My wife and I are going to Hawaii in the beginning of December. In addition to my Nikon DSLR I would like to take a MF camera primarily for landscape shots. I already own an RB67 but that is too heavy and bulky. I was looking into something like a Pentax 645 with a wide angle lens. Then I came across the Fuji GA645 series. I read a thread on here from last year, and the half a dozen or so people who posted seemed to like this P&S medium format camera. It sounds like it would be perfect for my needs. I'd be interested in reading some thoughts and opinions on the Pentax 645N and/or Fuji GA645 as it relates to being a lightweight, easy to use, MF camera. I see that the Fuji has various models, and I would be interested in recommendations.
