Deet is nasty stuff - I have finger print on a lens hood thanks to deet.
Definitely - I have a nice deep fingerprint in the shutter release of one of my old Rebel bodies thanks to the stuff. I now use a towel to wipe off my palms after putting it on - seems to work
On the Flipside 500 AW commerical they sho that the bag can hold a Canon EF 500 f4 lens with a reversed lenshood. Then it should be able to take the EF 300 f2.8 II IS USM shouldn''t it
I saw that, too, and it makes me thing it will work. They also have a photo of an older Nikon 300mm f/2.8 lens with the hood attached (in the extended position, I think) and it looks like it just fits, thickness-wise. Then again, length isn't the issue in the Flipside 400 AW, it's the depth of the bag, and the 500 AW is roughly 1.5" deeper. It's supposed to arrive today, and I'm very hopeful it will work.
alek35, the Vertex 300 AW looks like an awesome and huge bag, but like the Gura Gear bags, it has stuff I'll never use (and would rather not pay for) like the removable straps and stuff that are meant for air travel. I usually stuff my pack in a cheap duffel bag (for stealth and to protect the straps) for air travel, or take my LowePro Pro Messenger 200 AW and a lighter kit (16-35. 24-70, and 70-200 with both extenders).
TrabimanUK, the Tamrac Expedition 7x also looks like a great bag, but it looks to be a little smaller that I need, closer to the Flipside 400 AW.
As I said before, it's times like these that make you sad the brick & mortar shops are gone. I held off o the Gura Gear for now - I'll try out the Flipside 500 AW tonight and if it all fits, I'll take it out for a test drive tomorrow.
