Hello all
I'm off to Iceland for 3 nights on Boxing Day to hopefully get a glimpse of and photograph the Northern Lights....fingers crossed....
I intend to take all of my lenses in my sig and my 5D3.
Thing is, the fastest lens I have is my aged Canon 28-80L which isn't brilliant wide open. With the high ISO ability of the 5D3, do you think I'll be able to capture the lights well with a 17-40?
Thanks
