Believe it or not, I still use a 1970s Zenit B. There are several reasons why I haven't gone digital, but perhaps the most important one is that I walk a lot and I like to take photos when I see them, so the "ever ready" case is ideal. I don't want to carry a camera case on my shoulder, nor do I want to have to retrieve my camera from a rucksack every time I want to take a photo.

Are the any DSLRs which have a case which is as easy to open as the one on my Zenit?

Thanks for any help!
