The EOS M series was Canon’s exclusive offering in the mirrorless camera market for a considerable amount of time. Then, around the end of 2018, it finally released the highly anticipated EOS R line of cameras. These cameras have full-frame sensors, which puts them in direct rivalry with brands such as Sony, Panasonic, and Nikon.
The EOS RP is the most basic model in the R series offered by Canon. Given that it shares a number of characteristics with the EOS M50, the most recent model in the M line, we were keen to discover what other differences there are between the two models aside from the size of the sensors. You may view the results of our research down below!
1. Mount, as well as the adapters
The Canon RP revolves around Canon’s brand-new RF mount at its core. Because of its huge 54mm internal diameter (the same as that of the EF mount) and its short back focus, the lens’s rear element may be brought much closer to the image plane. This combination makes it easier to produce lenses that have high optical quality and performance. [Case in point:]
The EOS EF-M mount is more compact since it was designed to fit the APS-C-sized sensor of the M series of cameras, of which the M50 is a part. It has a diameter of 47 millimeters at the throat.
Dedicated adapters for EF and EF-S lenses can be added to any mount, making it possible to use EF and EF-S lenses interchangeably. This is a very useful feature. However, as the RF mount and the EF-M mount are not cross-compatible with one another, it is not possible to attach an RF lens to an EOS M camera or vice versa.
The two cameras’ sensors are very different sizes, which is one of the most notable distinctions between them.
The sensor found inside the EOS RP has a resolution of 26.2 megapixels and measures 35 millimeters by 24 millimeters (full-frame). This sensor is identical to the one found inside the EOS 6D Mark II, with the exception of modified micro-lenses that are optimized for mirrorless glass.
The Canon EOS M50 utilizes a sensor with a smaller APS-C size and has a slightly lower resolution of 24.1 megapixels, as was noted earlier. The Canon has a crop factor of 1.6x, which is significantly higher than comparable APS-C sensors’ 1.5x crop factor.
C-RAW is Canon’s compressed RAW format, and both of these cameras support it. This format makes the files smaller than the lossless compressed equivalent would have done.
When compared to the EOS RP, the ISO range of the EOS M50 is significantly narrower. Despite the fact that both have a native value of 100, the RP may go all the way up to 40,000 while the M50 has a limit of 25,600 for its maximum value.
Both come with extended value, but the RP gives you more possibilities, giving you the choice between 50, 51,200, and 102,400 according to on your needs. The maximum value that may be added to the M50 is 51,200.
3. Sensor crop in 4K
Both cameras are capable of recording 4K video at either 24 or 25 frames per second. When capturing 4K footage, the EOS RP applies a 1.75x sensor crop and the EOS M50 applies a 1.6x sensor crop. This is in contrast to the 1080p recording mode.
The fact that the two cameras begin with distinct formats also contributes to the significant gap that exists between them in terms of the field of view that they offer. Let’s look at an example using a lens with a focal length of 50 millimeters that was built for full-frame cameras.
On its full-frame sensor, the RP uses a crop factor of 1.75x, which results in an equivalent field of view of around 87.5mm. Due to the smaller APS-C sensor included on the M50, a 50mm lens attached to the camera has an equivalent focal length of 80mm. However, when shooting a 4K video with the M50, an additional 1.6x crop is applied, resulting in an even more restricted field of view (approximately a 128mm equivalent).
Both cameras make use of Canon’s Dual Pixel CMOS AF technology. This means that each megapixel on the surface of the sensor is equipped with two separate photodiodes that are responsible for image plane phase detection.
Autofocus coverage is the same across all models at 88 percent horizontal and 100 percent vertical; but, the RP offers a far larger number of manually chosen AF points (4,799 to be exact). Depending on the lens that is mounted, the M50 gives you access to either 99 or 143 focus points.
In addition to that, the RP provides a greater variety of AF point selection modes. In addition to 1-point AF, Zone AF, and Face+Tracking, it now has the new Spot AF mode, two different options for AF Expansion points, and Eye AF that works with continuous Servo AF and movies as opposed to simply One-Shot AF as it does on the M50. All of these features are a benefit to the camera.
5. Continuous burst shooting and buffer
The M50 has more impressive continuous burst capabilities, hitting 10 frames per second when using One-Shot AF (focus is fixed on the first frame) and 7.4 frames per second when using Servo AF (continuous focusing). In comparison, the RP is only capable of achieving 5 frames per second when using One-Shot AF and just 4 frames per second when using Servo AF. Because of this, the M50 is an improved choice for shooting sports, wildlife photography, and action photography.
