Why is autofocus motor in your camera lens important?
- https://www.lensora.com/autofocusmotor.asp
- When you, on a newer camera, press the shutter button halfway to focus, it's a motor in either your camera or lens that ensures that the lens elements move and align themselves to put the object in focus. The autofocus motor is either in the lens or the camera, sometimes in both. However, there are both lenses and cameras without an autofocus motor and would they be …

- The oldest lens drive type is simply a small electric motor. (The oldest autofocus type has its drive outside the lens… but we’ll get to that.) Tiny gears transfer its motion to the lens, and the whole construction is built to fit inside an arched space next to the lenses. That’s why these are called Arc Form Drives. But you’ll more frequently encounter the name Micro motor. …

- It depends on what you're driving. For my camera lens focuser, I used a NEMA 8 PG-19 motor. This is a very small motor with a 19:1 reduction gearbox and it has plenty of torque to turn a lens focus ring using just the 5V supplied by the powered USB hub. For turning larger loads, the same motor can be used by supplying 12V to the Arduino. Tim

- Panasonic's L-mount lenses incorporate both a linear and a stepper motor that work together to give their lenses very fast S-AF speed. Hi there, What I'm interested in particular is lens af technology that facilitates smooth subject acquisition, instead of instantly locking on. I think you should still look at the Panasonic S1 camera because ...
