I was looking for a high speed camera, but they are all soooo expensive. Read about the Casio - but couldn't find a seller rang Casio UK who told me they pulled out of the UK market??? so bought from Germany, excellent delivery. This has 1000 fps - but I think you would need a MASSIVE amount of light to even stand a chance of seeing anything but a very grainy image. However, I wanted to view industrial machine functions and 120 to 240 fps is just fine - still needs good light though. reviewing and stepping through a video on the camera is very good AND its then got everything else - The only real complaint I have is that there are so many possibilities that I often miss a picture while I'm trying to remember what setting to use !!! Practice and a better memory than mine. In all, very pleased.I have managed to get some really stunning pictures.
