I bought mine a while ago and while I was looking up the ebay link for this write-up, I found out that this FF now comes with both L-shaped bracket and the standard 15mm rod fitting mount, which is absolutely amazing. No other FF offers you both mounting options, although the L-shaped adapter could be adapter to many other FFs. Someone should start selling them separately.
Anyway, if you’re about to buy your first follow focus and don’t yet have your 15mm rod setup, I think this FF could be the one to go for. When you decided to buy your 15mm rod system you’ll still be able to use this FFs with it, which is very cool.
If this FF is not for you, check out the Follow Focus Buyers Guide for more options.
