All you need to do is have a look at the guide below and let us know what the dimensions of your Focus Gears will be. All dimensions to be supplied in Millimetres (e.g. 120.5mm). 
 
The easiest way to get a snug fitment is to take a strip of paper, wrap it around the lens and mark the circumference. Then measure with an accurate ruler! From here via this link calculate your diameter and send it to us. 
 
Please note that we are not responsible for any bad measurements or wrong information given to us. We are happy to help, so if you have a question or are unsure please let us know!
