Bad experience with HC 50-110 zoom : 4 (yes four !) broken shutter last 2 years with 2 zoom, none could reach 15.000 shoot. Need to buy a third zoom only for spare use when other in overhaul.... work done sometimes under warranty but after 12 month : 1500 € bill each time : expensive game. No serious technical explanation received from Hasselblad. Did someone have the same problems or know about ?
