Hi Dean,
Ended up with the Lowe Pro Lens case for the 200-500. I planned to carry the lens, outside my pack due to size. Sadly the lens is back at Nikon for repairs, due to the rear rubber gasket pulling out. However now I am into a situation with Nikon Repair, west coast, where they are claiming the damage was done via a drop. BS, as it was returned via my local dealer who has verified that the lens was fine. Still not sure where this is going. Lens has been at Nikon since 11/7/15.
I will add, off topic, that from my experiences it seems Nikon has recently taken a real backwards direction on both customer service and repairs period. Hopefully not a trend. If you are not NPS, as I am not, things seem to get shuffled to the back bin.
But at least I have a case for it if I ever get it back.
