Canon 350D vs RP

The Canon EOS 350D (called Canon XT in some regions) and the Canon EOS RP are two digital cameras that were announced, respectively, in February 2005 and February 2019. The 350D is a DSLR, while the RP is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (350D) and a full frame (RP) sensor. The 350D has a resolution of 8 megapixels, whereas the RP provides 26 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 RP? 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 RP. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. 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 RP 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 Canon RP is notably smaller (5 percent) than the Canon 350D. Moreover, the RP is markedly lighter (10 percent) than the 350D. In this context, it is worth noting that neither the 350D nor the RP 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 350D gets 400 shots out of its Canon NB-2LH battery, while the RP can take 250 images on a single charge of its Canon LP-E17 power pack. The power pack in the RP can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 350D was launched at a markedly lower price (by 31 percent) than the RP, 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 350D features an APS-C sensor and the Canon RP a full frame sensor. The sensor area in the RP 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.

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

With 26MP, the RP offers a higher resolution than the 350D (8MP), but the RP has smaller individual pixels (pixel pitch of 5.76μm versus 6.41μm for the 350D). Yet, the RP is a much more recent model (by 14 years) 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 RP implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RP for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 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 RP 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 RP are ISO 100 to ISO 40000, with the possibility to increase the ISO range to 50-102400.

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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 RP offers substantially better image quality than the 350D (overall score 25 points higher). The advantage is based on 2.5 bits higher color depth, 1.1 EV in additional dynamic range, and 2.2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The RP indeed provides for movie recording, while the 350D does not. The highest resolution format that the RP can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the RP has an electronic viewfinder (2360k dots), while the 350D 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 RP offers a wider field of view (100%) than the one in the 350D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the RP 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 adjacent table lists some of the other core features of the Canon 350D and Canon RP along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 350D has one, while the RP does not. While the built-in flash of the 350D is not very powerful, it can at times be useful as a fill-in light.

The Canon RP 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 RP uses SDXC 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 350D and Canon EOS RP and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RP 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 RP 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 features and operation of the 350D and RP can be found, respectively, in the Canon 350D Manual (free pdf) or the online Canon RP Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 350D or the Canon RP – 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.

Advantages of the Canon EOS 350D:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Longer lasting: Can take more shots (400 versus 250) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in February 2005).

Arguments in favor of the Canon EOS RP:

• More detail: Has more megapixels (26 vs 8MP), which boosts linear resolution by 81%.
• Better image quality: Scores substantially higher (25 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (2.5 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.2 stops ISO advantage).
• 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/30p video.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.49x).

• More modern: Reflects 14 years of technical progress since the 350D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the RP is the clear winner of the contest (23 : 5 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 350D and the Canon RP place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 incomplete and does no justice, for example, to the way the 350D or the RP perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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, please note that some of the review sites have changed their methodology and reporting over time.
