I recently got a Fuji GS645s, I went through all the options and though the mamiya 6/7 have a lot going for them I wanted as little weight as possible. The Fuji is light and from the results I have got the lens appears to be very sharp. You dont need an internal meter and as others have noted it will give you a lot more options the Mamiya press cameras go for good prices and a good meter can be had fairly cheaply. There are an awful lot of options open to you with a separate meter, the whole world of older folders for example. That being said the non ttl meter of the Fuji is accurate, as long as the meter is reading from the area being photographed it should do the job just as well, my mother shot loads of Kodachrome 25 with a camera that had a selenium meter on top, the slides are perfectly exposed, as good as the ones I shot using a Canon AE1p with TTL.
