This bag is very convenient to use, but is only suitable for an SLR equipped with a single goal. This can be large with an adjustable depth (even if the zipper device does not seem very safe). The triangular shape of the bag with her tight base saves a little space but prevents to put the bag on that basis alone to avoid dropping. I would have liked a more broad and solid basis. The bill appears to me of good quality, strong material and hood deployable very useful. Finally, the storage of different small parts is easy, which is very useful. Despite some reservations, I like this bag, even if my device is not very big there floats a little.
