It has been a good week for the few Sony fans amongst us, both Voigtlander and Zeiss announced their wide angle lenses for the a7 platform.
The totally new Voigtlander 10/5.6 which will also be available in VM mount for the Leica M fans or those with other mirrorless systems

The Voigtlander 12/5.6 & 15/4.5, the former will also be updated in the VM mount and the latter is already updated in VM mount

The Zeiss Loxia 21/2.8, exclusive for the Sony E mount

Exciting times :)
-
The Loxia and the Milvus are both MF 2.8/21mm for Sony?
How to they differ?
Is there an AF option too?
-
Selfies with this 10 mm lens would be something .... :D
130 degrees field of coverage. I wonder what the vignetting will be into the corners - 5 stops?
Anyway, the appearance of these wide angle lenses surely will add to the Sony E appeal for many potential buyers.
-
Good news for Sony fans and too bad I am not one of them. But the Zeiss Milvuses for Nikon are coming! If they are as good as the Zeiss 135mm Apo zf.2 lens, that is very promising.

Completely different lenses, the Milvus lineup is for Nikon and Canon DLSR cameras and the Loxia lineup is dedicated for the Sony E mount with most lenses based on their Leica M variants so the designs are mirrorless from the start. The Loxia is a lot smaller and weighs roughly half the weight of the Milvus counterpart.
This the first 21mm for the a7 series and manual focus only, its fully modernised however so EXIF, focus distance, aperture, etc are communicated to the camera.
-
A few months back I tried Eriks 12/5.6 on the a7S which worked pretty good so a modernised version is very appealing.
Never shot a full frame 10mm so I have no idea what to expect besides making sure that my feet are not in each frame ;D
I'm a big fan of ultra wide lenses so I can't wait to get my hands on these lenses.

Jan Anne,
That one looks great! Could you post more A7 shots? I've always liked the size of the camera but two things were holding me back: lack of AF lenses and the output. Most photos I saw looked "digital" (sorry but can't find a better word) but yours looks very natural. So is it just a matter of overprocessing of others?
-
Peter, sometimes overcooking the images is plain fun ;D
Here's one from last Saturday with the original Voigtlander 15/4.5 in Leica Threaded Mount

Review of the Loxia 21/2.8:

-
It is a little confusing but
12mm f/5.6 is a new optical formula Mark III - the Mark II was already in Leica M mount
the 15mm is already a Mark III in Leica M
:D
-
I thought that rangefinder lenses did not agree with the digital sensor due to the acute angle of the light. Has this been reduced?
-
The original a7R was notoriously bad with wide angle Leica M lenses, especially those from the film era, my a7S is a lot more forgiving though.
For instance this is the 15/4.5 LTM on the a7R, lots vignetting and color shifts (sorry no color image online at the moment):
(https://c2.staticflickr.com/8/7449/11032063135_67a0e36517_b.jpg)
These newly introduced lenses are completely redesigned for digital, for instance 15/4.5 MKIII has grown significantly to cope with the corners.
Here's my uber tiny LTM version, at 109 grams its so cute :D
(https://c1.staticflickr.com/3/2838/11011639603_cc43ce0f01_c.jpg)
Now compare that to the MKIII which is more than twice the weight and size:

As for 12/5.6, neither Sonyalpharumours or dpreview news states clearly that it is "re-dedigned". Sonyalpharumours says that the lens design is "based on" the current M-mount version and is "optimized" for the digital camera on the E-version. I don't know how to differentiate "redesign" from "optimize".

Voigtlander has this to say:
VM-Mount
Voigtländer continues its VM-Mount digital optimization with the new 12 mm F 5,6 Ultra-Wide-Heliar III. Additionally Voigtländer will also release the new 10 mm F 5,6 Hyper-Wide-Heliar with VM-Mount.

Apparently the glass of 12/5.6 is not redesigned. Optimization seems to mean the barrel is designed so that the lens can communicate with the cameras.
-
We'll see, btw I read this
Voigtländer continues its VM-Mount digital optimization with the new 12 mm F 5,6 Ultra-Wide-Heliar III
as they will give the 12/5.6 the same treatment as the 15/4.5 which was completely redesigned with a totally different optical design.
Anyhow, great news that will be bringing back these babies optimised for the Leica and mirrorless platforms ;D

The Loxia 21mm is all new design,
related only broadly to the old film-intended Biogon ZM.
Update: Zeiss says it's a Distagon = retrofocus in Zeiss-speak.
Hopefully this means that a relatively distortion-free 21mm is now available for 24x36. The distortion chart for the Loxia shows a fair amount of barrel, but not as severely mustached as the ZF/ZE Distagon 21.
The Milvus 21mm appears** to be the same optical design as the previous ZF/ZE 21mm, but with a new barrel housing. Hello, mustache distortion...I know thee well.
**Based on the visual cross-section illustration in the Zeiss data sheet.
-

It definitely is according to Zeiss. They improved the surface coating of the lenses inside, but the optical design stayed the same.
Same for all other Milvus lenses apart from the new Milvus 50 mm 1.4 and Milvus 85 mm 1.4

Meyer Optiks announced another new entry into the Sony E-Mount: a 0.95/35mm "NOCTURNUS": http://www.meyer-optik-goerlitz.com/nocturnus-f095-35mm/

This is for APS-C format and is destined to be immediately rejected by Jan. :D
-
Probably right about Jan but at 2000 Euros I can easily reject it ;) . That almost exactly the price of Batis 25 and 85 from my dealer :( and considerably more than the Zeiss 135 APO ZF.2 that I periodically think about.

I disagree.
It is a new optical design of the the 12mm, optimized for digital, similar to what they did to the 15mm from Mark II to III.
-

Exactly, not that I'm against the APS-C format but currently I only have the a7S with a "measly" 12MP full frame sensor so using lenses in crop mode makes little sense.
Should be an awesome lens however for those with smaller format mirrorless cameras, if the 2K price tag isn't an issue of course like Tommy mentioned.

APC-C? What a stupid... Did not see it.

Thanks Erik for those specs, good to know that they've come up with a completely different design for digital.

Steve took a look at the Loxia 21/2.8 FE on the a7RII:
