Thanks for the comments.

Just got time this afternoon to compare the flare handling of each lens.

First, the sun in the frame.

I think the Helios has an edge on the Biotar.

I think Ron is right! I like the Helios.

If you just have to find correct version. There is much difference between them.
Cool

Good comparison.

Nothing much between them. The 44-3 may have slightly more swilies going on in one of the samples.

I suspect the Biotar may be sharper, but I cannot judge at this size.

Thanks for the comments.

By the way, below is the front element coating color of each lens.

Helios is an excellent example! Better than the original.

Looks like my copy - mine is from '53 and has some coating damage, but I don't see any issue with photos. It has a semi-auto aperture that needs to be cocked before shooting (spring mechanism), right? I didn't do any testing like you did, but from casual use, I couldn't tell the difference between this and the Helios-44. I was surprised that I liked the build of the Helios more than the build of this Zeiss.

I will say I <3 the flaring 100% more from the Helios! Thanks for posting this!

That Helios is a lens from 1993 with much more modern coatings than the Biotar. Explains the difference in flare and slightly warmer rendering.

It does, however, not explain the better rendering and better sharpness of the Helios ... and FWIW .. my 44-3 shows exactly the same type of behaviour compared to my Biotar "red T" ... ergo, it is a tad better in every respect.

How do both compare with the konica hexanon 57/1,4 and Minolta MC 58/1,4 lenses (aka japanese Biotar).

Contrast + Resolution = 'Sharpness', if I'm remembering my rules of thumb correctly. So a more contrasty, (say better control of flare and veiling glare), coating can provide for better 'sharpness'. Q.E.D. ? So it could be down to more modern coatings, or more accurately, I couldn't rule it out based on the information provided here.

Of course I'm making this argument while looking at something rather obvious - the 'G' on the statues bottom. In terms of delivering contrast, the Biotar appears to be handling flare and glare better than the Helios.

On rendering, I always think of it as a subjective matter, but I could be wrong.

AFAIK, the contrast + acutance + resolving power + flare resistence + nivel of CA = sharpness .

The last is almost always a combo of characteristics of the lens.

Long time ago Sharpness = resolving power.

Not now.

I don't think that exist a lens with "10" un sharpness, because all the designs are compromisos between some corrections of aberrations.

Inside those designs there are one or more of them that like to each of us.

I'm still in love with the Kern Macro Switar 50/1,9 in Alpa mount.

The Helios 44-3 is a very good lens.

A must have
