Lowerpro flipside 200.

In it goes my:
K200d Pentax dSLR
50mm f/1.7 Pentax F-series
24-60 f/2.8 Sigma EX-DG series
70-300mm f/4-5.6 macro Tamron
And eventually:
Pentax 50-135mm f/2.8
I also have 2 filters and my transfer cord in it. I hope that the tripod I ordered will fit as well. If not it has a loop to hold the tripod.
The lowerpro zipper is against your back so its impossible to get robbed without knowing it.
