Excerpt: I purchased this 75mm half ball adapter so I could put various tripod heads on various legs. The most notagble being a 3' slider that I attached directly via the 3/8" threaded screw. I works great, and allows me to attach my slider to one set of legs but have a ablilitty very quickly level the slider and lock it down. The bottom lock in tight enough that there is zero movement, even then the camera is a the farthest point of the slider.
Excerpt: I really love this item because you can level your camera so easily. It's also short handle so its not bulky or anything like that. It also goes really well with the manfrotto tripod 535. <br />Overall, I would recommend this to anybody who uses DSLR for shooting.
Pros: Easy To Use, Improves Tripod Function, Solid/Sturdy
Excerpt: Exactly what I was looking for. I use this with my existing Manfrotto 546B Tripod. I add a Kessler Crane Quick Release base to the half ball and on my Kessler Steath Slider. Next, I add Kessler Quick release utility plates to both the bottom of a 502 Video Head and the bottom of the Slider. With the QR and half ball installed on the tripod, I can quickly switch between mounting the video head or the slider on the tripod.
Pros: Easy To Use, Fits Well, Improves Tripod Function, Solid/Sturdy
