Thanks, Juha. Appreciate the new close-distance samples. Added them to the review links. I suppose we're among the few who have this lens on hand since it's not available in the US yet.
While my current Voigtlander 18mm f/2.8 Color Skopar is well-centered, I plan to acquire a second copy soon to double-check its resolution and contrast capabilities. I typically test multiple copies to ensure that my review accurately reflects the lens's performance.
Meanwhile, here are a few additional samples taken in low light conditions:
P.S.: You might observe that in the last sample, sunstars can be captured even when shooting with the aperture wide open!

New here (have been a lurker on and off for years). Any word when these are supposed to be available at Camera Quest? I have the 27mm and can't wait to add this 18mm, 18 being my most used focal length. The images here look great!
Coma is visible when shooting with the Voigtlander 18mm f/2.8 Ultron lens wide open at f/2.8, but it's significantly reduced at f/3.2 and f/4. Although it's a wide-angle lens and can be used for nightscapes, the somewhat slow f/2.8 aperture is not the best choice for this application. However, it can still be used with the help of noise reduction in post-processing. In normal usage, coma is not very noticeable in the out-of-focus rendering.
Below, you'll find 100% crops showcasing a bright star positioned near the edge of the frame. The images were captured incrementally at 1-stop intervals, starting from the widest aperture of f/2.8.

CameraQuest is showing them says "out of stock" with a price of $0. Soon, perhaps?
I got the word that it will be available for sale tomorrow at Cameraquest.
The Voigtlander 18mm f/2.8 Color-Skopar has a field curvature shape that varies depending on the focused distance. When focused up close, the curvature seems to extend outward, while at medium distances, it becomes flatter. At longer distances beyond 5m, the curvature shifts inward, similar to the 27mm f/2 Ultron. This typically results in better out-of-focus rendering towards the corners of the frame, and also makes it a preferred field curvature shape for shooting landscapes where the distance center and foreground sides appear sharper.
To demonstrate this effect, I've processed a sequence using the "find edges" technique. The sequence shows how the lens behaves as it's focused from 1m to a point far into the distance, approaching infinity, in a GIF animation.

Nice samples Fred. Looking at all your samples I may be wrong but the ~28mm FOV suits your style nicely.
Too bad the new Fujifilm X100VI doesn't have a 28mm equivalent with a slight crop to 35mm. I know I would
like that more myself.
Thank you! I do enjoy shooting 28mm. The Voigtlander 18/2.8 Color-Skopar is a great alternative to the GR series, especially when pair with the super compact X-E4.
Lateral chromatic aberration is effectively corrected, but there are still hints of color error towards the edges of the frame regardless of the aperture setting. This correction is slightly inferior compared to the Voigtlander 27mm f/2 Ultron, which shows no lateral chromatic aberration. It's curious that even after applying the Lightroom correction, I still see some color error.

The lack of purple fringing and axial (longitudinal) chromatic aberration is a remarkable feature of this pancake lens. While I expected very good color error correction because of its f/2.8 aperture, I was pleasantly surprised by the almost APO lens-like correction of axial chromatic aberration.
Even when shooting in bright, high-contrast conditions, I don't see any purple fringing or axial chromatic aberration. This is undoubtedly a strength of this lens, particularly considering that wide-angle lenses typically struggle in this regard, regardless of their size.
The out-of-focus areas behind the focal plane do not exhibit any green outlining. Overall, this lens delivers an impressive performance.
Below are a few samples demonstrating its performance under intense, high-contrast lighting.
All wide open:
Highly reflective metallic surfaces. There is no purple fringing in the focused area, and there is no green color error behind the focused area.

Nice work! The landscape shots you've posted so far look phenomenal! Hard to ask for more from such a tiny lens...there's so much it can do so well already.
Rendering in photography is the subjective aspect that defines how various characteristics like optical vignetting, spherical aberration, highlight outlining, and transition zones contribute to the final appearance of an image.
The Voigtlander 18mm f/2.8 Color-Skopar lens offers a full frame equivalent focal length of 28mm and a depth of field of f/4, resulting in minimal blur unless you're shooting very close, less than 1m away. At close distances, it delivers a distinct rendering compared to modern lenses prioritizing smooth background blur. Shooting wide open and up close may reveal a slight outlining effect in specular highlights, enhancing the overall image structure.
Focusing at its closest distance of 0.17m produces an extremely smooth transition zone and well-controlled outlining due to strong blur, resulting in a pleasingly smooth look. From around 0.7m to 2m, you'll notice the outlining effect, adding character to the image. This characteristic persists when focusing at medium and long distances, although the blur is less pronounced, similar to an f/4 lens on a full frame.
It's worth mentioning that the Voigtlander 18mm f/2.8 Color-Skopar lens effectively minimizes optical vignetting, reducing distortion of specular highlights and avoiding the "cat's-eye" shape. Additionally, it corrects spherical aberration, leading to improved resolution and contrast, even at close distances, with minimal halo or glow effects.
I appreciate the unique rendering capabilities of this lens, offering a refreshing style of its own.
