When I asked for camera bag recommendations over at dpreview.com I was first recommended the DH 50 V2.0 holster type bag from Think Tank.

Next next suggested bag was the Sling-O-Matic 20 - also from Think Tank.

The third recommendation I got was for the Tamrac 5788 Evolution 8.

While the Sling-O-Matic is a sling bag that can also work as a backpack the Tamrac is the other way around - it's a backpack with side access which means it can be used as a sling bag.

It doesn't look like it will hold my 70-200mm with the hood attached, so I wouldn't be able to use it as a sling bag, but it looks like a very rugged bag that I would feel comfortable keeping my gear in.

I've added the Tamrac to a page with the other camera bag recommendations

When I started looking for a camera bag for my still not delivered Canon 5D Mark III I didn't think of looking at holster bags - I simply thought they were too small to hold anything of the length I was looking for.

But it turns out that I was wrong, and there are indeed holster - or top loaders - that will fit a good sized DSLR with a 70-200mm zoom and the hood attached (extended)

I posted in the dpreview.com forum for suggestions to a bag and one user came back with a recommendation for a specific Think Tank bag - the DH 50 V2.0.

Unlike most other camera bag descriptions Think Tank didn't just provide the internal and external dimensions, but they mentioned specific lenses that would fit in the bag, on a Pro-size DSLR and with the hood extended.

Lowepro seems to make a similar bag - the Toploader Pro 75 AW - but I can't find any description or review that tells me exactly what I can expect to fit in the bag.
