What do you use to carry your equipment when you're out and about? Does it depend on the terrain, time of year, phase of the moon etc. For myself, I usually use 3 different bags and vary the combination depending on the terrain or which camera I'm using. If I'm going scrambling somewhere, over rough ground, I'll take my Nikon F80 in an old small(ish) CCS bag. I'll use this with an equally old pair of Lowepro lens cases strapped to my rucksack waistbelt. If the walk is of a more sedate nature, I'll use my Karrimor Pro am (don't laugh) gadget bag. I get a surprisingly large amount of gear inside. The F5 or the C330 end up in this, again with the Lowepro cases for lenses/lightmeter etc. Very rarely, I'll use a Lowepro Nature trekker sack, but it's too big and heavy in its own right to be used for anything other than very short trips. Frustratingly, and I reckon I won't be alone here, I've never been able to find that one bag/sack that's perfect for every occasion. How about you?
