If 2 different motor technologies then why only "focus" on VCM in the lens description.They’re controlling two separate groups, one for the floating group (nano USM) and one for the rear focusing group (VCM).
Canon has been doing that lately with just Nano USM, the lenses featuring Dual Nano USM (e.g., 100-500L, 100-300/2.8) have separate groups each with their own motor.
Next question, why VCM instead of Nano USM for one of the two motors? Canon says it used this design because it works well for both photo and video applications (from PetaPixel). I suspect it’s because a voice coil actuator can deliver more force than NanoUSM at the same speed, and the rear focus group of the RF 35/1.4 is reasonably heavy, but not heavy enough to need ring USM.
Surely it should be RF35 f1.4L VCM USM because if the "Tamron 16-300mm F/3.5-6.3 Di II VC PZD MACRO" is a good name then Canon should jump on the bandwagon

Has Canon ever separated USM types before except for STM and USM (whether ring or nano or dual or VCM)?
