Canon T6i vs Epson R-D1

The Canon EOS Rebel T6i (called Canon 750D in some regions) and the Epson R-D1 are two digital cameras that were announced, respectively, in February 2015 and March 2004. The T6i is a DSLR, while the R-D1 is a rangefinder-style mirrorless camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 24 megapixels, whereas the Epson 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 Epson R-D1? 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 T6i and the Epson R-D1 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.

Compare T6i versus R-D1 top
Comparison T6i or R-D1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Epson R-D1 is notably smaller (5 percent) than the Canon T6i. However, the R-D1 is markedly heavier (12 percent) than the T6i. In this context, it is worth noting that neither the T6i nor the R-D1 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (T6i) and the Leica M Lens Catalog (R-D1).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. 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 75 percent) than the R-D1, 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. 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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the R-D1 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 Epson R-D1 sensor measures

Despite having a smaller sensor, the Canon T6i offers a higher resolution of 24 megapixels, compared with 6 MP of the Epson R-D1. 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 R-D1). However, it should be noted that the T6i is much more recent (by 10 years and 10 months) than the R-D1, 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 Epson R-D1 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 Epson R-D1 are ISO 200 to ISO 1600 (no boost).

T6i versus R-D1 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 are not only capable of taking still images, but also of capturing video footage. The T6i indeed provides movie recording capabilities, while the R-D1 does not. The highest resolution format that the T6i can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The T6i and the R-D1 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 adjacent table lists some of the other core features of the Canon T6i and Epson R-D1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The T6i has one, while the R-D1 does not. While the built-in flash of the T6i is not very powerful, it can at times be useful as a fill-in light.

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 R-D1 does not have a selfie-screen.

The T6i writes its imaging data to SDXC cards, while the R-D1 uses SDHC cards. The T6i supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the R-D1 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 Rebel T6i and Epson R-D1 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 R-D1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Epson R-D1 (unlike the T6i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the T6i and the R-D1 have been discontinued, but can regularly be found used on eBay. The T6i was replaced by the Canon T7i, while the R-D1 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 and Epson websites.

Review summary

So what conclusions can be drawn? Is the Canon T6i better than the Epson R-D1 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of 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 2.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 235k 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 shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 1 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 65g or 10 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • 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.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
  • More modern: Reflects 10 years and 10 months of technical progress since the R-D1 launch.

ilogo

Arguments in favor of the Epson R-D1:

  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been around for much longer (launched in March 2004).

If the number of relative strengths (bullet points above) is taken as a guide, the T6i is the clear winner of the match-up (17 : 2 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.

T6i 17:02 R-D1

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the T6i or the R-D1 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 hands-on reviews by experts 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
