When weight and space is at a premium, I make sure all my lenses accept the same size filters (e.g.: 24/2 and 50/1.4 both take 52mm filters). Then, I take a Nikon A2 (roughly an 81B, only pinker, like a Tiffen 812) and a polarizer. That's it. If I could take one more filter, it'd probably be a +2 diopter. As far as mixed lighting goes, when in doubt I err on the side of warmth.(posted 8837 days ago)
