One other note, if you are going to adapt C/Y lenses, to get their best performance, you need to flock your adapters (all metal adapter need flocking) and maybe shimming (or at least buying and testing multiple adapters).

You're welcome
Maybe the Minolta MD 4/200 could do it for you if you remove the chromatic aberrations in the postprocessing.
Thanks! I have heard about that lens. I don't mind CA. Haven't seen any on eBay, but I'll keep my eyes peeled!
EDIT: Just purchased one!

Getting an adapter with close to perfect mount-to-mount parallelism is no easy task. From my experience, the popular Metabones is not the best option. I have had great luck with Novoflex and Kipon with adapted lenses. This is crucial with wide and ultra wide lenses. I agree that flocking is a must to avoid unwanted reflections.
@Jannik Peters, Thanks for the tip on the 100/3.5, I will definitely try it out. Something I am curious about is the shape of the 35-70/3.4 sunstar and how resistant it is to flare. Apparently it only has 7 aperture blades.

Mine has got 8
This sample should be exemplary for both - flare and sun star. I pushed clarity to 41 and pulled the lights down to -100 to visualize both things.
Sun stars are pretty odd, but better than with the 3.5/100. I think this was f/8.

Thanks Jannik,
Contrast looks great and there is minor flare on this sample. The 8-point sunstar could be interesting at smaller apertures.

I think you need to try again on the sunstar. This image has a lot of haze to it and I doubt it is a good reflection of sunstar potential. Just a thought.

Bob, do you have some samples showcasing the sunstar?

Not yet, Fred. I just got my lens and took one shot that included the sun in hazy weather. I was stopped down to F/11 and hardly got anything so I deleted the image. The result was similar to other lenses that give good sunstars but when shooting into hazy conditions, it's harder to achieve more than a blown out blob. I'll try to get something tonight.

I bet you are right, Bob. It is funny that I don't have more images with sun stars from that lens.

I will try shooting the sun with the Contax and compare it to the 24-70GM's. (Which initially didn't give me pleasant results)
Here in San Clemente is pretty clear right now. Where is my adapter!!!

I've got some examples from sunset on the tops of mountains in Norway. I'll post it after work.

Fred...Here is a sunstar with the 35-70. As I shoot into the sun a lot, I made sure this would work for me!
And mine has 8 blades too
I also was telling Bob about the Raqual C/Y adapter. It's baffled, and I get perfect infinty focus too
Gregg
I think I stopped down to f16 on this..
another with my old A7

Here's a couple from me from this morning. The light source also determines how sharp the star will be. In this case, the street light is not a pinpoint light source so the sunstar is broader. In the second scene, you can see a better sunstar in the lower right of the image based on a better pinpoint of light.

Thank's, Bob 
I still prefer the sharp Loxia sun star, but the 3.4/35-70-star is at least better compared to the one of the Sonnar 3.5/100. I would rate it "average".

I would tend to agree. My favs are Loxia and Voigtlander sunstars.

It's definitely not a very pretty sunburst, IMO. IDK how Greg got a daytime star, I could not get mine to make one against a more clear sky yesterday...

I agree with the Loxia/CV sunburst. They are clean/sharp with similar shape complemented by strong flare resistance and 10 blade aperture. I don't like the look of the 24-70/2.8GM sunstar either and flare is a bigger problem. It could be that even though the 35-70/3.4 is not optimum on this area, it's still could be better than the GM zoom.
