Canon XTi vs Pentax K-1
The Canon EOS Rebel XTi (called Canon 400D in some regions) and the Pentax K-1 are two digital cameras that were announced, respectively, in August 2006 and February 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (XTi) and a full frame (K-1) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Pentax provides 36.2 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 XTi and the Pentax K-1? 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 side-by-side display below illustrates the physical size and weight of the Canon XTi and the Pentax K-1. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The K-1 can be obtained in two different colors (black, silver), while the XTi is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-1 is notably larger (41 percent) than the Canon XTi. Moreover, the K-1 is substantially heavier (82 percent) than the XTi. It is noteworthy in this context that the K-1 is splash and dust-proof, while the XTi 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. 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 XTi gets 370 shots out of its NB-2LH battery, while the K-1 can take 760 images on a single charge of its D-LI90 power pack.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

The price is, of course, an important factor in any camera decision. 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 launched at a markedly lower price (by 56 percent) than the K-1, 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.
The size of the sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon XTi features an APS-C sensor and the Pentax K-1 a full frame sensor. The sensor area in the K-1 is 162 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 36.2MP, the K-1 offers a higher resolution than the XTi (10.1MP), but the K-1 has smaller individual pixels (pixel pitch of 4.88μm versus 5.71μm for the XTi). Yet, the K-1 is a much more recent model (by 9 years and 5 months) than the XTi, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the K-1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Pentax K-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 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.
Unlike the XTi, the K-1 has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Canon EOS Rebel XTi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Pentax K-1 are ISO 100 to ISO 204800 (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.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 K-1 offers substantially better image quality than the XTi (overall score 34 points higher). The advantage is based on 3.3 bits higher color depth, 3.6 EV in additional dynamic range, and 2.3 stops in additional low light sensitivity. 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 are not only capable of taking still images, but also of capturing video footage. The K-1 indeed provides for movie recording, while the XTi does not. The highest resolution format that the K-1 can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. The XTi and the K-1 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 K-1 offers a wider field of view (100%) than the one in the XTi (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the K-1 has a higher magnification (0.70x vs 0.49x), 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 XTi and Pentax K-1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The XTi has one, while the K-1 does not. While the built-in flash of the XTi is not very powerful, it can at times be useful as a fill-in light.
The Pentax K-1 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 XTi writes its imaging data to Compact Flash cards, while the K-1 uses SDXC cards. The K-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the XTi only has one slot.
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 XTi and Pentax K-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the XTi does not provide wifi capability.
Studio photographers will appreciate that the Pentax K-1 (unlike the XTi) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Travel and landscape photographers will find it useful that the K-1 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the XTi and the K-1 have been discontinued, but can regularly be found used on ebay. The XTi was replaced by the Canon Xsi, while the K-1 was followed by the Pentax K-1 II. Further information on the features and operation of the XTi and K-1 can be found, respectively, in the Canon XTi Manual (free pdf) or the online Pentax K-1 Manual.
So how do things add up? Is there a clear favorite between the Canon XTi and the Pentax K-1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS Rebel XTi:

If the count of relative strengths (bullet points above) is taken as a measure, the K-1 is the clear winner of the contest (25 : 6 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 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 XTi and the Pentax K-1 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the XTi or the K-1. 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.
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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 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 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.
