A little while back I bought a new camera, a Sony NEX-5 with 18-55mm lens. I don't have a camera bag for it yet and because the existing ones are either too heavy, too expensive or just not what I really want, I've decided to make one myself.
What I need from a camera bag:
-lightweight
-Waterproof
-Padding
-Extra space for batteries and other small accessories
-Extra space for small tripod (Gorilla pod type)
-Attachable to hipbelt or shoulder strap
My current plan:
I'm planning on making a rectangular box out of silnylon with CCF for padding on the inside. The camera will be facing lens down/screen up, so there will be a corner of space next to the lens. Here I can put my spare batteries.
I already have a thin (about 6mm) CCF mat that I don't use. It's probably overkill for what I plan on using it for, but since I already have the stuff, it will do. I can cut out an L-shape and fold that so it covers 5 sides of my box. Do I need to make small cuts in the corners so that it will fold more easily? I can also glue a small piece of CCF as a small "wall" inside the box that will form the accessory compartment.
This CCF box will then be placed inside a silnylon bag with a roll top closure. I may put a piece of CCF inside the roll top closure (maybe 2 small pieces, one on the front and one on the back) that will fold down as a lid to cover the screen once the roll top is closed. For the roll top closure I plan on using 1 cm webbing to stiffen the opening. It will be closed with 2 buckles attached to the side of the bag.
For the attachement to my backpack I'm not sure what I'm going to do yet. I might make something similar to what Lowepro uses on their Apex series (http://www.flickr.com/photos/pigpogm/4017158226/). On the other hand, I may just make 2 loops on the back that will go around my hipbelt.
Right now, I don't know yet what I'll do with my tripod. I may just use a strap of velcro to attach it to the outside.
What do you think of my plan? Any advice or criticism is welcome.
