I'm still beating a dead horse here, but does anyone know off the top of their head lenses that have similar enough soap bubble bokeh like Trioplan 100/2.8?

Those are atrociously expensive these days, but I simply must find a way to get my hands on something like it.

Now that's intriguing.

This is a fascinating thread, is there another thread detailing the procedure to get these cine lenses fitted out to use on a digital camera?
Quite something to see some of these results, almost surreal, any tips for the beginner, I'd like to have a play around in this field.

For cine lenses you just need to buy a C-mount adapter and start looking for C-mount lenses on eBay for instance Wink

Cine lenses covers (do not vignette or just slightly vignette) roughly from 25mm and up on m43 sensors.
You need a mirrorless camera
Stay away from C-mount zooms (they usually vignette a lot)

Nice, I've just had a squint on ebay, they cost peanuts!, I would be using them on Fuji X mount, is there likely to be vignetting problems with this set up do you think?

Yes, all the 25mm would probably vignette on your APS-C camera. You need to study the threads in the cine section to see which lenses that can be used without vignetting on your camera. Wink

The Meyer Diaplan and Pentacon AV 100/2.8 lenses look like a 100% copy of the Meyer Trioplan 100 for me.
The 80mm/2.8 with the same names are quite good as well, but after first photos it looks like they have not that much over corrected spherical aberration.

Here Diaplan/Pentacon AV 100 pictures:





After a modification a Sigma YS 135mm/2.8 gives also soap bubble bokeh:

These are all spectacular pictures.

Thank you!
I think for most viewers the last picture with the Sigma YS 135mm is to much soap bubble and color - but I like it.

Wow, that Diaplan/Pentacon AV 100 almost looks like a zoom effect.

The last image was made with the defocus control modified Sigma YS 135mm/2.8 - cyrano´s citation could give a false impression.

Certainly was misleading, if that was the case.

A Cooke triplet often produces interesting bokeh on highlights. This is a Steinheil München Cassarit 35mm f2.8.

At f2.8

@KDS
Your Celestron 300 - is it a Newton or a Schmidt-Cassegrain etc. type?
Because the newton (Celestron 300/76 ~F4) is dirt cheap (less than 70€ (NEW!) without 1,25" T2 Adapter) and I've never seen an SC or dedicated photography version such an short focal length from Celestron.
Do you know about it's coverage? I wonder if it would work for APS-C.

A newton is quite unhandy to use for photography though (despite corner performance), especially when compared to lenses like the Minolta MD 250/5.6 Wink But as it's 100% free of glas and 1,25" filter are quite cheap and easily available it might be interesting for UV work.

Here a few boring samples (most of them from when I startet with photography)

Minolta 24/2.8




Fujian 35/1.7




Cyclop 85/1.5 (version which is identical with Helios 40 85/1.5)






Meyer Domiron 50/2
