I would always go for the primes, but then I always feel the needed light and minimum shutter speeds of medium format gear rather limiting and would take any bit of aperture I can get …The option is to go for the 70 and the new luscious 100 (with only a 2K difference). Any thoughts?
Mat, that is exactly what I would like the AF to behave, but it does not "lock" and stay there but instead is constantly focussing, as in continuous AF until I take my thumb off the button (Please see I have a Leica S2 body, this might behave differently from the later S with the thumb joystick ?).Hi Dirk
That doesn't sound right to me, your camera is acting in a different way to mine or maybe I have mine set up in another way.
I have mine set to manual focus with the rear joystick enabling auto focus, I can then use my thumb to tap the rear joystick, activate auto focus, once it has locked I can release my thumb and the camera doesn't then change that focus point, it is instantly back to manual focus and I can recompose as I like. Focussing with your thumb doesn't activate continuous focussing on my camera.
Does that make sense?

If this behavior is as designed with the S2, I will have to work on my timing or revert to use AF with the shutter release …
I don't see any setting to change the AF behavior when setting up the camera to use the thumb button for AF - do I over look something?
When using the AF bound to the shutter release button and using single AF, it locks on wonderfully and every shot is perfectly in focus.
I have completely stopped using continuous focus with the S2 - it is simply to slow to follow subject (or camera) motion sufficiently.
