I have a Pentax DSRL with an 18-250 zoom that takes ~6 fps of 14 Megapixels images and lucky most of the time to catch a photo of my rocket lifting during a launch. Wanted a way to catch good photos each time. I Followed sales for Casio F1-EX on Ebay, these cameras are no longer in production, shoots 60 fps at 6 megapixels, and are used to do golf swing analyst, etc. I was able to purchase one and tries it with my rocket launches... learning curve had me miss completely severaly launches.... I've learned to press button when motor flame starts. Video of photos this weekend. Camera also takes 1,200 fps high speed video too, will try that next.
