When I bought my 600mm F4 I needed something practical to carry it around in. Obviously it needs to keep my lens protected, but at the same time not be too heavy in itself
After quite a bit of research and email correspondence with Kinesis they advised me on the equipment I needed. Besides the lens case, I also purchased a harness system to fit to the case so I could carry it, leaving my arms free to carry the tripod or whatever...
[L621] PC Long Lens Case 600
(Now replaced with the L622) $296.00
For 600/4 lens w/ hood extended but w/o body. Will also carry most 500/4s with body attached and with hood extended.
Will carry my Pentax K20D with 600mm F4 attached
The case is strong enough, and tall enough, to use as a temporary seat if needed!
The belt and shoulder harness system has provision for additional pouches etc
(Bit like military 58/soldier 95 pattern webbing setup)
