A lot of photographers think that to make the most of a trip to the mountains they need to take every lens, every filter, every manner of

reflector they own, a lighting kit and a spare camera body, just in case. At the same token, I know of some famous landscape and nature photographers that usually only carry one camera with an 18-200mm lens. That lens will have a
polarizer filter and a U/V filter. Nothing more. In my opinion, a small pack is great for long or treacherous hikes. Before heading out onto such a hike know what you are going to shoot. Research your trail. If there are going to be great landscape views but the trail is exceptionally long and/or treacherous then I would suggest using an 18-200mm lens to shoot both landscapes and wildlife and nothing more. If you are going to pack two lenses then you have three configurations that make sense depending on your priority. If you want to
capture landscapes and wildlife then a fixed focal wide angle lens and a 70-300mm will be your best bets. If landscape and macro is your thing then either a fixed focal wide angle or an 18-120mm zoom would be the perfect choices for landscape. A

50mm, 100mm, or even a 200mm macro will all help you capture amazing macros on your mountain treks. If you are after wildlife and macros then I would suggest a 70-300mm for wildlife and a 50mm for macro. Anything larger for macros will add a considerable amount of weight to your small pack. Since a tripod of any decent size will most likely not be an option on a small pack I would highly recommend either a quality monopod or a small lightweight tripod, like a gorilla pod. Lowepro make some of the best small packs on the market. The Lowepro Cirrus (available
here on Amazon) is a great pack for camera and single lens. For a two lens pack, check out the Lowepro Slingshot 100 All-Weather bag (also
available on Amazon).
