I just bought two of these, one with each type of lens, for the family to use and share on an upcoming trip. I had been considering just getting the G15 for the trip, but decided this way gives me more options. My kids really like the functionality of the touch screen, since they are used to using an iPod.
Is it true that the M uses a combination of phase and contrast detection, and so if I use my m42 manual lenses on it, will it still give a focus confirmation beep?
And if I use my 50mm 1.8 lens on it, which on my DSLR has inconsistent focus reliability (due I think to having a cheap focus motor which doesn't seem to work too well with phase detection) it will focus much more reliably because the contrast detection on the M will help it?
