Vimeo member LJ Lee shares a review on the Lanparte Follow Focus with A/B hard stops, removable marking disc, and quick release 15mm clamp [Thanks LJ]. Lanparte has various DSLR equipment which all have excellent reviews, but they can be a bit pricey at times. This Follow Focus with manual stops can average about $400 dollars on eBay (Click Here for more information).

Nice plug Steven lol. A/B hard stops are nice and my 2nd rig will probably go with this type of FF. Now I just use two Fotga 500 FF... My thumb and the adjustable marker is my A-stop. =)

This is an excellent follow focus and excellent price. I will be distributing Lanparte products in the next few weeks.
