I'm not sure about contours and stuff, on a sunny day they would be sweet but if the cloud came in then dunno aye, all depends on the kind of lense that you have, they seem to be all good, I have some friends that use them and like them, I personally don't like them that much but that's just my 0.02, they are all good though.
