Canon 350D vs 850D

The Canon EOS 350D (called Canon XT in some regions) and the Canon EOS 850D (labelled Canon T8i in some countries) are two digital cameras that were revealed to the public, respectively, in February 2005 and February 2020. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 350D has a resolution of 8 megapixels, whereas the 850D provides 24 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 350D and the Canon EOS 850D? 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 side-by-side display below illustrates the physical size and weight of the Canon 350D and the Canon 850D. 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.

The 350D can be obtained in two different colors (black, silver), while the 850D is only available in black.

Compare 350D versus 850D top
Comparison 350D or 850D rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 850D is notably larger (13 percent) than the Canon 350D. However, the 850D is markedly lighter (5 percent) than the 350D. In this context, it is worth noting that neither the 350D nor the 850D 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 350D gets 400 shots out of its NB-2LH battery, while the 850D can take 800 images on a single charge of its LP-E17 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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 850D was launched at a somewhat lower price (by 17 percent) than the 350D, which makes it more attractive for photographers on a tight budget. 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 sensor inside a digital camera is one of the key determinants 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 850D is 1 percent bigger. 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.

Technology-wise, the 850D uses a more advanced image processing engine (DIGIC 8) than the 350D (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.

Canon 350D and Canon 850D sensor measures

With 24MP, the 850D offers a higher resolution than the 350D (8MP), but the 850D has smaller individual pixels (pixel pitch of 3.72μm versus 6.41μm for the 350D). Yet, the 850D is a much more recent model (by 14 years and 11 months) than the 350D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 850D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 850D 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 Canon 350D are 17.3 x 11.5 inches or 43.9 x 29.3 cm for good quality, 13.8 x 9.2 inches or 35.1 x 23.4 cm for very good quality, and 11.5 x 7.7 inches or 29.3 x 19.5 cm for excellent quality prints.

The 850D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 350D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS 850D are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 350D and the 850D 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 850D has a higher magnification than the one of the 350D (0.51x 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 350D and Canon 850D along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 850D has a touchscreen, while the 350D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The 850D has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 350D does not have a selfie-screen.

The Canon 850D 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 350D writes its imaging data to Compact Flash cards, while the 850D uses SDXC cards.

It is notable that the 850D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 350D does not provide wifi capability.

The 850D is a recent model that features in the current product line-up of Canon. In contrast, the 350D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 350D was succeeded by the Canon 400D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 350D and the Canon 850D? Which camera is better? The listing below highlights the relative strengths of the two models.


Advantages of the Canon EOS 350D:

  • More compact: Is smaller (127x94mm vs 131x103mm) and thus needs less room in the bag.
  • More heavily discounted: Has been available for much longer (launched in February 2005).


Arguments in favor of the Canon EOS 850D:

  • More detail: Has more megapixels (24 vs 8MP), which boosts linear resolution by 74%.
  • Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC II).
  • Broader imaging potential: Can capture not only stills but also 4K/24p video.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.51x vs 0.49x).
  • 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 115k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (7.5 vs 3 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (800 versus 400) out of a single battery charge.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was released into a lower priced segment (17 percent cheaper at launch).
  • More modern: Reflects 14 years and 11 months of technical progress since the 350D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 850D is the clear winner of the contest (17 : 2 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.

350D 02:17 850D

How about other alternatives? Do the specifications of the Canon 350D and the Canon 850D 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 350D or the 850D. 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.

Expert reviews

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], 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
