Difference between old and new R5 for wildlife and using an adapter

[Far-Out-Dude]

My questions are these, how much more and why would the R5 Mark ii work better for wildlife photography than the original version?

Second question, I can manage to get the R5 Mark ii but would not be able to afford an RF lens for now,  I am looking to get the Canon 2972C002 lens adapter so I can use the EF lenses I have (Mainly the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens will be used for wildlife and moons shots) Are there any problems I need to know of when using this adapter? I already use one to use my EF lenses on my Canon M50 that is an EF-M mount but everything is different so I thought I should ask.

Looking forward to the difference in image quality,

I did not, but I thank you for trying.

"I would be curious to see if the ability to prioritize a series of individuals, which is touted for human social events, such as weddings, would be made to work to isolate, say, a predatory animal group or individual hunting in a herd situation such as a pride of lions or even an orca pod.  That would be interesting..."

This is a huge question I have as well, I photograph wild turkey quite a bit and sometimes there is that one Tom that really stands out even if there are others and it would be nice to be able to lock onto him. My M50 has had a lot of problems holding focus on eyes and I end up with shots that are clearly hitting the body mass instead of the face. I think I have what I am about to say right, my have the wrong model number but I think either the R6 or R8 had a tracking feature that helped quite a bit with that but the R5 did not have it or perhaps it was in a download you could do later with the R5?

I wish there was a camera shop in my area, nothing like that for hours though. I will check out your other linked articles shortly, thank you.

The M-series is a long way behind the R-series MICLs in terms of sensor technology, but especially in focus and tracking.  I still retain 2xM5's and 3 EF-M lenses but really for wildlife I would never use the M-series now.

The R5 has an excellent focus and tracking capability, but it should have the latest firmware loaded - there have been multiple updates and improvements since it came out.  It shared that focus/tracking system and improvements with the original R6.  The R6II has the newest sensor and focus/tracking technology and it quite simply epic in its performance.

"firmware" That word simply would not come to my brain so I worded it the way I did hoping you would know what I meant. My friend keeps telling me the 50's are the youth of old age but man I am not sure I can deal with more memory loss. lol Right now the M50 is all I have. I got this image this Spring with it.

I feel your pain! 🙂

FWIW, there are two broad different kinds of components: Hardware - anything you can touch, and Software - which is basically some kind of code.   
Within the Software there are three different types:
Firmware allows different hardware devices to work with each other and control the behaviour of the devices.  Operating systems administer the computer and form an interface between humans and the firmware - they don't create documents of any kind, but they manage things like the desktop and the file management system and web browsers which acts as an extension to the Internet - think of them like the government.
Applications are specialized in creating different forms of data - so Office, Adobe, and Skype are examples.   I hope that helps a bit!

So, in terms of camera functions, firmware will control things that control devices like sensors, exposure, memory, buffering and interface with cards, in cameras they may deliver updates to the user interface, such as additions and changes to the menus, or control of buttons and dials. 
They have a huge impact on the hardware side of the camera's operation, and can be updated to fix bugs in their own programs, and has the potential to improve the capability of hardware through re-jigging of how hardware is used or interacts within the camera.  Such examples in the R5 include managing heating issues, improvements to focusing and additions to the focusing menu options.

A good example of this is Voyager One, the deep space probe that has left the solar system, which then had a memory loss and was sending garbage on system status and reports to Earth.  It took engineers some time to figure out the issue and isolate to a specific bank of memory on the main computer.  As the probe could receive instructions OK, they reprogrammed the firmware to redirect it to use other memory addresses and transmitted that to the computer, triggering the update. The firmware update worked, resolving the issue.  Communications were re-established and normal activity was restored - all billions of km away.

Thank you very much for all the help.

Always welcome! 😊
