Re: The DOF preview can work, too

What I've learned to use is the DOF preview, if you have a decently fast lens mounted. Since the camera runs the lens wide open for exposure and AF, the DOF preview shows the shallowest possible DOF, certainly it does on the EM1.

I don't have an EM1, but this seems wrong to me.   Shouldn't "DOF preview" stop down the lens and increase the DOF so that you can preview what the actual shot is going to look like?
