Well, I'll be glad to offer my two cents on this topic and add Wisner to the lis t. I was in the same situation as you about two years ago. I had a similar pro blem with my old 4x5 and decided that I was going to get a good solid camera tha t had all the funcitons I wanted and that I could still take it out on the trail and it would work with out a problem. After a long search I decided on the Wi sner Technical. A great camera that should serve your needs well. If you are re ally concerned about weight, you might think about their expedition model. And i f you ever have a problem all you need to do is call Wisner and they will make i t right.
