Took delivery of my bag yesterday, spent most of last night playing with it and arranging my kit, everything fitted perfectly and I still have room left, it's exactly what I needed. It's very sturdy and all dividers are customisable and can be removed and placed where I need them. All lenses including my sigma 10-20mm fit in no problem. I even have room for my Panasonic hd camcorder.
The one thing that was worrying me was my cokin filters and lens fitting, however they all fit in too.the only kit I don't have in at the moment is my chargersI but that's not really an issue.
With all my kit in and having my battery grip on the 7100, I still have room for my lastolite 22cm speedlight softbox folded up on top.
Great bag, so glad I went for this one.
