[M42] Domiplan 50mm F2.8 Review – “Soap Bubble Bokeh” Lens of the same brand as Torioplan

Hello, my name is hiron. I am a vintage lens addict. (Twitter / Youtube)

This time I will review Domiplan 50mm F2.8.

This review is part 3 of the “Soap Bubble Bokeh” lens.

Part 1: Super-Takumar 105mm F2.8
Part 2: Fujinon 55mm F2.2

And this Domiplan 50mm F2.8 is a lens of the same brand as Torioplan that can create “Soap Bubble Bokeh”.

Domiplan 50mm F2.8 is the same Meyer Optik brand lens as Torioplan

Domiplan 50mm F2.8 was originally manufactured by Meyer Optik. Later, Pentacon in East Germany took over the production.

At the time, this lens had individual differences in state, so the reputation seems to have been controversial.

The inconvenient part of this lens is the spec that the minimum focus distance is 75cm.

On the other hand, it has the same Toriplet type lens configuration as Torioplan and is now popular as a vintage lens for creating “Soap Bubble Bokeh”.

I purchased this Domiplan 50mm F2.8 through ebay.

Select a mount adapter (to use Domiplan 50mm F2.8 with a digital camera)

A mount adapter is required to use the vintage lens with current digital cameras. Domiplan 50mm F2.8 is M42 mount lens.

If you want to use Domiplan 50mm F2.8 with PENTAX digital SLR, you need a mount adapter called M42-PK. It is a thin adapter.

If you use this lens with a SONY mirrorless camera, you will need a mount adapter called M42-NEX.

I’m introducing the mount adapter installation procedure on YouTube video, so please refer to it.

Use a mount adapter suitable for your digital camera.

Photo sample by Domiplan 50mm F2.8

Here are some sample photos taken with the Domiplan 50mm F2.8.

with Domiplan 50mm F2.8 attached to PENTAX K-7

I learned from previous lenses that Soap Bubble Bokeh is prone to occur when there is a light source.

I attached a Domiplan 50mm F2.8 to the SLR PENTAX K-7 and photographed the neighborhood at night.

This lens is frustrating because it is too close to shoot, but the image is not bad.

The outline of “Soap Bubble Bokeh” in this photo taken with this lens is much sharper than that taken with Fujinon.

“Soap Bubble Bokeh” photos by Domiplan 50mm F2.8

Next, I will introduce “Soap Bubble Bokeh” photos that I photographed at various locations using Domiplan 50mm F2.8.

Chidorigafuchi Location


The first two photos were taken at a place called Chidorigafuchi in the spring. Chidorigafuchi is in full bloom during this season. The camera body uses PNETAX K-7.

The above photo was taken in Shibuya. Nikon D750 was used as the camera body.

This is my room. This is where I like the Soap Bubble Bokeh photos. Sony Alpha 7II was used as the camera body.

Domiplan 50mm F2.8 Review Summary

This time, I reviewed Domiplan 50mm F2.8.

This vintage lens is very reasonable and recommended as an alternative to Torioplan that can shoot “Soap Bubble Bokeh”. Although this lens has a weak point with a minimum shooting distance of 75cm, it was a good image for normal shooting.

Thank you for reading to the end.
