Alex, I had extensive discussions during the design phase with the mechanical engineer who designed this adapter. Basically, the gearing provides faster focus, but does not reduce precision.
It really comes down to how much thumb control you have. I find myself using thumb and forefinger; this way you have as much control turning it clockwise as turning it counter-clockwise. It's pretty fast to get accurate focus.
