First thing first, the adapter is bound to eat away at least some of the size/weight advantage you may be getting by switching to lower quality gear. There is also the issue of possible AF performance penalties, and what the AF on the 30 year old lenses is going to be like is anybody's guess.
Second, there are no really compact high quality FF zooms, much less with image stabilization. It's just the way life is. If you want full frame AND zoom with good quality, you have to deal with big lenses. None of the currently available FF standard zooms from Canon have filter threads smaller than 77mm. The old Tamron 28-75 and Canon 24-85 come closest but they have their own sets of shortcomings: neither has IS, the former has a buzzing motor and the later is "only" 3.5-4.5 and mechanically not the best. I'll leave the IQ analysis of these to Klaus - the 24-85 was never tested on FF and the Tamron was found to be not exactly stellar (at 21 MP).
Third, if you're willing to sacrifice image quality to that degree, you should not have gone to FF. In APS-C realm there are many compact AND high quality offerings like the Fuji 18-55/2.8-4.
So if you already have the 24-105 RF, just stick with it. Mucking around with adapters and thrift shop lenses is - at least in my book - not worth the paltry weight savings.
Totally agreed, except for potential AF performance issues. If anything, on R-series bodies AF works perfectly with the Canon adapters, and is faster than on dslrs, with the exception maybe of the 1DX II.
Kind regards, Wim
