Got an interesting website,
Freestyle Photographic Supplies .Love those 645's.Got an ETRSi,Bronica.Looking hard at the Pentax 645AF or the Mamiya 645AFD.Suppose it will come down to lense prices.Shot a karate school with Kodak 400VC.92 people in the group photo,20x30 enlargement made and no hint of grain.The Bronica was hard to focus in the low light so an AF camera is next.
