I store all my photo gear in what I believe is the perfect camera bag - but it is huge and weighs 50 lbs fully loaded. I definitely won't be carrying that with me wherever I go. I use the LowePro CompuTrekker AW Plus. Its huge.
When I first started shooting, I carried a camera with me at all times. Recently I've decided to continue doing that. My major problem - my camera is expensive and bulky. I don't want people to rip it off, and it is a PITA to carry around. Sure, the D300 is durable enough to handle everyday use - but it is righteously large.
My solution:
Its more like a man-purse *ahem* satchel than a messenger bag, but it is just large enough to hold the basics
- D300 w/ grip and 50mm f/.8
- Leatherman tool
- Spare headphones (I hate the apple headphones, but they work in a pinch)
- Glasses case
- Toothbrush
- Bandana and Scarf
- Extra 3" knife
- Lighter
Also, just in case I leave it somewhere, there is no doubt about who it belongs to
Of course, it holds an iPad perfectly in the back pocket so if I need to show off my portfolios, I can!
I think of this as my "oh sh*t" bag - I've always got it with me and I can live out of it for a few days if necessary - All I really need is a camera and a toothbrush. As soon as my new Lexar cards get here, I will relegate 8gb of old cards to this bag - I'll have 12gb in the bag at all times.
