*CameraQuest has the CV 21/3.5 E-mount in-stock right now!
___________________
Voigtlander-Cosina Japan just announced their new Color Skopar 21mm f/3.5 E-mount lens. It’s priced at ¥ 85,000 and will start shipping in October.
This thread will be updated with the USA pre-order information. Price is expected to be $799 but not yet confirmed.
As with other Voigtlander E-mount lenses, electronic contact transmit EXIF information of the shooting data. In addition, because it incorporates a distance encoder, it supports 5-axis camera shake correction on the camera body side. It is also possible to enlarge the viewfinder by operating the focus ring.
In addition to securing full-size image circle, it adopts optical design optimized for Sony E mount sensor. High resolution is maintained up to the periphery of the screen, and phenomena such as color hue are suppressed. Its optical design consists of 9 Elements in 8 groups. (One aspherical surface + an anomalous partial dispersion element)
By adopting a total metal helicoid unit machined and adjusted with high accuracy and high quality grease producing moderate torque, smooth operation feeling is realized. It enables delicate focus adjustment.
The minimum focus distance is 20 cm allowing an unique ultra wide angle perspective and the lens only weighs 230 grams.
Main specifications:
Focal length: 21 mm
Maximum Aperture: F3.5
Minimum aperture: F22
Lens configuration: 8 groups / 9 Elements
One aspherical surface + an anomalous partial dispersion element
This should be a fun lens to be looking at for sure. I would not mind having one myself. I’m 15,25 right now but a 21 would not hurt me at all. Like it more a 20 so have to see the actual focal length.
For a travel kit in CV only one could go 15,21,40or 50 and either the CV 65 or a small 85. This adds another option to build on
CV has made a similar lens before in Nikon F Mount. It was a wellmade, compact but not particularly Hi IQ lens. Therefore I will wait for Fred’s tests to see if this version of the mount is superior.
Note however, that CV makes a well made 40mm F2.0 pancake lens of better quality. Even with an adaptor it is a handy MF combo

The Voigtländer 21/3.5 FE seems more similar to the Voigtländer 21/4 VM than to the 20/3.5 SL-II, but there are clear differences as well.
Hopefully the design is not as challenging as the 15 with regards to copy variation. Either way, it adds to the embarrassment of riches for WA on the e-mount.

From my experience, only the CV 15 has high copy variance. Other Voigtlanders, including the ultra wides 10mm and 12mm, do not suffer from that. Like you wrote, I agree that the CV 15's optical design may be challenging to produce with consistency.

I had the CV 20/3.5 SLR lens and it was a rather compromised design, certainly at wider apertures, but was so lightweight and small that it was a lens I actually took places and often left the 16-35 at home.
Given the other wide angle Voigtlanders in E-mount I think it's a fair bet that the optics of the new lens will be a substantial improvement over the SLR lens. And considering the popularity of the Loxia 21 (and Batis and Loxia 25s and Tokina 20/2) the competition is hot and I can't see Voigtlander hoping to sell anything other than a very good lens. The price and size perhaps suggest it won't quite be on the level of the Loxia but it is considerably smaller; if it can get anywhere near the Loxia then it could be a big success especially when one considers that as a landscape lens it is most likely to be used at f/5.6-f/11.
I could imagine this forming part of some lightweight kits - perhaps this CV 21/3.5, the Sony-Zeiss 55/1.8 and the Sony G 70-300 as a kit that one could hike with but still shoot wide angle landscapes, portraits and wildlife with.

By looking at the lens' picture, it does not look like the CV 21/3.5 has a de-clicking ring. I could be wrong though.
It’s not impossible that this could equal the Lox by, say, f4.5. If it does I could be tempted to downgrade for hiking purposes. I pretty much only used the Lox at f2.8 when testing it. For thinner DOF work I prefer a 24...

They are saying it's sharp to the edges.
It may be very popular if it matches the Loxia by f/5.6 (resolution/contrast) and has similar CA/Flare control.
If it has lower field curvature, even better.

If I'm not mistaken, the original specs mentioned a de-click feature, is that still the plan?
*EDIT* it's not mentioned in that release, but the white dot is visible in the pic. Hopefully that means yes.
I don't think it will have that de-click feature.The Nokton classic 35/1.4 E-mount lens has same kind of white dot as aperture marker but there is no de-click feature on that one. The bodies of 21/3.5 and 35/1.4 look very similar in size and style.
Cosina has also described the de-click mechanism on the description of all of those lenses that have it on their web-site, but no description for 21/3.5 nor 35/1.4.
I don't think that the de-click feature was mentioned at the original specs shown at CP+ either. I looked up the Japanese pdf (http://www.cosina.co.jp/cp2018/CP2018%20.pdf) and it is not mentioned there.

Ah, gotcha. Not a deal-breaker, but kinda a bummer.

I have a fantastic copy of the Loxia, but I'd happily replace it for this if it offered "close enough" image quality at smaller apertures. Very rarely do I use the Lox wide open.
