I just received on:
- Outside fabric thinner than the Flipside 400. The inner shell is very good, the same as the F400, the more it is removable.
- Plated back is better than the F400, at least that's my first impression, It seems less bulky. This is probably due to its shape more "rectangular".
Most important, the Nikon D4S goes gently with a 70-200 F2.8 lens hood MONTE!
The 300 F2.8 will return but removing one of the two rows of side pockets and back lens hood. The Flipside 500 will be more suitable in the latter case !!!
