Strap and either a messenger bag or a more traditional camera bag - I have a nice Tenba I bought years upon years ago that fits up to two Rollei bodies, a half-dozen pro-packs of 120 film, and a Sekonic 408 meter in the main compartment, or one Rollei, a Vivitar grip/bracket and a Vivitar 283, plus the aforementioned meter and film. I dislike the never-ready cases for that reason- they always interfere with your ability to take a picture when the opportunity presents itself. But I have a nice canvas messenger bag that doesn't look like a camera bag or something fancy that might have a laptop or other valuables in it - it's an LL Bean messenger bag in the "sea washed" finish. It's big enough to carry all that stuff plus an iPad or a laptop in a separate padded interior compartment.
