Shutter Speed on 645N

In aperture priority mode I took a shot at 1/750th. There is no click on the shutter dial to get this speed? Is there any way to manually achieve the 1/750th? What other speeds can you get using aperture priority aside from 750? I have only run a couple of rolls of film through my camera and just noticed this on the imprinted data.

Thanks

The shutter is stepless, so in Av mode it will select 1/750s if it's trying to expose between 1/500 and 1/1000 (although it will likely round up or down in the VF).

I'm afraid there's no way of keying in that shutter speed manually, though.

I could be wrong but, I think the 645N will use half stop shutter speeds in P or Av mode. 645NII will do third stops I think.
I'm pretty sure you can only use full stops in M mode.
