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,

No manual will be accurate until Canon confirm the content and thus performance of the firmware, which, as far as I understand was still not in its final production phase at time of the release announcement.  Nothing official will be published by Canon until that, at least is sorted.

Trevor, while I respect your thoughts and feedback on the firmware this is speculation. The fact is both the HTML and PDF versions have been published by a division of Canon, I would venture to say that is official. It would be difficult to believe that this would be done without the content being accurate and final.

I have blacked out the URL based on Stephen's feedback on site policy.

The main thing is that it comes from an official Canon site and is still there.  If it has been posted and withdrawn that would be a different issue - it would suggest that someone jumped the gun and Canon don't want the info in the public arena because either they are not sure of some technical issue, or it has not been signed off by an authority - and there is history of that pre-emptively happening before to several camera vendors.

It's a moving feast and I would not be surprised if they had hopes of having that firmware for the release a week ago when it drew comment from some reviewers - let's face it, they want to get that stuff on the market as soon as possible, so these things can move very rapidly. 

That's not problem from my perspective, and it falls in line with my assertion that Canon would release official documentation about their products when they are confident of their firmware.

Both versions, html and PDF continue to be available.

Marc, that's great. 🙂

I had a look and have found a link to the 5DII Advanced User Guide, which looks like we got it overnight here. At the moment I can see it only as an HTML and not a PDF. Nevertheless, I shall study it with interest.

I hope you learn what you need to make your decision.

I do know the price here - it's $7,300!🙄

I had the opportunity to use both the R1 and the R5 this past Saturday for an extended time at a local retailer. He also had the 200-800mm that I tried to talk him out of but failed.

After some time with the R5 MII in hand I believe overall it may be a decent upgrade but I'm not sure I can justify the upgrade from my current R5, it provides me with everything I need at the moment. The larger question for me, does it offer enough value to cost almost $1200 more then the current R5?

After my experience with the pre-order on the 200-800mm and enjoying the R5 I'm going to follow the wisdom of a smart gentlemen I know....

a) I am still deciding if the technical innovations that are on offer are seriously going to improve my performance in the types of photography I do, and thus have value to me.
b) I never pre-order anything, and that has shown to be a wise move, given the challenges and frustrations of those who have waited a long time for their pre-ordered RF lenses (I might add this is also true for Fuji and Nikon, but on-one seems to make such a fuss about that, likely because Canon is the bigger player).
c) I prefer to let the dust settle and so will the prices

Just to confirm, Marc - no disrespect was ever intended towards you.  My previous post was in the context of your interchange with Moderator Stephen, particularly his comment "While they may be searchable by Google, they are not listed on the Canon USA site or the cam.start.canon site. You have to have a direct link, which makes them unofficial. "  And you response about it having been posted and thus official.  In which case I was simply stating what I understand is normal Release Management practise for documentation - I made no judgement against your efforts. 😬
I am hoping a PDF version comes out very soon (by the time I finishing typing this, just to confound me, it probably will) as I like to keep a copy on my devices for easy reference.

[Tronhard]

Ha! 😁

Yep, since I own an R5, 2xR6 and 1xR6II, I can hardly justify that kind of investment.  I don't do event photography, like weddings, so I don't need (although LIKE) the ability to select specific subjects as priorities for focus and tracking.  Likely, a lot of these features will, in their own good time, trickle down to the R6 series, and by then I might be interested.
I have to replace a pair of hearing aids and they will cost me $6k.  Life gets in the way of photography: it's tragic...  😕

Absolutely none taken Trevor, people can disagree, have a different perspective or position on a given topic without malice for another person. While I respect Stephen I disagree with his position on this topic, there have been other topics where he and I align perfectly. He always steps forward to assist people with unique challenges when it comes to repairs. He brings a lot of value to the Canon consumer.

The art of meaningful conversation has to some regard been lost. It is not an all or nothing proposition! You can disagree on perspective/position in a conversation as long as it remains ethical/moral and continue to respect that person while maintaining them as a friend. The banter, well it's a little like playing chess.  😉

Interestingly enough, my search did take me to the cam.start.canon site, but the link worked very briefly and then died.  Thereafter non activity.  So, I guess we are in waiting mode.
All the GAS sufferers will be beside themselves (no company included).
