Summary: I purchased this case for my Fuji digital camera, which is about 4 x 2.5 x 1.75. Going by the measurements listed in the description, I thought this would fit. Beware! Those must be outside measurements. The inside capacity is much smaller. I then went to the manufacturer's website and they say 5 x 2.75 x 1.5. The case itself is very nice, well-made and would have worked very well if it had been the size I thought it was.
Summary: I bought this for a Sony HX-20V and it fits perfectly. The pouch has a very secure velcro and popper fastener on the back to attach it to a belt or similar (I slip mine around the shoulder straps of my rucksack which keeps the camera handy). The main area is accessed via a zipper section. The camera is fairly easy to access from this but I would say that some care has to be taken to avoid the camera falling out as the opening is big when the zips are undone.
Summary: great long strap - brought to protect my little girls first proper camera. I have to say the whole thing is very strong and the long strap means she can wear it round her neck and there is no chance of loosing the case. The camera sits inside a zip close opening and is protected on all sides - I would recommend this case as a great way to protect a digital camera.
