Was skeptical at first because of the material, but I must say the K-51 is "grown fond of" me. The size is sufficient for 1Camera with little accessories. ie mounted at me with EOS 200 Lens, diff. filter and other small parts, Smartphone and a little food for the journey. Ideal for hiking, day trips etc. Should a "Photo safari" plan with tripod, several lenses and whatever we still need, then it is effectively too small. For me, the bag is already several times got wet and the camera etc. was not wet !! - Even though the canvas is not a waterproof material. The front pocket which is closed with a large flap, takes on all sorts of trinkets - inside are 3 compartments that prevent the tumbling of the objects he (can). Laterally is still a net bag and a way to mount a small tripod to hire. Velcro adjustment would have been better. Shoulder belt is well adjusted and also drive the motorcycle has already reinforced. I do not want to give it back and therefore recommended the% star and I have already.
