Canon M6 Mark II vs XTi
The Canon EOS M6 Mark II and the Canon EOS Rebel XTi (labelled Canon 400D in some countries) are two digital cameras that were officially introduced, respectively, in August 2019 and August 2006. The M6 Mark II is a mirrorless interchangeable lens camera, while the XTi is a DSLR. Both cameras are equipped with an APS-C sensor. The M6 Mark II has a resolution of 32.3 megapixels, whereas the XTi provides 10.1 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 M6 Mark II and the Canon EOS Rebel XTi? 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.
The physical size and weight of the Canon M6 Mark II and the Canon XTi 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 XTi is notably larger (27 percent) than the Canon M6 Mark II. Moreover, the XTi is substantially heavier (36 percent) than the M6 Mark II. In this context, it is worth noting that neither the M6 Mark II nor the XTi 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the M6 Mark II gets 305 shots out of its LP-E17 battery, while the XTi can take 370 images on a single charge of its NB-2LH power pack. The power pack in the M6 Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will obviously take relative prices into account. 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 XTi was somewhat cheaper (by 6 percent) than the M6 Mark II at launch, but both cameras fall into the same price category. 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.
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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the XTi is 3 percent smaller. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of chip-set technology, the M6 Mark II uses a more advanced image processing engine (DIGIC 8) than the XTi (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.
With 32.3MP, the M6 Mark II offers a higher resolution than the XTi (10.1MP), but the M6 Mark II has smaller individual pixels (pixel pitch of 3.23μm versus 5.71μm for the XTi). However, the M6 Mark II is a much more recent model (by 13 years) than the XTi, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon M6 Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M6 Mark II for good quality output (200 dots per inch) amounts to 34.8 x 23.2 inches or 88.4 x 58.9 cm, for very good quality (250 dpi) 27.8 x 18.6 inches or 70.7 x 47.1 cm, and for excellent quality (300 dpi) 23.2 x 15.5 inches or 58.9 x 39.3 cm. The corresponding values for the Canon XTi are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The M6 Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M6 Mark II has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Canon EOS Rebel XTi are ISO 100 to ISO 1600 (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.
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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The M6 Mark II indeed provides movie recording capabilities, while the XTi does not. The highest resolution format that the M6 Mark II can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the XTi has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M6 Mark II relies on live view and the rear LCD for framing. That said, the M6 Mark II can be equipped with an optional viewfinder – the EVF-DC2.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M6 Mark II has a touchscreen, while the XTi has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The M6 Mark II 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 XTi does not have a selfie-screen.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the M6 Mark II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Canon M6 Mark II 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 M6 Mark II writes its imaging data to SDXC cards, while the XTi uses Compact Flash cards.
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 M6 Mark II and Canon EOS Rebel XTi and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M6 Mark II offers wifi support, while the XTi does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The M6 Mark II is a recent model that features in the current product line-up of Canon. In contrast, the XTi has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the XTi was succeeded by the Canon Xsi. Further information on the features and operation of the M6 Mark II and XTi can be found, respectively, in the Canon M6 Mark II Manual (free pdf) or the online Canon XTi Manual.
So how do things add up? Is the Canon M6 Mark II better than the Canon XTi or vice versa? The listing below highlights the relative strengths of the two models.

- More heavily discounted: Has been around for much longer (launched in August 2006).
If the count of individual advantages (bullet points above) is taken as a guide, the M6 Mark II is the clear winner of the match-up (19 : 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.
How about other alternatives? Do the specifications of the Canon M6 Mark II and the Canon XTi place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the M6 Mark II and the XTi 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.
This is why hands-on reviews by experts are important. 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 ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
