Computar 2.8 28mm M42 samples and thoughts...

Ok.

A few days ago a fellow Pentaxian posted this on the price watch:
https://www.pentaxforums.com/forums/pentax-price-watch/215195-bnib-28mm-f2-8-...6-shipped.html

So I bought one for the lofty sum of $16 shipped.

It arrived today, And here are some initial thoughts and silly samples.....

It is small, like a M 50 2, All metal it seems and labeled "Japan" (if that means glass made there or the whole thing, I dont know)

Focus ring is smooth and stops click in nicely.

No Auto/Manual option so you compose wide open and then meter at your chosen aperture.

Looks like 5 blades in there.

Came packed in a white box, Styrofoam inserts. Well packed.

Next are some samples, I did not get outside yet but I will update as I shoot more.

Starting with a image of the lens itself.

(all images are straight out camera Jpegs, No PP.)









As I said, More later and hopefully other people who bought this cheap thing will show some as well.

Any questions feel free to ask.

Eric

This looks as if it might be a member of 'The Great Vivitar 28mm Bestiary' - No M22 on the list ?
See the following link:-

Great Vivitar 28mm Bestiary: Details

Very often unusual Makers names appear on lenses made by well known makers and again there was a lot of 'cross-fertilisation' amongst the Japanes lens makers.

Just a thought ?

Thanks for starting this thread Eric.
Nice shots!

Just got mine, slapped it on the K-01, and snapped a few.
I was seeing a bright view on the display even when stopped down.
Seems very sharp to me.

Ya I am curious

It reminds me a bit of a Tokina lens I have.
I guess they have a pretty generic look

A few more, all wide open.

ISO 800

90 degree throw of the focus ring, so it locks on fast.
Non rotating front element.
Tomorrow I'll try it on the Q.

Pretty impressive! I didn't jump on this when I had the chance, kinda kicking myself now But I'm overstocked on 28's already, so I'm glad a lot of PF'ers were able to grab one of these.
