O.K. In my experience, expensive stuff isn't necessary, and sometimes is a hindrance/danger.
The Pelican or hard-side cases are wonderful, but scream CAMERA STUFF! STEAL ME! As do the embroidered neck straps, camera bags, etc. Cases and bags tend to be awkward, clumsy, and obtrusive.
Everybody on the face of the earth knows what a camera bag/backpack looks like. Protection is necessary for our equipment, but there are many products that are low-key.
When I was a reporter for a daily newspaper, I carried my camera and lenses in a bright yellow plastic Forest Service garbage bag. Not elegant, but I could leave it in the car, windows down, or unlocked, and nobody stole it.
Disinformation! :D
I have carried several Domke and Tamrac bags, which are good for traveling, but find that a fishing vest my wife gave me years ago does just fine. It will carry extra memory, a pencil or pen, a couple of lenses, 2 water bottles, protein bars,sun block, some filters, a flash, light modifier, spare camera and flash bateries, as well as a shower cap (keeps the camera and lens dry in the wet, and a poncho for me.
Having said that, the vests that photo persons love to wear, you know, the ones with "War Correspondent" embroidered in 6 inch letters, look cool, but, in my experience, the lower pockets, the only ones with size enough to carry large tele zooms, are too low. They are forever getting caught between my body and whatever guardrail, pit wall, fence I am leaning over, to get just the right angle. Not good for expensive optics, or the vest. The top pockets are't big enough to hold my flash and light modifier . My fishing vest's lower pockets are higher and big enough for lenses,and the top pockets are large, removing the problem .
I'll never get rid of my vest, because my kids and grandkids gave it to me, but I'll keep using my old fisherman's vest.
Distraction: One pro I heard of carried his camera an lenses in a gas mask bag. If you are a family person, think diaper bag...Kermit the frog or cuddly bunnies on it. :rolleyes: Who would be dumb enough to steal one of those? Just don't get it confused up with the real deal! If you only have a digital P&S, a shirt with big pockets, like the neat fishing shirts you can get at Cabela's will do just fine. I have one. Less is better.
what I am taking so long to say is that cases and padded bags are fine for getting the equipment there, but when shooting ..take only what your experience tells you is absoluteluy necessary, and never look back. Perform, evaluate, modify, reapeat.
Oh, yeah; learn to clean your camera. It's not hard. A camel hair brush and blower plus a microfiber cloth or three, and lens cleaning fluid aree all you need.
