If you are a photographer and shoot with a medium format digital back(or want to), these guys will become your best friends. I purchased my digital back(a refurbished Phase One P30+) a few years ago from them when I lived in NYC. Since then I’ve dealt with them numerous times and they’ve always been around for technical questions by phone and drop-ins. Thank heavens they opened an L.A. location and just in time because I was having a gradient issue with my processed files. Right away Ken was able to diagnose the problem, an issue that even Phase One HQ was not able to figure out. Go see them. They are just a nice group of people who know their stuff when it comes to medium format digital.
