Getting on the trail with a backpack is sometimes painful when you have to stop to open it to get the things you need. So lately i got two Lowepro lens bags #3 and 4 to carry the lens outside the bag and #1 that is tied on the suspender to carry the 200 micro-nikkor lenshood, and on the other suspender a small bag to carry a spare battery, some memory cards, and other small stuff. That way i don't have to open the bag all the time. Next there will be another ballhead mounted on the lowpod so not to transfer the ballhead and the camera from the tripod to the lowpod. That way you spend more time taking pictures.
