Imho It Is The Best Choice.

It looks like paint strokes in the pictures of artists. I quickly found out that there is a cult following for a lens called a helios 58mm f/2. These last two versions came in m42 mount, as the old m39 had been almost abandoned by all manufactures.

The Lens Formula Didn't Changed At All, Its Just The Quality (Or The Lack Of It).

They were made at different manufacturing plants over that time, and there are several iterative versions. Most are good but these are the lowest quality versions that you can buy. They look very different, the older one being a preset, smaller and with a deeply recessed front element, while the newer one is an auto lens, bigger, fatter and with completely different materials, engravings, etc.

The helios 44 was the first from the series and it used the m39 mount. I then realised it is a slr lens. During background research into the use of thorium oxide in optical glass i have never come across any mention of this material being used in any of the helios lenses.

However, There Was One Thing That Both Of Them Lack.

Is there an adaptor than can be used to use the helios on a rangefinder like the canon p? The helios 44, and all its variants, is a 58mm f/2 lens (minimum aperture is f/16). As they were so mass produced there’s different variations from different factories/years and i didn’t know if one version was better.

And The Other Is A Slightly Newer Design, The 44M:

Lovely, unique bokeh makes your shoots stunning and amazing. The helios 85mm makes for a better portrait lens, however, in my opinion. In general, both factories stuck to the original design and formula.
