The one on the right is a post-war Trioplan 100mm f/2.8 for comparison:



Got the one on the left today from a local seller. Uncoated, no damage to the glass, some dust inside and focus stiff but in quite good condition.

Serial Nr. 904545, from around WWII
f/2.8 - f/22
~1.2m - 1.25m - 40m - infinity
Exakta
Made out of heavy steel, not aluminium like post-war.

Of course I have some questions. Smile
In the search there are some topics about pre-war Trioplan 10cm f/2.8, is this the same one?

Also, I've got a 39mm lens hood, but it doesn't fit (the hood is a tiny bit too narrow, maybe not even a millimeter). Are there any 40mm-diameter-hoods that you know of? Preferably meant for ~100mm, I couldn't find any on eBay.

The pre-war one should be stunning. I doubt it's steel though, will be chromed brass which to me, always feels much nicer than aluminium.

It's indeed not steel but chromed brass, didn't know the English term for it, thank you. There's some tiny wear with yellow/gold/copper-like underground on the rings.

Although it's maybe nicer to have chromed brass than alu, it's a lot heavier as well, not always something I prefer. Smile

Yes, you can always see a yellowish colour where the chrome has worn with these old lenses, you will see it referred to as 'brassing'.

I don't mind heavy lenses, I find them much easier to control in the longer lengths, less shake.

Nice images. I think the distinguishing quality of this lens is its bokeh. I also recognized the bluish glow that shows up sometimes when using Meyer lenses at wider apertures. As all-around lenses, I find them lacking, but they have their niche.

Really good images and lens.

Very beautiful images!! What is the thing on the bottom of the right side lens? Can it be removed and how to remove it? Thank You Dog

That's a leaver for automatic-aperture using with Exakta cameras (aperture close when you make a shot and pushing this leaver). Quite complicated mechanism these days, and unreliable (according to the fact that this version had 11 iris blades).
Could It be removed? I think yes, but IMO much easier to buy Trioplan with fully mechanical aperture.

Er, chrome plated? Like Dog

The process first undergoes a copper plating, then nickel plating prior to the chromium.
Plating = Electro plating.
