The 70-300L has ring USM, but AFAIK the economy 70-300 just has an otherwise conventional gear train with a US motor. It's a step up from a micromotor but not really different in operation. All lenses I've tested are capable of focussing much finer than you can tell, like better than a few % of the shallowest DOF.I'm still unclear as if either would work better with the live view remote software/for m purposes (past the longer reach of the 300mm obviously).
No, remote control triggers the same internal processes as pressing a button on the camera, so you get what you get just the same.
Thanks, WilbaW. I was steered towards one of your photos for reference on lenses. You do great work. You answered my question well, and I may hail you for more questions soon. I have to go to bed and stop typing but I did have a question for you about one of your photos/lenses. I'll be back soon to ask you about it
Thanks again.
