Some of it is probably due to the lens hood. That 70-300 DO needs the hood in many situations; I mount the lens with the hood in the stored position and then remove or flip the hood into shooting position afterwards but the RF adapter requires more torque than say a traditional EF mount does to mount it making twisting from the hood in-advisable which means I have to lock it from the bottom of the lens; it's more difficult. The 100-400L doesn't need the hood though so it'll be a different experience.

Why does the 100-400 not need a hood? For the record, I use the hood on mine all the time.

The optical function of the hood is to keep errant sunlight from entering the lens on the side, which can cause flares and ghosting. If you aren’t in that kind of a situation, you don’t “need” the hood. 70-300DO is just about the worst lens for flaring due to the DO structure, so I can see how the 100-400L would be relatively in less need of a hood.

Having said that, I make it a habit to use a hood on all my lenses, even ones that deal very well with flares, because a) I’m usually not clairvoyant enough to know my lighting situations a day in advance, and b) they also offer physical protection.
