In a Italian antiques Fair i found this projector lenses.
the boys of store told me that this a lens of a collection .
on it there's f 95 mm . N 43335
the initial price was 95.27 but now after many month is 47.00 $ .
In this place this is the more expensive lens.

Worth trying out if you get it for a good price! Here is how to mount it (my way):

i've buyed it . In the next week i search to mount it on camera.
This market is full of old cameras and lenses ,old super 8 -16 mm , and used materials for darkroom. Fortunally nobody buys them . Today I found a unknown lens for me
It's a topcon. I think that topcon was a japanese industry.
there's a label on it. 1 :4.
Now I don't know if is 1.4 o F4. but I think that is 50mm.
The price is about 11$ . Someone know topcon lenses?is a good? can i mount it on my fuji mirrorless camera?

That particular Topcon/Topcor(yes from Japan) lens has the UV/UNI mount, it's decent lens, but there are not any commercially available adapters, other than a few made by enthusiasts from old cameras. Topcor R, F, and RE are the ones to look out for, they have a modified Exakta mount.

Yes, it's a Zeiss, probably their cheapest lens, it's a Tessar, a decent little lens.

I'm searching to build a kit of lenses for my mirrorless . I've only a hexanon konica 40mm 1.8 and hexanon 135 mm. In this month , i 'm going to do a few travels around Italy , for this i'm searching another lens focals. I wish a wide angle and a 50mm lens . In this big store, there's : aus jena 2.8 ( few euro ) Meyer optic domiplan 2.8, Ricoh with camera and another 50.mm maybe a mamiya..
the price are cheap.
For you , what can I buy?

The Ricoh 50mm f2 is an exceptional lens and usually very cheap.
It is in Pentax K mount so you will need a Pentax - K mount adapter for your mirrorless.
The other lens I do not recognise

Honestly, I think you should stick to one mount, Konica Hexanon AR lenses are very good, look for the 21/4, 24/2.8, and 28/2.8 for the wides, the 50/1.4, 50/1.7, 55/3.5, and 57/1.4 are all good, the 57 has more character.
Familiarize yourself with the common mounts, save these 3 pages to your phone:

Generally avoid anything with electrical contacts, unless you know what you're looking for.

Consulting the forum is fine, but it's no guarantee, you are still responsible for assessing the lenses condition, it is your money after all.
More information about the lens is a big help in advising you, A picture of the whole ID ring or it's information, brand/name, FL in mm's, it's speed f2.8? and it's mount, what ever you can tell us makes it easier to advise you.

If they are real cheap, buy them all, post pics, then we will tell you which to keep.

That 2.5/28 is made by Kiron, it's quite good, not very sharp at f2.5 but quite sharp from f4, it is better at close distances than far away so not a good lens for landscapes.

The Paragon may be made by Cimko, I would need to see a picture of the lens to say.

Kiron used the Panagor brand.

Brand names of lenses are often similar and confusing! Smile
