LukasSchroedernot sure what camera you are using but im gonna guess its the T3i which is very bad in low light conditions. best you can do is have the fastest aperture and play around with the iso and shutter speed. not sure what you mean by RAW cause thats a picture term. if you're going to film with the 8mm you need to get a lot closer. it looks better and the viewer can see what is going on. dont be too worried about skateboards flying at your lense cause the 8mm is such a tank. just make sure to anticipate them.
jmellberg800yeah i have a t3i. would you recommend using a fixed 55mm lens or the kit lens? i have all three of those?
