  1. Dates: zenitcamera gives 1957 as the year of GOI's calculation; Abramov heads his page '1965–1974, KMZ, Arsenal', which matches his dates for the Kiev-10 itself, so the end year may be the camera's rather than the lens's. Christopher Osborne dates the Kiev-10's introduction to 1964, a year earlier than Abramov. Abramov says later Kiev-10s came with the Helios-81; an owner on the MFLenses forum writes that the Helios-65 was made only for the Kiev-10 and quickly replaced by the Helios-81 on the Kiev-15. The page uses Abramov's 1965 as the first year of production.
  2. Helios-65 against Helios-81: zenitcamera and Abramov give them separate entries; Abramov's Kiev-10 page calls the later lens a Helios-81 2/53. Christopher Osborne, who collects the Automat system, writes that the differences seem to be only a matter of styling. The MFLenses owner says the Helios-65 was an attempt to shorten the 58 mm Helios-44 and resolved less than it, and that the Helios-81 gained resolution from lanthanum glass; he gives no source. They have separate pages here until a published prescription settles it.
  3. Resolution by the technical specification (по ТУ), via zenitcamera: 35 lines/mm at the centre and 15 at the edge; Abramov gives 35/14. Zenitcamera's film-resolution curves are GOI's data of January 1959. Field 45° on 24 × 36 mm. Zenitcamera also lists a version for SLRs with the M39 × 1/45.2 Zenit thread; no example of it has been seen, so it has no row here.
  4. Prototypes: Abramov pictures a GOI prototype engraved ГЕЛИОС-65 F=5,2см 1:2 №5016055. Leitz Photographica Auction 8 sold lot 766, 'Arsenal Helios 65 2/52mm', serial 1, described as a prototype lens for the Kiev-10 with an aluminium mount, for €240 with premium (estimate €400–500). Both prices on this page are auction results; no Soviet list price for the lens has been found.
  5. Filter: allphotolenses' database gives 49 mm and 6 blades for the Helios-65 without saying which version it means; the television lens has 13 blades by its owner's count. Neither figure is structured here.
How to tell them apart (expand)
  • Every version is a 52 mm f/2 of six elements in four groups, f/2–22 and 0.5 m closest focus by GOI's data; the Automat is engraved 2/50, the GOI and television lenses F=5,2 см or F=5 см
  • Read the name and the rear: АВТОМАТ and no aperture ring is the Kiev-10 lens; Ц is the Zenit-4-line lens; Т the television lens; a silver lens with a short thread is the M39 rangefinder version
  • Not the Helios-81 Automat, its successor on the Kiev-10 and the standard lens of the Kiev-15, and not the Helios-44 58mm f/2

Helios-65 Automat (Гелиос-65-автомат), Arsenal, Kiev-10 bayonet:

  • Front ring engraved ГЕЛИОС 65 АВТОМАТ 2/50 with a six-digit serial, the name split around the ring without a hyphen (examples pictured by Abramov and on Wikimedia Commons)
  • Focusing ring with a knurled black grip interrupted by bright metal blocks, a bright chrome ring at the rear and a depth-of-field scale from 22 to 22; the Helios-81 Automat that replaced it has a plain ribbed black grip without the bright blocks and is engraved ГЕЛИОС-81 2/50 АВТОМАТ (Abramov's Kiev-10 page)
  • No aperture ring: the stop is set by a dial on the Kiev-10 body (Osborne), so a Helios-65 with a focusing ring alone is this version
  • Arsenal's Automat bayonet at the rear, which only the Kiev-10 and Kiev-15 take

Helios-65 (Гелиос-65), KMZ, M39 rangefinder thread:

  • Bright silver barrel with a black front ring engraved ГЕЛИОС-65 1:2, KMZ's prism-and-arrow logo and a very low serial (Abramov's photograph); the aperture ring is on the barrel, unlike the Automat
  • Short M39 thread at the rear for rangefinder bodies (28.8 mm flange), with rangefinder coupling

Helios-65Ts (Гелиос-65Ц) and GK-65Ts, KMZ, Zenit-4 line:

