Hi guys,
what is the best backpack (best=very ligth, durable and water proof, really good ergonomic with two serious straps) that can carry a 500 f/4, body + grip and TC attached to the lens for 3+ mile hiking. The suitcase that comes with the lens is good for storage but not suable for field carrying.
Thanks
PS. backpack doesn't need to carry anything else, just 500 and body tight and light.
