got mine, its quite comfy i can get all my gear in bar one lens (150mm macro) but to be fair its not a lens i would take all the time. Its big enough to pack a days worth of lenses which is what i wanted it for. I have had to remove the pouch so i can fit the camera mounted with the 17-70 and the 70-200 length ways. To the sides a flash is easily acommadated along with the 10-22, 50 & 85 lenses.
there is space left over for my cokin p filter system and 10-22mm hood. The side pocket hapily contains spare battery for the camera and 4AA's for the flash, pen, business cards & roughly 8 memory cards (without cases). The other side is reserved for a drinks bottle. i think i will have to get a sliplock pouch on one strap for immediate stuff when on shoots.
I think the biggest downside is the tripod mounting. the bottom bit that you fit in 2 feet could of been a little longer and wider. so the tripos sits lower. My giottos tripod and head when on my back are roughly the same height as the crown of my head which looks daft and also if getting through restricted spaces can get in the way.
all in all a great bag and i dont think its designed to carry all your kit but who needs all their kit all the time!? e.g. My primes are rarely used when going nature trekking as i call it so they stay at home and the macro takes their place. Also when doing portraits and urban scenes the macro stays at home.
With regards to my future planned upgrades which may be a 28mm prime and a 24-70 of some description to replace the 17-70. i think it has scope to accomadate any of my requirements so all in all I am very happy!
