The reason that this is a “mini” review is that I’ve already reviewed its big brother, the Retrospective 10, here.
After traveling with the 10 version, I decided to trade it in for the smaller 5. This trade-in worked well for me. I found the Retrospective 5 to have all of the good features of the 10 (sturdiness, ruggedness, not being a prime target for thieves), while being more compact and easy to travel with. After an 11 day trip to Barcelona (sometimes dubbed the pickpocket capital of the world) and staying right on Las Ramblas (pick pocketing central), I was able to safely transport this bag comfortably with no attention from thieves. The Pinestone color camera bag just looked like a messenger bag, which I carried across my shoulder. In the evenings, this also doubled as a large purse, carrying my iPhone and travel essentials. The shoulder strap was comfortable and I had no issues carrying this for long walks, hikes, and Metro rides. I even hiked up a steep trail in the Pyranees with it on.
This bag would only be useful for you, though, if you were traveling with minimum photographic equipment. I carried my Canon 5D Mkii with one lens on it, with a few small accessories (memory cards, USB cable, battery charger, and lens brush). If you need something to transport more than 2 lenses, I would go with big bro Retrospective 10.
