Matar 10,5cm 4.5 (PZO)

[landstrykere]

I got an enlarger from the 50's/60's, an old Krokus (1st version), for up to 6x9 with diverse accessories. The lot came a 6x9 enlarger lens from PZO, which I have never seen before, 10,5cm f4,5 under the name Matar.
A search online in polish brought no results excepted a 2018 listing on the polish online second hand site Allegro:

there are in this size 10,5cm Amar lenses but no Matar. Otherwise I know PZO besides the Krokus enlargers, for some repro lenses used like the usual soviet ones for large format.

This Matar has a red P and focal is in cm like older lenses, but the mount is M42 and it doesn't look to me like an insert ring, so I'd say it's from the 70's ???
Probably a Tessar scheme like the majority of soviet block lenses.

It opens f4,5 to 11 (5,6 - 8 ).

I will test this Matar in order to compare with my Industar-23U 110mm f4.5 and Belar 105mm f4.5 but decided to play a bit with it for general purpose photography.
Wanted to test on film, some BW and some Ektar-100 but I was late today so just grabbed my old Canon 5D with a M42 mount, and put together a tube from parts and a helicoid and shot couple pictures before night.

here I used a strong old OSRAM Nitraphot BR 500W to illuminate the table. Some reddish reflection on the Vega lens:

I keep searching a bit but still no data about this lens.
One is for sale now on Allegro for 89 złoty:

otherwise I can't find specs about differences with the other PZO Amar and Mikar that are seen often around.

Interesting. Not great for general use but it seems like close images are better than distance ones. Weak contrast typical of uncoated or single coated optics of days past. Never heard of Matar before this post. Thanks.

Interesting choice of the name.
In spanish it means - to kill -
Must be an irony somewhere.

The designer of Matar and Euktar lens was prof Jan Matysiak of Warsaw Technical University, so in the manner of adding "ar" like in Tessar or Planar etc. to the first three letters of his name came the "Matar". The lens was probably not for spanish market
