I think this could be one of the 'Click Beetles'. Although I'm not to hot on these down to a species level. Your camera seems to have a good lens with a very short depth of field. Try 'image stacking' to create a really detailed photo. There are a couple of good free programs available for this on the net. It can be tricky at first and a monopod is very helpful in the field but it is really rewarding when you get it right.
