It seems that most do not use the OVF on their GRD. Can someone explain why someone would use an OVF on the GRD? I mean, no exposure information is displayed in the OVF, it does not show whether your subject is in focus (I think Snap will work around this) and it does not fully frame the subject image (I realize that one does get used to this). So, why and/or under what circumstances would one use the OVF on a GRD? Is it just a "last resort" to get the shot if lighting conditions are such that you cannot use the LCD? Thanks.
