I purchased these as living on Dartmoor I wanted to be able to get out and try and get some decent shots with a longer exposure shots of the streams, sunrises etc.This set seemed like a decent price for what was included and I was not disappointed.The set is presented in a lovey soft pouch with a belt clip on the back to either attach to your belt or onto the strap of a camera bag.Inside there are 4 filters, each feels well made and is clearly labelled on the side with the ND value.The attach to the lens thread with ease and don’t seem to cause any threading issues, and if needed they can be stacked.It took a little trial and error for me to calculate exposure times compensating for the extra light needed ( although ND1000 just seems to be 10x normal exposure ).Although I’ve not had a massive amount of time to get out since purchase, the time I have had with them has been fun (and educational). They produce some excellent results and the glass quality really is excellentHighly recommended to anyone wanting to get into long exposure shootingPros- excellent quality- nice storage case- decent price- produce good resultsCons- might have been nice to have something between ND64 and 1000 but can be stacked and I knew this before purchase
