I love the Voigtlander 75mm VF on my DP3M. It not only works, it looks great! Brightlines mark the full image area, with dotted lines to compensate for parallax if you are rather close. I don't even look down at the lcd screen any more, except to check my aperture setting, and make sure I haven't inadvertently registered an exposure compensation (the one thing I don't like about the DP2M and DP3M). Those little left-and-right buttons, around the "OK" center-circle spot, will engage exposure compensation, often without your realizing you've hit them. I know that my autofocus spot is in the center of the field, so when looking through the VF, I usually feel confident about what the camera is focusing on, and look out of the corner of my eye to the right for the green autofocus confirmation. I"m typically doing landscape, and am usually looking for an infinity focus anyway, so my focus point isn't as critical as it would be in many other applications. You can forget about any manual focusing using the VF. There is no connection with anything going on inside the camera. It just gives you the framelines for your shot. Have fun choosing. --Barbara
