Pentacon 50mm f/1.8 (M42)

Did a review of the Pentacon 50mm f/1.8 (M42) on my blog.
Here are some of the test shots.
B&W shots are analog and are taken with a Chinon CEII Memotron and AGFA CINEREX (X-ray film)
Color shots are digital and are taken with a Canon 500D.

My review has more and hires images which can be found on my blog: Pentacon 50mm f/1.8 (M42) Review

It is one of the few non-pentax manual lenses I have and I love it.

There are lots of very nice non-pentax lenses for M42 and this is definitely one of those.
But lenses that beat the Pentax versions are probably quite easily counted however.

Something I've found with this lens that wasn't covered in your review: coma. Heavy, heavy coma that sets in very quickly as you move away from the centre at wide apertures.

Overall I like it, but I find I have to be careful using it in low-light situations.

That is something I have not tested very much but that would not suprize me.
Don't thas this problem usually go hand in hand with lenses with bad corner sharpness?

Many thanks for pointing this out and keep snapping!

Would make sense that the two are connected. Though all my other lenses that have notable edge softness tend to be too slow to use in low-light situations, so I haven't had a chance to test them out in that regards.

My main surprise with this one was how close to the centre it kicked in. You can already see it on the bulbs in the "b" in this image taken with my K20, for instance:



(By the way: thanks for doing all of these. Gives me a nice sample set to check when I'm thinking of picking up a new old lens.)

I can add a few photos. My copy of the lens has what appears to be some sort of separation at the very edge of the front element. Doesn't seem to cause trouble on APS-C. All of these are f/1.8.

This lens has very interesting bokeh. I’m not posting images at infinity or with closed down aperture, but IMO in this cases Pentacon loses its magic and turns to just an average 50 mm lens.

This lens is also known as Meyer Optik Görlitz Oreston 50mm f/1.8. The electric version of this lens has electric contacts, but they are of no use to modern cameras. Either way, this is my Pentacon 50/1.8 electric Multi Coating








The last one shows the typical swirly bokeh of the lens:
