60D owner for 10 years deciding whether to buy R6 mark 2 or R7?

I do a lot of wildlife photography Bears Birds and I'm in the field. I tried the R8 a good camera but battery life small buffer inadequate evf what's the deal breaker. I have a lot of money tied up in Canon lenses so I'm sticking with Canon for me the choice was either R6 Mark II or R7. Only hesitation is the full frame crop factor on my 400 mm lens. can I compensate with an extender? Zoom in photoshop?

If the EF glass was sold off how about this?
R6II
RF 24-240
RF 200-800

I was thinking of that combo too. Just starting over and not having to adapt older lenses. I've found older Micro Motor lenses are not able to keep up. It becomes very apparent on mirrorless cameras.

To me, for shooting bears in the wild, 100-400 is a tad short - even for some birding.  I think the 100-500 at minimum, but as an L lens is likely to be more expensive than the even longer 200-800.  That new lens is very impressive.

I decided that the RF 200-800mm USM lens would be a better choice. Since the RF 24-240mm USM lens was brought up. That lens already covers more than half of the RF 100-400mm lens including more. The R6 Mark II was also the body I was looking at for Full Frame.

Well, looks like WE have come to a common conclusion.  I guess it remains to be seen if our OP agrees! 🙂

I found as time goes on it may be better to sell off older non-L lenses instead of adapting them. Then just starting new if your budget allows you too. If that particular lens or lenses have an equivalent in the RF Mount. I've been shrinking my APS-C lens and older non-L lens collection. I no longer own any APS-C lenses. I still have 2 consumer grade lens that were given to me by a family friend. When I do go to the RF Mount. All of my lenses have an equivalent replacement for them. Even though the focal lengths or apertures may not match exactly. Like for instance the EF 16-35mm F/2.8L III USM lens was replaced by the RF 15-35mm F/2.8L IS USM lens. Even though the new RF Mount version is 1 mm wider and adds IS now. Or for instance the EF 85mm F/1.8 USM lens was replaced by the RF 85mm F/2.0 Macro STM lens. Now not the exact same aperture. But the same focal length, it's a stop slower but it has Macro & IS capabilities. It also has an STM AF motor instead of a Ring Type USM AF motor. I think all newer lenses will go this direction now. Since USM lenses can't provide very quiet AF during video work.

Certainly see your logic.  I still have some DSLRs - three are more memorabilia (although fully functional): the original D30 (2000), D60 (2002), 400D (Rebel Xti to you), and two others - the 80D and 5DsR.  For them I still have the  EF17-40L, EF 24-105L, EF 70-200L f/4 MkII IS USM, 70-300L, 100-400L MkII EF-S 18-135 IS USM. Sigma 150-600c, 60-600s.  No immediate plans to dispose of them, although I just sold $20k worth of other legacy gear.
Present R inventory: R5, 2xR6, R6II, 14-35L, 24-105 f/4L, 24-240, 100-500L

If the R5 was an option in 2019 I would've gone the RF Mount back then. The only R series cameras were the original R, RP & Ra (Astro version of the original R). The battery life wasn't very good. But it has gotten better though. My uncle still owns his EOS 10D from 2003. That was his first digital camera and it predates the EF-S Mount. He still has his EOS 630 from 1987 along with the EF 70-210 F/4 AFD & EF 50mm F/1.8 AFD lenses. He still has first gen EF lenses. Those are 2 out of the 8 available lenses at launch in 1987. My dad still has the EOS 650 the very first EOS film body. Along with the EF 35-70mm F/3.5-4.5 lens. I still can't believe that there were only 8 lenses at the release of the EOS system. L lenses wouldn't appear until later on. The EF 100-300mm F/5.6L was the first L lens for the new EOS system in 1987.

Thanks for the old lens compatibility with mirrorless camera information. I will probably purchase at least one of your recommendations. Dan

If you do plan on using EF lenses use the EF-RF Mount adapter. Stick with the Canon mount adapters. 3rd Party Mount adapters cause all sorts of problems.
