Some thoughts on the Slingshot 200 AW vs. the Primus AW. For me, the Slingshot is my primary street photography bag while I use the Primus for trips to the Shenandoah National Park. The Slingshot is designed like an urban backpack, slung across one shoulder. It blends in; short of seeing a camera in your hand or knowing the brandname Lowepro, few will guess it contains anything but a couple books and some clothes. For the reason mentioned above related to the strap crossing the chest, I would not carry the Slingshot during a workout. The bag also does not sufficiently stabilize a load for anything but walking. The Primus, on the other hand, is designed like a hiking pack. I realize that the small opening on the side may make it difficult to retrieve a camera but the designers had to consider that the bag opening had to be small enough to prevent your camera from accidentally falling out when you first open the flap. I carry a 20d with a battery grip and a 70-200mm lens and, with a little practice, can get the camera out without a problem. My advice to anyone with the Primus is to practice following a classic rule of martial arts: slow is smooth, smooth is fast. Practicing retrieving the camera at 1/3 speed, then slowly work your way up, replacing the camera the same way each time. Psychology of learning tells us that after 5,000 iterations, the motion will become innate muscle memory. Please also keep in mind when critiquing this pack that prior to this design, we'd have to completely take off our packs to get to our cameras, which meant we either carried the camera non-stop or constantly missed shots. I'm sure Lowepro will make a bigger Primus in time to accommodate those larger lenses that nature photographers love, but I'm very satisfied using the Primus for my outdoor photography.
