Another thing to consider on Focus Mask, is that it seems to like contrast. Many times in the early morning on early evening, I find that I have slightly over expose the first frame so to allow Focus Mask to really get the best read on the image. After checking, I will then get the exposure where I need it.
However as a Tech Camera user, the LCD image review to me is still the most important. Being able to double tap, and see the image at 100%, then make 4 quick finger movements to the corners for a check of focus made a big difference to me. The P65+ which I was also considering at the time, just does not make this process easy. I found it took much longer to get the image to 100% and then trying to navigate around at 100% took forever. Also I found the image quality at 100% very hard at times to determine critical focus.
