BEWARE

The specs for this high quality and expensive gear ring states it is .8MOD gear. BUT unlike the cheaper or included gear rings does not match up to an Edelkrone FocusOne (also .8mod) resulting in slippage AND vibration between the gears when using. A complete waste of money? I wonder what follow focus works with it?

Fits lens perfectly!

Super easy install, I just followed the included instructions and it is now very snugly fit onto my lens with no slipping. Would definitely consider purchasing another in the future.

Will this fit the Zeiss Milvus ZE 85mm and 100mm?

Will this fit the Zeiss Milvus ZE 85mm and 100mm?
Asked by: Richard
The Simmod SIMple Fit Follow Focus Gear (XXL, 10mm) will work with the ZEISS Milvus 100mm f/2M ZE Macro Lens for Canon EF (BH #ZE1002MZE), but for the larger ZEISS Milvus 85mm f/1.4 ZE Lens for Canon EF (BH #ZE8514MZE) you will need the bigger Simmod SIMple Fit Follow Focus Gear (JUMBO, 10mm), BH #SISF10JUMBO.
