Varavon SLING Follow Focus (Black)

Comments about Varavon SLING Follow Focus (Black):

This is more useful for zoom adjustments rather than focus. When trying to mount the SLING on my Canon Rebel T2i, it doesn't fit tight enough on the focus lens, and as a result, it keeps slipping off. The grooves on the handle are made to fit around the zoom lens instead.

The Sling Follow Focus works very well for such a seemingly simple device. One just needs to install it on a lens that has a large enough barrel diameter - the sling may be too long to wrap tightly around the lens and the 1/4 moon-shaped hard plastic handle might not fit snuggly.

This item is to help me with manual focus on my 5D Mark II while shooting video. It is very inexpensive and a life savor! It enables me to use the tips of my fingers to focus (on the sling) - instead of my whole hand (around the focus ring).

So I bought this as a last option since I have been unable to find a cheap follow focus choice for my MFT SLRMagic Prime. This looked like a really good idea. The handle has teeth on the end to grip into the grooves of a lens barrel. The rubber strap goes around the lens with a string feeling rubber. The handle feels a little cheap. The price isn't so justified. I think it only costs this much, because there isn't an alternative to this style of follow focus. Anyway, I'll get to the point if it worked or not. As designed, no. You need a lens with a wider barrel. If I had to guess, the lens barrel would need to be about 1 1/2" to 2". My SLR Prime has a barrel diameter of about 1". But what I did to sort of get it to work was to wrap the strap around twice and double loop it. It initially misses but for a minor brief moment, so it's still functional. I don't recommend this as an option for small lenses. I'm just making this work because it's better than actually buying a real follow focus. I will say that this tool could be used on many lenses so it sort of has an extra value when you have the right size lens for it. I recommend this tool for Nikon, Canon, and other larger lens sizes.

It seemed great when I took it out of the package, but there was not a hole short enough to fit around some of my lenses (a pentax-m 50mm f1.4, and Pentax-a 28mm f2.8) so I truest burning a new hole into the rubber or whatever material it is, and when that didn't work, I tried cutting it, but as I was afraid of, the band is made of that kind of rubber that when there is even the tinest hole or cut, it'll just keep on ripping until it rips in two. This happened to me. But after many different attempts to mend it (no type of glue will stick, and no heat will melt it) I just used a rubber band to hold it together and it actually works pretty well. Better than the orignal as I can get a tighter fit. But all this can be avoided if your lenses aren't too big. If your lens has a filter of 52mm or greater, then you should be fine. If your lens is 49mm or less, it probably will not fit very well. So your leica, micro four thirds, and older film lenses probably will not fit this product.
