I was looking for that rare gem: a bag that protects my camera equipment, which enables fast access and simultaneously capable of carrying the essentials for small walks of a half-day (papers, small first aid kit, raincoat, sweater ...). The Fastpack 200 attracted me. Almost as good as a SlingShot for speed of access, but with the comfort and porting of a true backpack and more (the Slingshot has a shoulder strap, this one has two straps), c is almost the ideal bag for my particular purpose. The quality Lowepro is: impeccable finishes, attention to detail, thoughtful arrangements, the brand reputation is deserved. The lower part, on camera equipment is arrangable measure. Just move the Velcro dividers for precisely match the equipment that is still well ensconced. I ranks without problems my Nikon D90 with its 18-105 mounted with its visor, ready in a jiffy thanks to the quick access, and there is room for two or three other objectives, charger, all cables, plugs, filters, memory cards and even the manual (in the outer pocket). The upper part, you put what you want. The available volume is substantial, of course, less than in a real backpack, but well above other specialty bags picture. (Those who need to carry a laptop and more will turn to the Fastpack 250, the 200 does not permit it.) The ergonomics are perfect. Once we got a little led the movement to rotate the Fastpack to extract the camera without removing the backpack is readily accomplished. I have not had time to wear it for a ride in a consistent length, but it seems to me that the carrying comfort is provided by straps and back stuffed. What to see in use. I also appreciated the details (some even not described yet little stingy on the website of the manufacturer), for example the net bottle, carabiner for keys, MP3 player pocket placed on one of the straps or multiple pockets internal. It's missing the All Weather protection available on other Lowepro bags, to make it the perfect product. Thank you to the many commentators on this site or on others, whose opinions have informed me when making my choice, always difficult operation when it is not possible to test the product in real life.
