Comments about Think Tank Think Tank Multimedia Wired Up 10, Medium Beltpack for a Multimedia DSLR System:

Its a good bag with a lot of options making it a shoulder bag or a waist bag. The waist bag option has some of the features of the speed belt where you can attach more to it. The bag will fit a 5d2 with a 24-105 attached with another lens or 2 plus a flash. Many pockets and little extras along with the great build you would expect from TT.

What I do not like
1. The included dividers that the camera sit in are very flimsy, I contacted thinktank and they are sending me some other options.

2. When using it as a shoulder bag the D rings are a close to your body so if you do not have the bag zipped you may drop your gear.

I did not like the speed series because those bags are hard and clumsy, this one is much softer and easier to carry.

The only bag I would honestly say I like more is the Urban Disguise 35.

Hope this helps, I had a hard time finding reviews of this bag but I was lucky enough to try one out in a store before ordering one from Adorama.
