This followfocus came with a rig I recently purchased and I have no need for it.

Although it may not be a $300+ dollar follow focus, it is surprisingly stout and well assembled and the design is rather ingenious. 

It is 100% functional and trustworthy, I would keep it if I did not have another, but need to sell to add more lenses to my kit!

It works well with my Canon T2i with a 50mm and my 18-55mm kit lens, would work with Nikon and others as well.

It appears to be made out of Lego parts and some other hardware, but don't let that fool you, it is a great little peice of equipment.

If you plan on doing any DSLR or HDSLR filming, you need one of these.

If you are unsure about whether or not you need a follow focus, this would be a great way to start.

It would mount to pretty much any rail system as it is not dependent on any certain rail diameter.

Comes with marking disc for rack focus moves etc. and all the hardware to mount to your rail system.

If you are just getting into DSLR film, you'd be crazy not to buy this inexpensive, yet effective tool to boost your production value markedly.

Bid with confidence, you will not be dissapointed.
