The rating refers to the fact that is sold this bag as an accessory for the Alpha 77 Sony and their usage as described. You should take both camera + lens and 2 Additional Services Lenses.
My requirements are for an A77 owner actually 0815:
- A77 (with infected lens) - Sony 16-50 - Sony 50F18 Potraitlinse - Tamron 70-300 USD Tele
The bag leaves little latitude adjustment compared to the competition. Lowepro, Kata, Tamrac play here already in a different league even though they are priced hardly differ (with similar models). The problem is less in my case, the value for money but the usability.
Sony A77 with attached telephoto does not fit purely. That is, a lens exchange is necessary to stow the camera or taking pictures with a telephoto. With 16-50 Lens Camera loose between 2 partitions (A Lens Bridge system or the like should be understood). Space for 2 additional lenses provides the pocket but also not more. While I get my little outfit in the bag but only extremely pinched with pressure on the lenses. I then feel that I'm broken by the bag over contactors.
For small system cameras, the case may well suited even if you get better for the same money at Lowepro / Tamrac. For me as A77 Accessories absolutely useless and therefore only one star. For NEX they might be enough, however.
