Not me, the OVF is not needed, this is a P&S, not a Dxxx and it has limitations.
I tried the G15 and didn't like the pictures. For me the P7700 makes better images.
The only thing I don't like about th P7700 is that it is slow, 5 seconds to write a NRW to the file. I am using a 45 second SanDisk, going to try a 90 in a while and I hope that speeds it up to a more useable speed, I have my doubts.
I use it as a P&S, if I want better pictures I bring my D3s
