RO3-3M - professional cine movie lens

RO3-3M - the lens is designed for professional film cameras operating on 35mm film with a frame size of 16x22mm. 

Produced in a frame for cameras 'Konvas' (KSR-1M, KSR-2). High-aperture six-lens anastigmat. Predecessor of OKC1-50-1.
RO3-3M attracts with fourteen aperture blades and a peculiar picture, sharp in the center of the frame already at F/2.
Some Soviet film lenses are still highly valued by amateur photographers. 

Such lenses have unique or at least interesting optical characteristics. RO3-3M is a bright representative of such lenses.
RO3-3M has a 6/4 Planar type optical scheme, similar to the Biotar scheme used in classic photo lenses of the Helios-44 family. 

Biotar is a derivative of Planar. From here, the similarity of the picture between RO3-3M 2/50 and, for example, MS Helios-81N 2/50. First of all, twisted bokeh catches the eye. In general, RO3-3M is noticeably sharper than most Helios lenses of the 

Helios-44 family.

The RO3-3M lens can be used on mirrorless cameras.