  • Ц after the number, for центральный затвор, central shutter; transliterated Ts or C
  • Bayonet for the leaf-shutter Zenit-4, -5, -6 and -11, not the Kiev Automat bayonet; Abramov pictures a black lens on a Zenit-11 with bright blocks in its knurled focusing grip, KMZ's logo and the engraving ГК-65Ц 2/50 №00008

Helios-65T (Гелиос-65Т), KMZ, television version:

  • Engraved ГЕЛИОС-65Т 1:2 F=5см with a six-digit № serial and KMZ's logo (Abramov's photograph, №000105)
  • Small barrel made for a television transmitting device; it needs a home-made or improvised adapter on a camera

Serial-range notes

65xxxx–66xxxx (Automat)
The Automat examples seen carry six-digit serials beginning 65 or 66: 651382, 660056, 660302, 662320 and 662469. Soviet lenses are usually dated by the first two digits, which would put these in 1965 and 1966. No serial table has been published. The other lenses seen have low serials that do not date them: 3 and one ending 0002 on rangefinder lenses (Leitz, Abramov), 00008 on a ГК-65Ц (Abramov), 1 on a Kiev-10 prototype (Leitz), 000105 on a Helios-65Т (Abramov).

History

The Helios-65 is a 52 mm f/2 standard lens of six elements in four groups, calculated at the State Optical Institute (GOI) in Leningrad in 1957. Its name lives on mostly through one version: the Helios-65 Automat, the lens Arsenal in Kyiv fitted to the first Kiev-10 SLRs, from 1965 by Abramov’s dating (Osborne puts the camera’s launch in 1964). The Kiev-10 sets the aperture from the body, so the Automat lens has a focusing ring and no aperture ring, and it fits only the Automat bayonet of the Kiev-10 and Kiev-15. Abramov writes that later Kiev-10s came with the Helios-81 instead. The Helios-65 Automat was therefore a lens of the first years, and the examples seen all have serials beginning 65 or 66.

The other versions pictured carry the logo of KMZ at Krasnogorsk. Zenitcamera, working from GOI’s 1963 album and KMZ’s 1971 catalogue, lists a lens for rangefinder cameras with the M39 thread, one for M39 Zenit SLRs, a Helios-65Ц for the leaf-shutter Zenit-4 line, and a Helios-65Т that projected a 24 × 32 mm image onto a television tube. Abramov adds that the Ц version served the Zenit-4, -5, -6 and -11, and pictures a ГК-65Ц on a Zenit-11. The silver rangefinder lens survives in very low serials: Leitz sold serial 3 as a prototype for €4,320 with premium. An owner on the MFLenses forum who adapted a television lens to a Sony A7 counts 13 blades in it.

Whether the Helios-65 and Helios-81 are really different lenses is not settled. Zenitcamera and Abramov give them separate entries, with different names and focal lengths (52.48 mm here; Abramov calls the Helios-81 a 2/53). Christopher Osborne, who collects the Automat system, thinks the difference is mainly styling. An owner on the MFLenses forum says the Helios-81 resolved more thanks to lanthanum glass. On the Kiev-10 the two are easy to tell apart. The Helios-65 Automat is engraved ГЕЛИОС 65 АВТОМАТ 2/50 around the front ring and has a black focusing grip broken by bright metal blocks. The Helios-81 Automat has a plain ribbed black grip without the bright blocks and the engraving ГЕЛИОС-81.

For a buyer the lens is rare and hard to use away from its body. Mathieu Stern found no commercial adapter, only a home-made one offered on eBay for close to $200, so he 3D-printed a Kiev-10/15 mount from a free model to use the lens on a mirrorless body; he liked its strong swirl and sharp centre. Check that the focusing ring turns smoothly over its full travel and that the blades are clean and dry, since the stop can only be set and checked on a Kiev-10 or Kiev-15. A lens sold on a Kiev-10 may have been swapped, so compare the serial with the body’s era. A Kiev-10 offered with a Helios-81 is the later standard outfit, not a missing Helios-65.
