Did some more shooting today in Las Vegas where I was attending the CES. Since I was outside, bright, and I needed to conserve battery (and it was friggin cold), I used the VF-2 on my E-PM2. I then noticed that the controls (4-way), direct 'dialed' like ISO, or drive mode, or exposure/aperture (I shoot in A mostly), were really slow to respond, like the camera was too taxed. I don't remember this before, so I think maybe the VF-2 presence is like a computer driving multiple displays...it uses more CPU power and thus the UI is slower. Am I crazy or did anyone else notice that the settings are harder to set because there is greater button lag with the VF-2 (or VF-3)?
