Thanks for your reply, I appreciate it! I currently have the 28-70 f/2 (I almost never used the widest end of my EF 24-70, so I knew I wouldn't miss it) and am interested in getting the 70-200 for that extra reach. I'm also considering getting the 24-105 for a lighter travel option as well as more video-based work, although so far I've not found the weight of the 28-70 to be too much of an issue (it makes up for it's bulk by allowing me to leave other lenses at home).Yes, I had the EF-70-200 Mark II. The size is the major difference to me. I am yet to pixel peek with the RF lens yet but the pixel peepers say it is at least as good or even better than the EF version. The past week I focused more on the auto-focus system, while it is good, it is not as fast as the RF 24-70. The price is another factor, but for me, I just prefer not to use an adapter. The only EF lenses I kept are the TS-E-24 and 100 Macro and that is because there are no RF versions yet.
And I'm in the same boat as you with the 100mm macro. I can't wait for an RF equivalent to come out.
