Hello World, I am trying to find a good camera bag that will work well for hiking. I am looking for something that will hold my Nikon D5200 plus 3 lenses not attached to the body, lens cleaning kit things, some batteries, and a charger. I am looking for something where I can access the camera without having to take off the bag itself, and I am looking for something that can hold a small tripod. I bought a sling bag from an obscure chinese company that looked to be able to do all of this. And indeed it can. However, upon recently receiving the bag I found it pretty uncomfortable. When I go hiking (which is when I use my camera the most) I will hike for a minimum of 5 hours. So the camera bag must be comfortable during that entire trip. Does a sling bag exist that is comfortable for that long and also can meet my other requirements? If not, can anyone suggest a backpack that can do all of those things? I do not want something that is huge which is why I was looking at sling bags to begin with. Thank you for any suggestions.
