I don't see why anyone wouldn't just buy the HD 55-300 instead. Its

The new lens, with its silent focusing and diaphragm operation, is
apparently aimed at people who shoot video.
Then they missed the mark. Video shooters want not just silent
operation, but step-less aperture adjustments as well. The current
camera bodies don't support this and I don't see how they can, the
control wheels are obviously digital jog switches. To get step less
control would probably require an analog wheel control.
Stepless aperture operation is pretty easy to implement via auto
aperture operation.
And it is implemented, from what I understand.
Yep. "Rounding out the key specs and changes is an electromagnetic
diaphragm control system, which, according to Ricoh, will provide
smoother aperture control during video recording."
It's also really easy to implement via control wheel. We've had, for
years, the ability to fine tune the control wheels from half stops to
third stops. There is no reason why a further fine tuning can't be
implemented providing the resolution of the aperture adjustment is
accurate enough. I don't think the mechanical coupling is really
accurate at finer than 1/3 stops, but a micromoter driven aperture
should be able to be accurate to a tenth of a stop or finer.
So, putting into the set up menu the option of finer resolution on the
aperture dial would be a fairly easy thing.
I think at that point, one would want the option closer to the surface,
perhaps built into the new command wheel (which is an effing marvelous
idea).
