Zeiss ZF UNCOATED Distagon/Planar DSLR Set (21-85mm)

Note that these lenses are uncoated, in order to generate flare.

Regular Zeiss ZF DSLR lens sets with anti-reflection coatings also available.

High quality EF lens adapters can be supplied without additional charge to allow these lenses to work with cameras with EF mount at no additional charge – please request this when ordering.

VMI Zeiss sets have been modified to include a follow-focus ring which will allow an ARRI MFF1 follow focus to operate without attaching an external gear and the fronts have been modified to give a consistent 80mm donut size.

Some people want to know why we have broken with tradition and do not supply a conventional 18, 25, 35, 50, 85mm set.  This is because these are not a speed-matched set with a common F stop, so this will become 18mm/F3.5 (slow), 25mm/T2.9, then 35mm/T2.0, & 50/85mm both T1.4 .  Instead a 21mm has T2.9, 28, 35mm are matched T2.0 and 50 & 85 are matched T1.4 which we find a better combination.  Also the jump between an 18mm and 25mm is quite large, besides which the 18mm vignettes with the 5D MkII/MkIII, so 21, 28, 35, 50, 85 is a happy compromise!

Zeiss Uncoated ZF Distagon/ZF Planar DSLR Prime Set

• 21mm/T2.9 Zeiss ZF Distagon Prime lens
• 28mm/T2.0 Zeiss ZF Distagon Prime lens
• 35mm/T2.0 Zeiss ZF Distagon Prime lens
• 50mm/T1.4 Zeiss ZF Planar Prime lens
• 85mm/T1.4 Zeiss ZF Planar Prime lens

Front Element screw-in adapters

Note that VMI supplies all Zeiss ZF prime lenses with 80mm front element adapters, to allow them all to have a standard 80mm donut fitting for ease of using matte boxes.

However, these are removable to expose the original screw-in thread to fit screw-in adapters like the Genus variable ND screw-in filters.

However, the Zeiss ZF lenses are really inconsistent. 21mm (87mm); 28mm (64mm); 35mm (64mm); 50mm (66mm);  85mm (77mm).  So if clients want to use screw-in adapters, then we would recommend that they use Canon L_USM Prime lenses instead.
