Awesome, thanks for the replies.

So I guess a good quality variable ND filter is a solid investment? From what I read the cheap ones are not worth your money..

Hi there,

I've been fliming for fun for years on all sorts of consumer grade cameras. I've just picked up a 7D and have a question about filming with it. I've watched a ton of tutorials but can't get a clear answer.

A lot of tutorials say to only film at 1/30 > 1/50 shutter speed. What is the reason for this? Apart from screens and lights not being displayed correctly is there any other reasons?

If I am fliming stuff that doesn't feature artificial lights is it OK to adjust shutter speed accordingly or do I have to purchase an ND filter?
