It's got a DOF scale that shows F/4. Does that mean anything?
I ask3ed myself that same question, so I looked at a couple of lenses,
their DOF marks all start at f4. It won't be slower than f/4.
A guy on Pentax forums has found a clever way to figure out how big it is.
He figures:
Changing the zoom on my monitor, to get the mount the same size as a
physical K mount...
90mm from the lens base (not including the mount) to the top of the hood.
75mm at the widest part of the barrel, where the hood starts.
72mm at the focus ring.
68mm at the 'aperture ring'.
I also concur with the earlier measurement of 67mm for the filter size.
