Good product, several storage pockets (2 front for accessories such as a flat at the back, for storing documents (manual, book ...). You can easily store there his DSLR with attached lens, in my case, a Nikon D5000 with a 18-105 and store an additional objective. For the third objective, it may be very very fair. For a walk on a fine day and have another objective on itself, it is the ideal. However, there is no zipper at the large pocket where put the device (it is against closable by a buckle on the front, so for a slightly sportier ride, a rainy day an unhindered ride, I would recommend another type of bag.
