![]() ![]() In general, the development of the line proceeded as follows: Helios-81 AUTOMAT -> Helios-81 M or N -> MC Helios-81 M or N -> MC Helios-81 N -> Arsat H. The Helios-81 lens family includes many models and their modifications. Helios-81 is a descendant of the Helios-65 ( HELIOS 65 AUTOMATIC 2/50), which, in turn, is a shortened descendant of the lenses family Helios-44. The calculation of the difference in the relative aperture (count the aperture) is performed elementarily: (5.6 * 5.6) / (2 * 2) = 7.84, which is rounded to the value '8'. In numerical terms, this means that Helios-81 is approximately 8 times brighterthan, for example, whale Nikon DX VR AF-P Nikkor 18-55mm 1: 3.5-5.6Gwhich use a maximum relative aperture of only 50: 1 over a 5.6 mm focal length. ![]() three steps wider aperture of f / 5.6, which is used in 'dark' kit lenses at the long end. ![]() Many people just want a fast prime, especially in addition to their stock / kit lens. Photo enthusiasts often use it as a portrait lens. It is difficult to overestimate the creative potential of such fifty dollars. If something is not very clear, or if you want to be 100% sure that the future purchased lens will please you - ask here in the comments, or contact me according to my personal contacts. Lenses series Helios-81N AUTOMATIC have a different mount, for which there are no adapters for any cameras (the appearance of lenses HELIOS-81 2/50/53 AUTOMATIC shown here). And also by no means do not purchase lenses marked 'AUTOMATIC'. I strongly advise against messing with these early versions (shown, for example, in the 'Appearance # 3' section). Here is such a paradox - from the best to the worst is just a step. Later and better versions have a serial number in small print on the side of the aperture control ring. These options have many mechanical problems. Early versions are easily distinguished by their wide focusing ring and serial number near the front lens. If the latest versions are indeed some of the best stock lenses from Helios family, then early versions are the worst. On average, Helios-81N can be found for $ 30.Ĭritical: there are many different variants of the lenses of the Helios-81 H / M / AUTOMAT family. The bulk of the lenses of the Helios-81 family do not require any adapters and work similarly to the original manual Nikon Nikkor AI / PRE-AI lenses.Īlso, the popularity of the lens is associated with a special twist of the background, inherent in many lenses of the Helios family, as well as good optical capabilities at a fairly low cost. In my opinion, Helios-81 earned its popularity due to its compatibility with Nikon digital SLR cameras with Nikon F mount. Helios-81 can also be used as a portrait and creative lens on modern cropped cameras. ![]() On full-frame cameras (film and digital cameras with a frame size of 36 x 24 mm) it is standard (in terms of focal lengths and angle of view) and is suitable for everyday use for a wide range of tasks. This lens is most often called a 'fifty-kopeck piece' because of the focal length of 50mm. MC Helios-81H 2/50 (or MC Helios-81H 2/50, or Arsat H 50mm 1: 2) - is one of the best standard lenses of Helios family. MC Helios-81H 2/50 lens on the camera Nikon AF N8008s. ![]()
