Here a small simple review of the Meyer Görlitz Trioplan 100mm f/2.8 lens

First some samples - made with a Canon EOS 5D - wide open at 2.8. Only with this aperture setting the very special soap bubbles / edge boosted bokeh is there.
Most or all images are linked to bigger versions - may have ~2 MB file size!


And here an image stopped down - the unique bokeh is away - but now the lens is sharper.



All images are processed in Adobe Lightroom, but no pixel harmed with Photoshop.

The better pictures are in my nature-gallery!



My lens is with M42 mount, aluminium version - with a simple M42-EF adapter it can be used with Canon EOS cameras - still reaching infinity.
Lens mostly used with original hood. But sometimes I take the hood away, to get more flare.

Conclusion:

The Meyer Goerlitz Trioplan 100mm/2.8 lens is a lens that could make very special images - used wide open. But it lacks a bit contrast and sharpness, at least at 2.8. But without the 2.8 setting this lens would be a boring normal 100 mm lens - and not the lens for special effects.
One can use the lens very good with extension tubes - but for sharp contrasty macro images it is probably not the best choice.

Alternative Lens Setup:

I found that the Meyer Görlitz Diaplan 100mm f/2.8 gives the same image rendering and sharpness.
Furthermore the Pentacon 100mm f/2,8, the Pentacon AV 140mm f/3.5 needs more testing, not sure about that.
All these projection lenses are at the moment very cheap to get. But it is very helpfull to get a focus carrier for better DIY focus mounting. I used cheap manual extension tubes ad tube, and the original lens holder and lens - one for all three alternative lenses.

First: All three 100/2.8 lenses. The Pentacon 100/2.8 is still uncleaned as I bought it - for some test images.



And here more detailed pictures of the Trioplan sisters, and the 135/3.5 in my DIY mount for theses projection lenses, and right side my DIY mount with the Diaplan inside.



Furthermore it seems, that the Meyer Görlitz Priomtar 135mm/3.5 has a more or less similar bokeh drawing - found on MFlenses.com.
