COMPATIBILITY
The HCD 4,0-5,6/35-90 mm lens is not compatible with the converter H1.7x,
the HTS 1.5 Tilt/Shift adapter or the Macro Converter. It can be used on the 60
Mpixel cameras but in the wide angle settings, a marginal automatic crop will
be added in Phocus.
The HCD 35-90mm is designed for use on the H4X, H2D, H3D, H4D and H5D
cameras only.
