The Helios 44M is a normal fast lens manufactured in the Soviet Union. Process since there are many versions of the 44M, and the tutorial The progenitor of its 100mm series E, produced by Cosina for Nikon, does not give diffraction scattering at all up to f800 on the 8th Nikon.WARNING: in spite of extensive adjustments, my lens still cannotįocus to infinity it is short-sighted to about 6m.

But Arsat 100 / 2,8 is sharp in the center with an open one - only on the edges of the software gives. AF DC 105/2 behaves similarly and strongly dislikes backlighting. And further on the figure, diffraction spoils the contrast already from 8, after 11 the resolution drops ugly. Nikkor 105, then acquired, although it belongs to the professional class, has a masterpiece quality of mechanics, but the optics is such that its actual working diaphragms are from 3,2 (half between 2,5 and 4) to 5,6.
At one time, completely foolishly, I sold it. And the Arsat 100 / 2.8 is no less successful copying of the Nikorr series E, which surpasses the legendary Nikkor 105 / 2.5 in sharpness. As far as I understand, this is a successful copy of the Nikkor 50 / 1.4 non-Ai six-lens symmetric anastigmata of the early 70s. I had such a fifty dollar - alas, it broke mechanically (terrible build quality). Perhaps I have not the most successful instance, but the lens looks great in appearance. In general, image quality could be better. On aperture 1.4, strong software, on such aperture you can get good portraits. Unlike the legendary Helios-81H, Helios-123H does not spin the bokeh. Discs in the blur zone are well-defined with a thin edging, blurring is smooth. It is hardly possible to distinguish by eye the work of fifty dollars with closed diaphragms. The contrast at fully open aperture could be better, the contrast increases with closing the aperture. The color rendering of the Helios-123N lens is normal, there is no characteristic “bottle tint”. The lens has very little distortion (there is practically no distortion on the crop). Aberrations are the main problem high-aperture lenses. For example, fast Nikon 50mm F1.2 is losing HA already at F2.0, but its cost is also much higher. Good sharpness begins after F2.8, the lens suffers from spherical aberrations on open apertures (the edges of the contrast elements are blurred). Roughly speaking, old lenses are more versatile in relation to different systems than modern ones, but working with old optics is much more difficult.Įxample photos on ARSAT H 1: 1.4 50mm.

But modern autofocus lenses cannot be just as easily used on old cameras, as most lenses do not have manual iris control, and autofocus only works with native cameras.

How to use on Canon can be found in my article old lenses at canon. So, MS Helios-123N can be used without problems on Canon, Pentax cameras. Old manual lenses (with manual focus) are interesting in that they can be used on other systems (on cameras from other manufacturers) without regret that autofocus will disappear. Lens AI-S such as the old and new modern native Nikon lenses, for example Nikon 50mm f / 1.4 AI-S. At MS Helios-123H 1.4/50 The same mount (mount) as Nikon lenses. Yes, MS Helios-123N just installed on Nikon. The lens is very interesting for its huge aperture F1.4 and compatible with the Nikon Central Control Arm.
