The listing, TWO DSLR FOLLOW FOCUS!!! has ended.
I've upgraded my rig so I no longer need these baby's.
One of the gears (the larger one) no longer snaps into place but someone with a little more fabricating knowledge than me could figure out a way to make this baby work perfectly again.
The other (smaller) works perfectly.
Both will come with a standard gear ring to place around your current lens and will work with these.
These will fit your typical DSLR 14mm rods.
Hope they find a good home. Good luck!
