hi, i recently bought an olympus epl2 a few months ago and have been taking nice pictures, but i have 2 major problems. i cant figure out how to take sport picture or stop motion pictures. its always blurry even if i take a picture of a finger wiggling slowly. i tried the scene mode that has the action picture and low light etc, it doesn't work, or is a tripod a must? i am really a noob at this lol. and how do i take continuous burst shooting and merge the image together. thank you.
