ARSAT 50mm f/2 fast standard lens for Nikon (D)SLRs!


Native Nikon mount lens – no need for adapters to use in on Nikon (D)SLR!

Also known as “MC HELIOS-81H” – the same lens: made on the same factory just made after 1991 – when Ukraine gained independence and lost the rights to the brand name “Helios”.


Highly recommended lens for NIKON users – allows infinity focus without any adapters!


Very compact standard lens, sharp and contrasty even wide open at f/2.0.

Nikon mount is a way these lenses were made: to fit Kiev SLR cameras that have nikon F bayonet.

So for modern Nikon DSLR you need no adapter – just mount it as you would any Nikon manual focus lens with no problems – APS-C or full frame(no limitations).

Based on double-gauss design Arsat is derivative from Zeiss Biotar, which means in the right condition it will have slight swirls in the background.

From Radojuva.com.ua

MC Helios-81N is one of the best standard 50mm Soviet lenses, which gives an excellent sharpness even at full aperture F2.0. Its interesting bokeh with twisting cyrcles. When using on modern digital-SLR cameras with crop factor, it’s perfectly suitable for shooting portraits. MC Helios-81N without any alterations almost always be able to establish themselves on camera Nikon. And its price is just perfect for the quality of the image.”

Arsat N 2/50 fix lens comparing to kit zoom lenses

Arsat is a vintage soviet fixed focal length(prime) lens, in high demand nowadays for their fast aperture(f/2), which opens up a world of possibilities for photographer – selective focusing, low light photography; for their ability to be mounted on various camera systems via affordable and easily available adapters. It is especially useful for Nikon (D)SLR shooters.

Arsat N 2/50 comparing to Helios-44 series

If you are Nikon user then the native Nikon mount Arsat has obvious advantage from the start – it’s native mount means that you do not need adapter and (very importantly) you’ll be able to focus and compose with open aperture, maintaining bright image in your viewfinder.
On the contrary, if you use H-44 + adapter  you will have to work in “stop down” mode – this means your viewfinder will turn darker unless you shoot wide open.

Bokeh and sharpness will differ as well, this will depend which version of Helios-44 you compare it to: in general earlier Helioses-44 will have more “vintagy” character, will be less sharp but will have nicer bokeh due to more blades in aperture
