A:AnswerI believe you do, I’ve never tried to not use one but the pic files are about 40mb in raw format so even if it did have a little internal memory you’d barely be able to shoot anything.
A:AnswerFor video, it can shoot anywhere from 30-60 fps. For still photography, it is 3 fps (as the camera needs time to save the image onto the card). 3 fps is just OK, but for the price it is a good deal.
A:AnswerWell I would love to answer but after a year we still are wishing the camera had a better how to use in English .For 600 dollers it shouldn't be a issue.
