Produced at the MMZ plant in 1966 in excellent condition, MMZ lenses are considered to be the highest quality Helios lenses since the mid-60s. A varnish was used to cover the lens, not just paint. This lens is one of the first lenses that were produced at the MMZ factory after transferring production from KMZ to several other factories (Belomo, Valdai), which took place in 1966.
