The Platyball is available in two versions — the Ergo and Elite. The difference? The Elite comes with an electronic leveling indicator — the first of its kind. Both models support up to 22 pounds, meaning it’ll work with just about any interchangeable lens camera on the market.
The Uniqball UBH 45XC Ball Head with X-Cross Clamp is perhaps the most unusual ball head I have ever used. And I’ve used pretty much all of them.
