Our lenses work perfectly on the best cinema cameras from Arri, RED, BlackMagic, Zcam, Kinefinity, etc.

Please note, if you are planning to use these lenses with 35mm film cameras such as Aanton 235/535, Arri 235/435/535, etc, then you will need a replacement iris ring to get enough clearance above the mirror chamber. We can provide these replacement rings free of charge or install them when assembling your order, so please let us know if you need them once your order has been made.

MIR- 20M 20mm T3.6 (F3.5) is the widest rectilinear lens in Soviet lens line-up. It’s losely based on the Carl Zeiss Flektogon 20mm optical formula. The minimum focusing distance is just 0.18m, which makes it one of the shortest close focusing lenses in its class and a great lens for getting very close to your subject. If you want the maximum depth of field though, focusing to around 2m brings pretty much everything into focus!
