OK, you will see some reviews about getting the "wrong bag" from Amazon. This is NOT the bag you find on the Pentax site--in fact, I have NO IDEA where it comes from--but i ordered this in preference to the other bag! It has a nice Pentax logo on it, so it is either real Pentax or you should get one before the police catch up with the distributor. The other bag is probably a good choice for those who want to pack MORE gear--but i wanted less. This bag holds my K20D wearing either my 16-45DA or my 55-300DA ED, plus whichever of the two is not on the camera. The camera and lenses are nicely held and protected, and are easily accessed via a single zippered opening that conveniently appears at chest level when you swing the bag around. This will be my travel bag. Mt Pentax DSLR bag holds a lot more, but carrying it all around all day was a tussle in France. The cross-shoulder security and comfort of this bag are both pluses, while the minus is for NO help in configuring the partitions. I had to look at reviews of the Lowe 100 to get any idea of how to do this effectively. I think the two-tone exterior has a funky retro quality that reminds me of the Contaflex era...I like it a lot! Oh, and the top compartment can hold a flash or even a couple more lenses--but for me it will be used for a rain jacket or something else i might need on tour--or just go empty till I buy a sandwich or something. As i said, i was looking for LIGHTWEIGHTGet more detail about Pentax DSLR Crossover Bag.
