Does anyone know what this means?

Color Formula

Just the incorrect translation for what is called "color contribution index" (CCI)

Thanks. I have a better understanding now, but I still have no reference.

I see two splits above: 10-0-1.5 and 11-0-0

How would the colors be different between 10-0-1.5 and 11-0-0?

The article calls 11-0-0 a rational fall and 11-0-1.5 almost perfect.

The post also says (translated): "However, the "golden mean" is a lot of lens optics of the old school without MC enlightenment."

Does that mean the single coated optics have better color? What is the golden mean?

No, single coated lenses don't have better colour.

Golden mean: https://en.wikipedia.org/wiki/Golden_mean_(philosophy)

Quote:
"the golden mean or golden middle way is the desirable middle between two extremes, one of excess and the other of deficiency."

Dear colleagues,

Can someone please help me by giving me an advice?

I can obtain these two Helios lenses. I need you to tell me what are differences between them. Are coatings different maybe?

The first one is Helios 44 Zebra (https://www.pentaxforums.com/userreviews/helios-44-58mm-f2.html) and from physical construction point of view it looks the same as Helios 44-2 (https://www.pentaxforums.com/userreviews/kmz-helios-44-2-58mm-f-2.html). They both have 8 blade aperture.

Should I be worried about something specifically when choosing between the two? Or perhaps they are mostly the same and nothing to worry about.

Thank you.

Zebra Helios-44 may have either Zenit SLR M39 or M42 mount - check before buying, as most of them are actually M39.
Helios-44-2 is always M42.

Hello to everyone here! I've been reading through this thread for some months and it was very helpful, while i was trying to make a choice in which model of Helios i would buy!

After a lot of search,about a month ago i bought from the same seller 2 Helios 44,one of 8 blades and one of 13 and both are 39 mount and with the bluish coating.

Finally today they both arrived!!! Smile Fortunately they seem in very good condition,as was described!

I have a question about the year of manufacture... in the 44-2 etc lenses it's not that complicated,but in the 44, i can't say i really understood what is going on, even if i read many times post here... Sad

If someone of you can help me figure it out, it would be very kind! Not that it's important the year it was made,but just out of curiosity!

The No0296567 is the 8 blades and the No0174401 is the 13 blades.

I would say between 1961 and 1965. To be more precise, you will need to find a passport of a lens with close serial number.

Hi all,

I have that rare copy of Helios 44-2 with distance in feet instead of meters. Here are some pics. It's a good performer!

We still have strict lockdown here,so i can't test the lens as i want,but the few chances i got to try the 8 blades silver 42,i am very surprised with the color rendering! I almost don't have to retouch anything in my Raw files and i am so impressed specially with clouds and sunsets photos,cause i get the correct colors of what i see with my eyes!

I did not seem to see the link to this youtube video here, so maybe useful for some reason. A guy who collects and modifies Helios lenses explains his 8-groups typology of Helios 44-2 family.

what about N7160525? may be "1967 year"?

I haven't caught this bug. Just thought his ideas could be interesting from some practical viewpoint.

Hi all,

I really hope you can help me as I’ve been scouring resources online for hours on end to try and find an answer.

I have a Helios 44M lens which I use on my 5D Mark IV.. gorgeous lens and I love it. I’ve just purchased an early KMZ 44 M42 (8 blades) but I cannot find information to tell me whether I’ll be able to use this at infinity without it clipping the mirror. The buyer has kindly sent me a photo and it looks like the rear element protrudes by almost 4mm.

I’m hoping someone here has the same lens and has maybe used it on a 5D to give me some advice. Much appreciated in advance!

I just picked up a copy similar to bkwphoto. Very early Helios 44-2 made by KMZ serial number N00700XX and the scale is in feet instead of meters. Yellow color instead of white.

Are we sure the Helios 44-2 with serial number N00XXX.. were made pre-1970?
It came with a camera made in 1971.
I could see it being made in 1970, but it might be a stretch to think it's pre-1970.
Then again I can't confirm that was the original lens to the camera so perhaps it is.
However, didn't Helios 44-2 production start in 1969?

Correction: Seems 44-2 production started in 1967.
