I've exhausted my search for the perfect bag and have narrowed it down to these two:
Tenba Messenger Daypack
Lowepro Fastpack 350 AW
I have a Canon 5D Mark II with Canon battery grip attached at all times. I also have a 24-105 and a 70-200 f/4 lens and a 580EX II speedlite.
I want to be able to carry around both my 17" MacBook Pro, my iPad, and my camera listed above. My most important feature is that it can be converted into a regular daypack/backpack for non photo use.
I'm leaning towards the Tenba Messenger Daypack, but I've read that it will be a tight fit with the grip attached to the 5D Mark II and lens in the camera insert area, and that it can really make the camera insert bulge out. I also don't like that there's no rain cover. However, I do prefer the ample pockets on the Tenba, and I love that I can convert the Tenba daypack to a regular backpack.
I like the Lowepro Fastpack 350 AW because it will fit all of my camera gear comfortably, has a rain cover and a tripod holder. I'm not sure if it will fit my iPad. I don't like that it has a smaller compartment, has less pockets for storing miscellaneous things. Most importantly, I'm not sure if I can convert this bag to a regular backpack for non photo use.
Given that you know what I want to carry, and understand that I would like to convert the pack for non photo use, which one would you recommend to me? Please vote in the poll and discuss. It would also be extremely helpful if anyone who owns either of these bags provide input on which one you think would work better for me given my situation.
