A while back I decided to look for followfocus gear rings for my vintage Kiev 16-U lenses. I bought the complete trio of these lenses for my BMPCC and they look great. But the lenses are quite small and since I’m using them for film I need to be able to pull focus in a handy way.
The cheap “universal” gearbelts aren’t seamless and the Kiev-lens turn at least 360° so they wouldn’t work. Also, these tend to slip a bit so I’ve never been fond of them. There are some cheap rings you can tighten with a screw, but they don’t go below 50mm and my lenses are 44/45 mm in diameter.
So I started to look for specialists. There are some options when it comes to getting custom-made rings which are made to fit the diameter of whatever lens you may have, but most of them start at about $50 a pop. Getting one wouldn’t work because of the different diameters on the Kiev’s, and I wasn’t keen on spending the same amount of money on custom gears as I did on the entire lens set.
Luckily I found the FLEX gears on eBay and asked if they could create some fitting my lenses. It wasn’t a problem. Each gear is about $8 and the quality is good.
The dealer is very welcoming and polite and it didn’t take very long before I received my package. They even added an extra ring for free. Couldn’t be happier.
The gears have industry standard 32 pitch (mod 0.8) and work fine with most follow focus systems. All in all a great find which makes my life a bit easier.
