Review on 📸 Fotasy 40cm (16 Inch) 15mm Rods for Rail Rod Support Systems – Perfect Fit for Mattebox, Follow Focus, and More! (2-Pack) by Joseph Long

I bought this with the EZFoto rail system and am very satisfied. Very good device for the price but not 100% perfect. That's what I like. The device is solid. Everything looks and feels high quality. The quick release clamp can be quickly and securely attached to the rails. It is very easy to put on and easy to adjust. The focus wheel works very smoothly and feels high-quality again. The strap that goes around the lens is pretty good. I've used it with the Canon 7D and 5Dmk3, as well as the 100mm f2.8 and the notoriously difficult (because it's physically short) 50mm f1.4. Everything worked smoothly and I had no trouble concentrating. I also added an 8 inch whip from Neewer which was the cheapest whip available. They worked great together. When using tracking focus, you usually need an external monitor. Great job that helps me focus. This tracking focus unit includes hard stops, so in theory you could set your focus points and then return to them blindly. So far I have not been able to achieve sufficiently stable results. got the device the day before filming a live concert because i was practicing with hard stops i couldn't always get the results i wanted sometimes yes sometimes no and i really don't need them for the show anyway. I haven't given them up yet because I think they can be of great use and I don't rule out user error. But for this gig I used the monitor as my reassurance that I hit focus and the results were very encouraging. There may be slightly cheaper options for a combined focus tracking and rail system, but in my opinion the quality and price of this unit represents excellent value for money and certainly offers more value for money competition.
