Slingshot 200.
My Lowepro Slingshot 200 AW with my home made insert. I found the Velcro inserts provided did not suit my needs. My fault. Not Lowepro's. So I used a campers' sleeping pad made of closed cell foam ($10 - $15 Can). It is about 1/4" thick, 20" wide x 6' long and cuts easily with a scissors or Exacto knife. It is tough and lint and crumble free and offers excellent protection against bumps. One pad will suffice for many projects.
e.g. One small 3"x 6" piece and 5 minutes work gives me a platform to keep my batteries from rolling around when being tested. It tales tiny button cells and AAA up to D cells.
The camera in the photo is a Canon T90 for which this insert was not designed. It was made for my Pentax K100d
Empty Slingshot and easily removed insert. Camera manual in a Zip Lock bag always ready beneath the insert.
All equipment is still accessible with the bag half open.
The ugly but useful insert. Long rectangle on left is for Tamron Adaptall 80 to 210mm lens. A strip of foam across the front of it keeps the lens from sliding out. The strip is secured on the side by a small piece of Velcro. Lens on right is SMC Pentax 12 to 24mm DA. An extremely wide brute when with its lens hood. Centre section will take the Pentax K100D with any of the three lenses mounted. The triangular flap in front of the W/A lens compartment keeps the camera securely in its place. The open rectangular cut at the bottom front is for a mesh pocket in the Slingshot. I now always put the lens cap in it so I don't lose them any more.
