I think it's interesting to see what people take with them when they go out. Golf websites have "What's in the bag" posts. Being a tools kind of guy, I like to visit the Cool Tools site that sometimes has posts "What's in the Bag" for all sorts of uses, including photographers and videographers.
So, I thought I'd show "what's in my bag" when I'm out away from my "stuff" or doing street photography. If I'm doing an "on location" shoot there's a lot more stuff "in the bag", but for other/street photography I have to limit myself to what I can comfortably carry. Here's some photos of what I carry:
My camera is a Canon 5D MarkIII. Here's what's on my belt: A Sekonic L-308S light meter that I'll use if I can. Although I try not to use it because its harsh light, sometimes I'll carry a YongNuo YN568EXII at night or for daytime fill flash. Also on my belt is a Samsung Galaxy Pro 8.4 tablet in a pouch I made. In my camera I have an Eye-Fi SD card that sends the photos to the tablet as I shoot. I like this for a better preview of the image than the camera LCD. I know it's a jpg but I still think it helps. I've calibrated it with the X-Rite i1Display Pro just for some better accuracy. Another reason for the tablet is that I can show the person(s) a large image. They love that! However, if I'm doing street photography, I'm very careful about doing that. I'll only do that if I've had an extended conversation with someone and get to know them a bit. It totally depends on my take of that person. Street photography does come with some risks so you have to be very careful.
The lenses I usually carry are a Sigma 50mm f1.4 DG, a Tamaron 85mm f1.8 DI VC USD, and a Canon EF f4.0 70-200mm L IS USM. If I think I'll need more of a wide angle lens I'll carry a Tamaron 24-70mm f2.8 USD Di. One lens will be on the camera and the other two in a ThinkTank Retrospective LC2. In that I'll also carry spare batteries, CD and SD cards. If I think I might be doing some longer exposures I'll carry my Sirui P-326 monopod.
I'd really be interested in what others "have in their bag" when you leave the house or studio, for whatever type of photography you plan on doing.
