Kodak Ektar 63mm, with helicoid, probably from photo-printing machine. I have removed constant diaphragm. Heliar-type optical formula? Low contrast, but high resolution.

Very nice one! Attila and I have the cine version f2/63mm of that lens, outstanding performance!
Mine see: https://www.flickr.com/photos/kds315/sets/72157631943886461/

Could you show a picture of that lens? I guess it is a printing Ektar....

Thank you, Attila! I have enlarger Ektar lens too - 75mm and 100mm. But 63mm have constant built-in diaphragm (i remove it)... and probably not enlarger lens

I see, that is surely not enlarger indeed.

Congratulations on acquiring this lens and thanks for the great pictures.
This certainly looks like beautiful Heliar bokeh to me.

If you don't see what I mean, just compare the out of focus areas on the above two pictures to the rendering of the Ektar 75/4.5 on the following picture:



Cheers!

Beautiful, soft rendering… I love it.

I have a Printing Ektar, 85mm. I don't believe any of them come with helicoids. It is almost painfully sharp.

Could you have a Micro-File Ektar? It seems that lens did come in that length with a built-in helicoid.

I think you're right. I own a Micro-File Ektar 63 mm and it has a helicoid and seems pretty sharp at close distance:

C-sharp, eh? by simple.joy, on Flickr

I wouldn't say that it has low contrast, but I didn't remove the constant diaphragm, so maybe that's a factor besides my use so far being limited to close subjects as well... There also is a lens with a grey (plastic) front only labeled "63 mm Ektar", which could be the same, but I don't know - have only seen an image online.

I have a Printing-Ektars as well and like it a lot for bokeh- and flare-experiments - a really fun and also quite sharp lens. I can't say if they're the same but I think both could be Heliar designs, so they might be similar.

So, I have no idea if that's a similar one than you have, but this is how mine looks like:





But as mentioned before... it could also be like this one:

(not mine)

It's called "projection lens" by a seller, but I'm not sure if that's accurate. It's possible that its optics are identical to the "Micro-File Ektar", but who knows...

What I can say for sure, is that I find the image quality of the Micro-File Ektar very impressive:

Maybe micro fiche, micro film lens? Micro "file" - a lens dedicated to file reading, which almost certainly will be micro film archival work.

On the other hand, it could be completely, utterly unrelated, and just something they picked like Ektar.

Yes, indeed - I'm sure this was used with microfilm. I just don't know if it was to reduce large formats to microfilm, or to enlarge back from it and make prints. According to the user "Old Lenses New Camera" on flickr (https://flickr.com/photos/49576306@N08/albums/72157686954264941) it's documented that it was part of the "Recordak" microfilm system and according to the information available to him, it's a 5/3 Heliar/Dynar design and from 1951.

However that doesn't confirm anything about the lens mentioned at the start of the thread, because we still don't know what it looks like and if it's a similar type or not.
