The 37mm Close-Up Lens Kit from Kinotehnik is an optional diopter lens kit, designed for those who cannot shoot with a viewfinder loupe while wearing their glasses. It enables you to choose the desired power of the diopter setting by adding the appropriate glass lens to the viewfinder. The metal thread is found under the viewfinder's eye cup, and is compatible with the LCDVF 3C model only. The kit contains +1, +2 and +4 corrective lenses, and any two of them can be combined together, creating custom diopter settings when necessary.
Compatibility
The 34mm Diopter Kit is only compatible with the thread unique to the LCDVF 3C loupe, designed for the Canon EOS 5D Mark III and EOS-1D X DSLR cameras.
Provides Additional & Customized Correction
The three +1, +2 and +4 lenses included in the kit provide additional diopter correction, and you can combine them for an even greater range of values.
