Canon XTi vs Nikon Z7
The Canon EOS Rebel XTi (called Canon 400D in some regions) and the Nikon Z7 are two digital cameras that were revealed to the public, respectively, in August 2006 and August 2018. The XTi is a DSLR, while the Z7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (XTi) and a full frame (Z7) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Nikon provides 45.4 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 Nikon Z7? 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 Nikon Z7. 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 Nikon Z7 is notably larger (27 percent) than the Canon XTi. Moreover, the Z7 is markedly heavier (21 percent) than the XTi. It is noteworthy in this context that the Z7 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 Z7 can take 330 images on a single charge of its EN-EL15b power pack. The power pack in the Z7 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. 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 XTi was launched at a markedly lower price (by 76 percent) than the Z7, 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.
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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon XTi features an APS-C sensor and the Nikon Z7 a full frame sensor. The sensor area in the Z7 is 161 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 45.4MP, the Z7 offers a higher resolution than the XTi (10.1MP), but the Z7 has smaller individual pixels (pixel pitch of 4.35μm versus 5.71μm for the XTi). Yet, the Z7 is a much more recent model (by 12 years) 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 Z7 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon Z7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z7 for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inches or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inches or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inches or 69.9 x 46.6 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.
The Z7 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel XTi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon Z7 are ISO 64 to ISO 25600, with the possibility to increase the ISO range to 32-102400.
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the Z7 offers substantially better image quality than the XTi (overall score 37 points higher). The advantage is based on 4.2 bits higher color depth, 3.6 EV in additional dynamic range, and 2 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
|Nikon Z7||Full Frame||45.4||8256||5504||4K/30p||26.3||14.6||2668||99|

Many modern cameras are not only capable of taking still images, but can also record movies. The Z7 indeed provides for movie recording, while the XTi does not. The highest resolution format that the Z7 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Z7 has an electronic viewfinder (3690k dots), while the XTi has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the Z7 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 Z7 has a higher magnification (0.80x vs 0.49x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon XTi and Nikon Z7 along with similar information for a selection of comparators.
|Nikon Z7 II||3690||Y||3.2||2100||tilting||Y||1/8000s||10.0||n||Y|
|Sony A7R II||2400||n||3.0||1229||tilting||n||1/8000s||5.0||n||Y|
One difference between the cameras concerns the presence of an on-board flash. The XTi has one, while the Z7 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 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 Z7 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 Nikon Z7 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 Z7 uses XQD 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 Rebel XTi and Nikon Z7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
|Nikon Z7 II||Y||stereo||mono||Y||Y||micro||3.2||Y||-||Y|
|Sony A7R II||Y||stereo||mono||Y||Y||micro||2.0||Y||Y||-|
It is notable that the Z7 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.
Both the XTi and the Z7 have been discontinued, but can regularly be found used on eBay. The XTi was replaced by the Canon Xsi, while the Z7 was followed by the Nikon Z7 II. 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.
So what is the bottom line? Which of the two cameras – the Canon XTi or the Nikon Z7 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

If the count of relative strengths (bullet points above) is taken as a measure, the Z7 is the clear winner of the contest (27 : 8 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.

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 XTi or the Z7 perform in practice. 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 where reviews by experts come in. 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.

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.
