The best camera is the one you have availabe at moments notice

The camera you use the most is the one you have with you. But let's not kid ourselves - cell phone cameras still leave a lot to be desired - I still prefer the ergonomics and image control of a stand alone camera. Why would I want to use an inferior cell phone camera when I have superior dedicated one?

I've been always carrying camera in a camera bag with its lenses and accessories when I am on the move. That made camera less accessible for spontaneous shots.

I never liked camera straps as I felt they left cameras exposed and more vulnerable to damage by dangling next to the body. I always preferred to have a hand strap (the one I've owne was with Canon 1DS Mk3). However, with a camera "in hand" you don't have a free hand when needed. So I would carry a small bag to place the camera into when not shooting. This strategy works relatively well but prevents grab shots as it takes about 30 seconds to get the camera out of the bag and shooting. 

To have camera accessible at moments notice it either needs to be in your hand or within a grabbing distance. I've done some research on YouTube and Reddit and decided to try a Blackrapid strap system. There are 3 parts to the system - strap itself, FastenR5 attachment point that screws into your cameras tripod mount socket and ConectR swivel carabine. Swivel carbine slides up and down the webbing material strap so you can quickly get camera up to your eye level to grab the shot. 

I've picked up a used strap with a storage pocket on top of it - that sounded like a good idea, but by placing a spare battery in a top pocket it made the strap unbalanced and it kept shifting forward/back around my shoulder and made it less than ideal for carbine to slide up unhindered. At the end I placed nothing in the "pocket" area to maximize padding comfort. Also I shortened the strap to have camera hang above the hips to prevent the camera banging into the side of my leg. The camera did not interfere with my LL Bean Traveler fanny pack that I wear as well for carrying my phone and wallet. 

I am also going to try the Blackrapid strap with a stabilizing strap running under the armpit to prevent sliding. Whichever strap works better that's the one I am going to keep. I am also curious about Spider holsters - I've seen photogs use them more than once. I might try them as well in the future as I do like hanging things around my waist.
