These are some of the oldest and most rare Zeiss Standard Speeds. The lenses date back to the late 60s early 70s. They are some of the oldest Zeiss 35mm cinema lenses out there. They have their original coatings, and an iris design that is unique to these lenses, and is different than all the other series of Zeiss Standard Speeds. All 5 lenses are f2 / T2.2. The lenses were originally in ARRI bayonet mount, but they have been upgraded by Duclos Lenses and they now have PL mounts, geare...d focus rings, and threaded 80mm fronts that accept 77mm filters. These are some of the smallest and lightest cinema lenses ever made which makes them really well suited for gimbal and drone use. The best detail about these lenses: the optics are pristine. I have never seen glass this old that is this clean. No exaggeration, the lenses look like new old stock, and they are the ORIGINAL COATINGS. It's rare to find MKI Standard Speeds, and it's impossible to find a set with glass this clean. They just got mechanically overhauled by Duclos Lenses and they are ready to shoot. These lenses are ideal for anyone looking for a great set of vintage primes, that deliver an amazing look, and conveniently are really small and lightweight. They are also a great find for someone who is a collector, considering you will never find another set with such clean optics. Reluctantly, I need to sell this set to help pay for a new camera package. I hope they can go to someone who can appreciate how special they are.
