Originally posted by pres589 I don't think there is direct aperture control on the MZ's besides the MZ-S which is its own thing anyway.
There are 3 types of MZ cameras:
1) The MZ-S, which we know about
2) The MZ-3 and MZ-5 style, where they have basically traditional shutter speed and aperture controls like the bayonet cameras introduced in the 70's (and were previously on the screw-mount cameras before that)
3) The MZ-6 and MZ-10 style, where you can set the shutter speed by pushing the switch that is around the shutter button, and you can set the aperture by pushing the Av button while manipulating that same switch. The *ist has similar controls.
So #3 would let you do full manual with these lenses, where #1 lets you control the aperture directly in AV mode, and #2 only allows it to be set by an automatic mode.

And I think some of the MZs also have a different control that is like a wheel, but it doesn't spin, that you use rather than a switch around the shutter.
