A few thoughts:
- Might EOS R2 come out simultaneously with the 5D5?
- Do folks really think Canon will potentially undermine 1DX3 sales with a 12 fps rig at half price (or less)? I recognize they have the stills throughput potential to move 32 x 14 from the M6 Mark II, but that's a massive bump from the original EOS R. Seems a little too good to be true to me.
- IBIS = cool (if true). We all could use it and seemingly everyone (not shooting howitzer superwhites) has been asking for it for some time. That plus solid peaking / manual focus assist will make the 'tinkering with older / weirder lenses' camp very happy.
- Curious how well IBIS would work with existing IS lenses, adapted EF IS lenses, etc. Folks have (to this point) paid extra for lens IS, and if there is a lower price point without IS, the folks who already committed to lens IS may want some performance assurances that the lens IS was not paid for in vain (i.e. that it combines with IBIS to a better effect than if the lens lacked IS).
My humble take on your thoughts:
- Canon might possibly do this if they are truly ready. They have made sure to get the ball rolling with their flagship announcement of the 1DX miii out of the way, and so far, the response from the targeted market has been overwhelmingly positive. Personally, I see them coming through with a blockbuster announcement of both the EOS R ii and the 5Ds mirrorless replacement to keep the momentum going in their favour.
- Personally, I do not think that the announcement of either EOS mirrorless camera will potentially undermine the 1DX iii sales, due in large part to the fact that the professionals that have purchased the earlier versions of the 1DX have been waiting for this, and they will purchase the new version without looking at a mirrorless camera. This will however give the fence-sitters a very good reason to now choose Canon if they were indeed thinking of going to Sony, especially if they were already Canon DSLR users in the past, who wanted to make the jump to mirrorless, myself included.
- IBIS, although not a deal breaker for me, will be an awesome addition.
- I do believe that IBIS, working hand in hand with Canon's already awesome IS glass, will deliver some spectacular results.
