I sat down and drew up a bean bag design and got a “Prototype” stitched. Here is how it looks as of now.
No fancy material, just out of thin cotton as of now just to get the things right. Final colour would be dull Khaki/ Jungle Green/ Camo and material Nylon/ Canvas/ Rexine and a combo of sorts. Bag was filled with Rice just for this one time 🙂 Eventually will use for poly/ plastic beads as fill in.
On the left is as seen from the outside , Right pic is the top of the bean bag. Lens would be laid from right to left with reference to the top view pic.

The bag would straddle the car window like pic below.

* Broaden the width of the top
* Move the Zipper to the bottom
* Give the top a curvature to cradle the lens along the length
* Engineer a removable strap to hold the lens securely to the bean bag.
Are you planning to sell them ? Will buy few of them 🙂

Thanks for your interest Kalyan.
Will let you know once I have it in final shape 🙂

Filled with Rice instead of beans, just add some Rajma to it. Then in an emergency it would make a great meal!

Rajma works well for lens stability.
If you add a panning plate or some kind of support on the top where one can attach a mounting plate, it will be a great design. Zipper on the bottom is a great move. Filling it with plastic beans will make it lighter, hence less stable. Best will be to fill it with rice/rajma.
Hi Krishnan
Any further thoughts on the bean bag design? Am planning a new one for my Canon 600 mm IS. Could you please offer some advise on the length of the side sections and the width & depth of the top section?
Pl reply to my above mail ID
