Cheers Pete, but where you say you’ve bought several does that mean they wear out just like the Nikon one does. I can get Nikon for £14.99 on the net, or £27.99 as quoted by my local stockist. Was kind of hoping someone made one similar style to the 300 2.8 !Loads on eBay starting at under a tenner.
I have bought several clones an they have all fitted well.
