I'm seeing some strange bokeh, and some good bokeh.

Nice colors. I think this lens is supposed to be practically identical to the Contax Planar 501.7, which is known for it's bokeh that can get quite crazy wide open. The Planar 50/1.4 does the same thing (Contax and Zeiss Z*).

HFT is the Zeiss coating used on Rollei lenses that were made by Zeiss. In my experience, if it doesn't say HFT on the lens (or VMC, SMC, T*, or whatever), then it's not HFT.

I've compared the Contax Carl Zeiss Distagon T* 35mm f/2.8, Rollei Distagon 35/2.8 HFT, and Voigtlander Color Skoparex 35/2.8 AR. The Contaz Zeiss was much better than both QBM lenses (even the Rollei made by Zeiss), and so I stick with Contax Zeiss, rather than further exploring the Rollei 35mm QBM lenses. OTOH, the modern Voigtlander SL and SL II lenses are very nice, and so are Leica-R, but they're getting a bit spendy.

Could be one of 3 lens designs. A true Ultron with a concave front element, a modified ultron with a slightly convex front element and still 7 elements in 6 groups or a simplified planar design of 6 elements in 4 groups.

The Contax 50/1.7 is a Planar design with an extra element in the rear group, whereas the Ultron design has an extra element in the front group.

Aside from both being double-gauss in essence, they are quite different lenses and I'd say they're as similar as an Olympus 55/1.2 and a Noct-Nikkor 58/1.2 ... that is to say, apples and oranges in the world of 50's.

EDIT:

Had a look at the link to pictures of the lens, and it is definitely the modified ultron design.

Whereas this is the Contax 50/1.7 Planar:

Many thanks to both of you for the information!
Very good to know.
Corrected WB of the bokeh difference of this lens:

Something is amiss w/ the forums?
I could not see the following post when I am logged in.
Not being logged in, I can see it.
Strange...

Anywho, I'd like to add the comment that I got this lens for $125.00
BNIB, or NOS, however you wish to look at it.
I think I'll keep it.

Another thing I should have mentioned from day one is,
this does NOT infinity focus on my 5DMkII.

I would watch out with that. On the mflenses forum someone managed to crash his 5DmkII's mirror into the lens, actually damaging the glass of the mirror. I don't know what he exactly did, but it doesn't sound nice.

Wow! Thanks for the warning!
I can actually feel it when adjusting the focal length to infinity, right at the end, it feels like it is coming into contact w/ something.
When I felt this, I knew not to try and take a pic.
Yes, as I said, I should have stated this from the start.
It works okay on the 40D, and I guess, any other 1.6 crop body.

Found the page again: http://forum.mflenses.com/i-shaved-my-5ds-mirror-t5471,start,45.html#198084

Edit: That was not exactly the same lens as discussed here. I think it was a Rollei mount lens though (Zeiss 50/1.4 HFT).

Following the same source the later Color-Ultrons made in Singapore have a six lenses design, not 7 lenses.
