched at a markedly lower price (by 63 percent) than the D100, 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. 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 associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D100 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T6i) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon T6i and Nikon D100 sensor measures

Despite having a smaller sensor, the Canon T6i offers a higher resolution of 24 megapixels, compared with 6 MP of the Nikon D100. 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 7.85μm for the D100). However, it should be noted that the T6i is much more recent (by 12 years and 11 months) than the D100, 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 T6i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T6i 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 Nikon D100 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.

The T6i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS Rebel T6i has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Nikon D100 are ISO 200 to ISO 800, with the possibility to increase the ISO range to 200-1600.

T6i versus D100 MP

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").

Many modern cameras cannot only take still pictures, but also record videos. The T6i indeed provides movie recording capabilities, while the D100 does not. The highest resolution format that the T6i can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The T6i and the D100 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 (95%), but the viewfinder of the D100 has a higher magnification than the one of the T6i (0.53x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon T6i and Nikon D100 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T6i has a touchscreen, while the D100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The T6i has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D100 does not have a selfie-screen.

The T6i writes its imaging data to SDXC cards, while the D100 uses Compact Flash 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 Rebel T6i and Nikon D100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T6i offers wifi support, while the D100 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the T6i and the D100 have been discontinued, but can regularly be found used on eBay. The D100 was replaced by the Nikon D200, while the T6i was followed by the Canon T7i. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.

Review summary

So what is the bottom line? Which of the two cameras – the Canon T6i or the Nikon D100 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Canon EOS Rebel T6i:

  • More detail: Offers more megapixels (24 vs 6MP) with a 100% higher linear resolution.
  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 118k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (132x101mm vs 144x116mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 225g or 29 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (440 versus 370) on a single battery charge.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (63 percent cheaper at launch).
  • More modern: Reflects 12 years and 11 months of technical progress since the D100 launch.

ilogo

Advantages of the Nikon D100:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.51x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • More heavily discounted: Has been around for much longer (launched in February 2002).

If the count of individual advantages (bullet points above) is taken as a guide, the T6i is the clear winner of the match-up (17 : 3 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.

T6i 17:03 D100

How about other alternatives? Do the specifications of the Canon T6i and the Nikon D100 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 incomplete and does no justice, for example, to the way the T6i or the D100 perform in practice. 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 adjacent summary-table relays the overall verdicts of several of the most popular 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.

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

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
