Read before you buy! Not suitable for digital SLRs,
This review is from: Zing (Uxbk1) Lrg Eveready/Black (Electronics)
If you're reading this, I'm assuming that you're shopping for a case for your *digital* SLR. If so, this case will most likely not be suitable so that's why I've given it one star. However, if you're shopping for a cover for your old manual film cameras like the Nikon FM2 or FE2, it'll fit nicely and for you, I'll give it 3-4 stars.
If you have a digital SLR with a bulky grip, the Zing Eveready will not fit round your body (tested on a Nikon D3100). It comes in two parts like the old leather cases. One half is designed to cover the bottom half of the body and it stays in place while you shoot. The top half goes over the top of the body and the lens. The trouble (apart from being too small to fit round the body) is that even with the body cover on, you will not be able to view the LCD screen on the back and access the buttons. This is because it's for film cameras which don't have LCD screens.
If you're looking for a cover for your digital SLR, look elsewhere. It *may*, however, fit the compact mirrorles ILCs from Lumix and Samsung that have smaller bodies. I haven't tried them so I don't know. If you're still interested in this case, also consider the diameter of your lens. To give you a guidance for size, the box of the Zing Eveready Lrg (Uxbk1) says it'll fit lenses up to 4.5in (11.4cm). Be careful; it also depends on your lens diameter. The width of the case at the lens barrel end was a bit too narrow for my Sigma 18-200mm that's 79mm (diam) x 100mm (length). So if your lens diameter is large, consider getting the large cover rather than the standard cover.
Amazon was unusually poor in not providing any product description so I've included the one from Amazon.com below. Note that it talks about "changing of film".
Product description from Amazon.com:
"Styled after the classic leather camera case but made with the advantages of neoprene, the Universal SLR Camera Case is extremely flexible and fits a wide range of lens lengths and camera bodies. The case bottom attaches to the camera body by running a camera strap (not included) through keeper loops sewn into the case interior. The top fastens to the bottom with dual thumb release clips; swings out of the way quickly for shooting, or it can be removed completely. This system enables quick changing of film and is very easy to use. Velcro tabs allow adjustment to fit different lens/body combinations."
