Voigtlander Color-Skopar 20mm f/3.5 SL - first impressions

Hi! I just received my new Voigtlander Color Skopar 20mm F3.5 SLII Aspherical lens in Nikon AIS mount today from Steve Gandy at Camera Quest. I opened up the box, played with the lens a bit, put it on my D300 and shot a few small jpgs outside (it's cold, gray and cloudy today here in Wisconsin USA). Below are my intial impressions. Over the weekend, I'd be happy to shoot a few more photos and post some further updates if you'd like.
1. I could not believe how small and lightweight the lens is (only 200 grams). My Zeiss ZF 35mm F/2 at 600mm seems huge compared to this tiny lens. My first words upon taking it out of the box were - "Is that all there is to it"? It's by far the smallest lens I've ever owned. If you are looking for something lightweight in this focal length to pack light, this is the lens for you.
2. The Voightlander front lens cap is pretty cheap and flimsy. I will replace it with one of my 52mm Nikon caps.
3. It was harder to mount this lens onto my D300 than any other lens I've ever owned. Actually, I like that. It definitely gave me the impression that it fits really tightly onto my camera body. I suspect this "tightness" might be advantageous at keeping dust out and maintaining proper lens alignment.
4. The focusing ring is firm, with a similar precision feel as the Zeiss ZF 35mm F/2. It takes 180 degrees to rotate the ring from infinity to 20 centimeters - not an issue one way or the other to me as I will almost always use it prefocusing using hyper focus.
5. The aperture clicks in whole stops between 3.5 and 22. Nothing special here, similar to most of the manual Nikkors I've owned (e.g. 20mm F2.8 AIS, 24mm F2.8 AIS, 28mm F2 AIS, 28mm F2.8 AIS, 28mm F3.5 non Ai).
6. Overall mechanical impression - good. Not quite up to the Zeiss ZF standards, and on a par with a new Nikkor AIS wide prime lens (which is very very good).
7. The image you see in your viewfinder is not very bright. Buy I guess that's a function of it being a F3.5 lens.
8. One Japanese reviewer commented that this lens has some barrel distortion. It did not notice any unacceptable level of barrel distortion, but I shoot landscapes, not architecture.
9. The colors right out of the camera I'd describe as vivid, yet natural. By my eye, I like the colors better than my nikkors or the Zeiss ZF 35mm.
10. I could see no visible CA. This is a big deal to me! The Zeiss 35mm ZF F/2 had so much purple fringing at high contrast edges that I sold the lens a few months ago. I've never had any significant trouble with CA on any of the Nikkor wides primes I've owned, or with the Nikkor 17 - 35mm F/2.8 zooms I've owned (2).
11. The shaddow detail seems pretty good.
12. Seems much sharper in the corners than the Nikkor 20mm F2.8 AIS.
13. One characteristic that is very important to me (that I hope to check out this weekend) is sharpness of the lens both near and far (at infinity) when stopped down to F8, F11, and F16. I was blown away by the close sharpness of the Nikkor 28mm F2.8 AIS, but it was not that sharp at infinity. If this lens is sharp up close AND at infinity, I've got a keeper here.
More to come...
