The Canon RF lineup is a curious one. The naming convention does not seem to follow delineate a given model into a clearly defined category of camera: entry level, beginner, intermediate, and advanced. For DSLRs, the model numbers those four categories were as follows: xxxxD, xxxD, xxD, and xD. All the full-frame models were in advanced category.
The model numbers in the RF lineup do not follow such clearly defined categories. But, I can say this about them. The feature set of the R50 seems to fall into the beginner category, similar to a DSLR with an xxxD model number, or advanced Rebel in the US with a model name sending with the letter “i”, like T8i. The R50 camera body has a back panel similar to Rebel DSLRs. This screenshot is from the B&H Photo Video web site.
I think you might be disappointed with the feature set in an R50. The R10 could be a better choice for an APS-C entry level camera. Although the R10 also has a “Rebel” back panel. Curiously, so does the R8.
Mainly because of the rear panel layout, I would recommend the R6 or even the R6 mark II. The R6 series also use the same E6 series of batteries as the 6D, although it is recommended that you only use the latest generation of the E6 battery.
As far as low light performance goes, the R10 and R50 may seem to approach the performance to the 6D on paper. But, the metering range suggests otherwise to me. At the time of its release, the 6D was a “low light king” of the hill, and it still is.
So, you might even be happier with the aging 6D Mark II compared to the R50 or even the R10. The 6D2 has an articulating screen, but is also allows for remote shooting using Bluetooth. I use my Wi-Fi only iPad with it and love it. Big screen and no dropped connections because the iPad does not have phone service.
