the bag be well make and fit my k-x with 18-55mm zoom nicely . inside top flap pocket for extra battery and sd card be nice to have . only problem -- the strap be too short to wear over the opposite shoulder . I be not huge , but when I put the strap over my opposite shoulder the bag come up to my rib . the strap need to be at least 10 '' longer to sit at waist\/hip level . hang the strap over the same shoulder be not nearly as secure . this strap use ` male ' side release connector on each end , most camera bag use clip-type fitting so I have not be able to find a replacement strap .