The official CIPA specs state that the buffer depth of the M50 is 47 JPGs in a burst at 7.4 frames per second, but the RP can shoot an unlimited number of JPGs or 50 RAW files at a rate of 5 frames per second.
Although the EOS RP is larger and heavier than the EOS M50, the difference is not as significant as you may believe it to be. You may get an idea of how they compare to one another by looking at the following specifications:
- EOS RP: 132.5 × 85.0 × 70.0mm | 440g
- EOS M50: 116.3 x 88.1 x 58.7mm | 387g
The RP has a larger grip, which makes it more comfortable to use when large lenses are attached to the camera. This is the most important improvement.
When viewed from the front, the two look to be rather comparable, with the exception of the M50’s bulging electronic viewfinder (EVF). While the EOS R logo is prominently displayed on the front of the RP, the M50 only displays the word “EOS.”
On the back of the M50, we observe that the LCD screen takes up a larger portion of the available real estate. The RP is the only one of the two that features an AF-On button in addition to the four-way D-pad and the other buttons.
On the top of both models is where you’ll find the hot shoe, the mode dial, the button to capture video, and the shutter button. The M50 only has one control dial, whereas the RP has two, plus the mode dial of the RP comes pre-loaded with three different user-defined settings. In addition, the RP has a dedicated on/off power dial rather than a switch, and it also has a Lock switch next to one of the control dials. Both of these features are standard.
In addition to having connectors for Micro USB and HDMI, the EOS M50 also accepts input from an external microphone. In addition to a microphone and headphone jack, the EOS RP comes equipped with a bigger USB-C port and a tiny HDMI port.
7. Battery type
The EOS M50 utilizes the LP-E12 battery from Canon, which provides around 235 shots on a single charge and 370 shots when set to the Eco shooting mode. Depending on the temperature, the LP-E17 battery that comes with the EOS RP can take anywhere from 240 to 250 pictures on a single charge. Turning on the Eco mode increases this number to 270 pictures.
It is important to note that only the RP can be charged using the USB port, which is a major letdown.
8. Extra features
Both of these cameras provide a Time-Lapse Movie option; however, only the EOS RP has a built-in intervalometer that can store either JPG or RAW files.
In addition, the full-frame model features an Anti-Flicker mode, which helps users to snap photographs in challenging lighting conditions, such as those created by fluorescent lighting.
Those who are interested in a mirrorless camera that has a full-frame sensor will find it difficult to turn down the offer presented by the RP, which has a price tag of about $1300 US. However, despite this, it is still significantly more expensive than the M50, which can be purchased for approximately $630 for the body by itself or for $650 with the 15-45mm kit lens.
In addition to this, there is not yet a reasonably priced kit lens available for the RP at this time. The 24-105mm f/4 is the lens that offers the best value for money for use with the camera; when purchased together, the two lenses will cost approximately $2200.
10. Lens selection
The price has a direct and clear bearing on the ultimate point of differentiation, which is the lens of choice. Although both may be used with Canon’s extensive collection of EF and EF-S lenses by means of an adapter, neither one’s native lens selection is adequate for a variety of reasons. Adapters can be utilized.
As of this writing, there are four lenses available for the R series, and another six are scheduled to be released in 2019. However, the majority of these lenses, including fast zooms and primes, are on the more expensive side, which means that they are not really suited for the RP that is intended for beginners. Why Canon didn’t release a kit lens that was available at a lower price point alongside the launch of the new camera is a mystery.
One of the most pricey lenses available is the Canon RF 50mm f/1.2, which has a maximum aperture of 1.2.
The M50 suffers from the opposite issue that the RP does, namely that there are numerous inexpensive lenses but a limited amount of superior optics. This indicates that in order to achieve the highest potential quality, you will absolutely need to adjust Canon DSLR glass. Additionally, Canon has not invested a significant amount of effort into the production of new EOS M lenses; hence, it is unlikely that the range will expand as rapidly as that of the full-frame series without the cooperation of third-party manufacturers.
As we have discovered during this comparison, there aren’t really too many key distinctions to be made between these two Canon models. In point of fact, I’d go so far as to say that the RP is the full-frame equivalent of the M50.
The sensor size is the most significant difference between the two, so if you want the finest high ISO performance and dynamic range possible, the decision is straightforward.
The M50, on the other hand, has an advantage in terms of its continuous shooting capabilities, which can reach as high as 7.4 frames per second with Servo AF, whilst the full-frame model is only capable of producing 4 frames per second.
There is also the matter of the cost to take into account. In spite of the fact that it is one of the least expensive full-frame models now available, the RP will still require a far larger financial investment on your part than the M50 will, particularly if you intend to purchase native RF lenses to go along with it.
