A friend has one and he raved about it. He brought it to a monthly burgers & beer & photo gab fest. It looked good. I bought a different Tenba bag from Robert here at RFF recently. I was impressed by the construction. I made my biannual trip to the local camera store last Saturday. While foraging for chemicals, I spied a pile of these Tenba Messenger bags. They had one in Not black. I am really tired of black bags. Tenba calls it Platinum. I would call it silver/grey. The online prices were in the $115-$125 range. Houston Camera Co-op's price was $99.95. In my hand. No waiting for the mail. Done deal!
I haven't had a chance to use it on a shoot yet. However, I did verify that it will hold enough stuff to keep me busy for a day. It holds my DSLR stuff OR my medium format stuff OR 4x5 film holders & 3 lenses. Plus all the usual odds & ends & bits & pieces. Meters, filters, film, level, stuff, etc. The rangefinder gear fits but is kinda lost. Nice out and about shooting bag for large gear. The camera insert is nice and available seperately. I think I'll buy one for a brifcase I have. Oh, and the padded computer sleeve is very secure and extremely well padded all around. I might be able to stash the RF gear in the computer sleeve. The shoulder strap is first class and comfortable. The zipper in the top flap lets you get at things without opening the flap and making Velcro sounds. Nice. The bag-Wayne interface (back of the bag) is very comfortable as well.
The bag doesn't scream "Camera bag". However, it may scream "Computer inside. Take me." Be careful.
