Looks good 👏 Do the two shades of silver match well, or is there actually a noticeable difference in reality? Quote Link to post Share on other sites More sharing options...

gammarART Posted January 29 Share #83 Posted January 29 (edited) With the high-end SL lenses, I find those massive lens hoods absolutely hideous. But this one on the 90mm Ultron actually feels kind of fitting. Edited January 29 by gammarART Quote Link to post Share on other sites More sharing options...

First I have a question about vignetting: Did you notice a difference between your hood and the original hood and the recording without the hood? I'm asking for the following reason: I've noticed here and there that the replacement clip-on lenses often cause stronger vignetting. One more question: Have you noticed whether anything has changed when taking photos - stray light or shots in semi-backlight? I'm sorry, I find the hood pictured a lit bit monstrous. I also have the feeling that the silver lens on the silver camera also looks considerably larger than the black lens on a black camera. But in the end it is a matter of personal taste.

J S H Posted January 29 Share #85 Posted January 29 3 hours ago, lct said: What brand is this hood if i may ask? That is an older Pentax hood. I have several of them from 49-82mm size and they are great. Very well designed - they easily clip onto the lens or filter and they can often clip on in reverse orientation as well. They can be hard to find and it's sometimes a guessing game as to how well they might work for any given lens. I often use them for studio shoots so that I can easily identify the degree of polarization when I shift from V to H. Set the desired amount of polarization to match up with the aligned flat edge of the hood and just rotate the hood 90 degrees when you rotate the camera. 3 1 Quote Link to post Share on other sites More sharing options...

Using of lens hood to avoid of light flare in semi-backlight condition is strongly recommended. The outer diameter of this rectangular lens hood is almost the same as the original lens hood, no vignetting effect is caused by this clip-on lens hood. The temperature of the silver barrel of lens is lower than those in black color at hot weather photographic condition. Quote Link to post Share on other sites More sharing options...

And, of course, an "APO" marketing designation these days doesn't even have that much to do with the correction of longitudinal chromatic aberration - even for Leica. [--] Cosina is just clarifying that their APO designation is the science-based one. APO relates to axial CA only. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! I noted this lateral/transverse CA in my Elmarit 21mm /E60. And also in my new LLL 28mm/9E, but about the half of the Elmarit. I saw picture @pegelli made with a 75mm Lux and that also showed this effect on the edge of the frame (camera straps doubled). Small things like branches get a life of their own. As such annoying. But I once had the SA 21 and gave that back because of the corners - like this. Too bad. However I like the rendering of the old Elmarit (Mandler..) so no complaints. Quote Link to post Share on other sites More sharing options...

I’m asking because the shot with the 90mm f/2.8 Apo Skopar would definitely have had a magenta tint. I’d appreciate it if the new Ultron renders colors differently in that regard.

The color of the images have been adjusted by adding tiny cyan in order to decrease a red tint, a little amount of glow in the high-light area of the images with creamy bokeh is very nice, indeed.

adan Posted February 4 Share #96 Posted February 4 It is an announced feature of the two recent Voigtlander 90s that the 12-blade aperture remains circular, and not a polygon, wide-open and stopped down one or two stops. And also at the smallest aperture. Whether those apertures produce "cats-eyes" bokeh is a function of vignetting - a separate question. 12-blade aperture diaphragm for beautiful bokeh The 12 blade aperture diaphragm produces an aperture opening as circular as possible. Out-of-focus areas of images are drawn naturally and point light sources etc. are drawn as soft round bokeh rather than as polygonal shapes. https://shop.cameraquest.com/voigtlander-leica-mount-lenses/voigtlander-90mm-f2.0-black-apo-ultron-m/ 1 Quote Link to post Share on other sites More sharing options...
takar Posted February 26 Share #97 Posted February 26 I bought a brand new black version. I noticed a strange aberration of this lens when I was shooting far away landscapes with Leica SL2-S and Leica M adapter L. When I focused on the upper right corner, the buildings in the upper left corner, which should have been almost equidistant from the lens, appeared very fuzzy. Furthermore, the building in the foreground, which should have been within the depth of field, also appeared blurred, which made me think that the field curvature was large Welcome, dear visitor!

takar Posted February 26 Share #98 Posted February 26 Of course, I understand that my shooting conditions are not appropriate. On the other hand, the sigma 28-105mm f/2.8 DG DN corrected the image very well, so I think it is unlikely that there was a problem with the shooting environment. Welcome, dear visitor!

takar Posted February 26 Share #99 Posted February 26 A similar phenomenon occurs with the APO-SUMMICRON M 90mm ASPH, but it is not as bad as with the APO-ULTRON. The focus is set to the upper left corner, so I am looking at the edge in the lower right corner. The exposure was slightly adjusted because it was taken with EOS R5 on a different day.

Are you sure they are equidistant? You chose a wide aperture apparently (f/2?). On a 90mm lens, DoF can be shallow with apertures that wide.
