I have a Lowepro Mini Trekker, I think that's the model, for my Pentax 645 kit. Pretty heavy! For 35mm or - gasp! - digital I have the $35 backpack that Amazon sells. What a deal! For walkabout casual use I scored a little Lowepro shoulder bag for only $10 which has enough room for 2 lenses and a flash, plus some film, etc. One thing I would never buy is a bag proclaiming the camera name. Why advertise steal me?
