Hello all, I recently purchased an N2020 with an MF-19. The instruction manual included was apparently for use with an N2000/MF-19 combo, not an N2020. There is a button on the MF-19 which is labelled "AF". Obviously, in an N2000, there is no concept of "AF", so it wasn't described. Could someone tell me the function of this button? I have used MF-21's and MF-26's before, and they both provide an AF mode whereby focus priority is forced, even in manual focus mode, but this doesn't appear to be the case in the MF-19. Thanks, Chris Kalisiak [EMAIL PROTECTED]
