Lenstip tested the Kamlan 50mm f/1.1 lens which you can buy at Amazon US, Amazon DE, Amazon UK, Amazon FR, Amazon IT and Amazon ES. This is an APS-C lens and Lenstip texted the X-mount version. But the performance is the same as on the E-mount:

Pros:

• sensible build quality of the barrel,
• good image quality in the frame centre,
• moderate lateral chromatic aberration,
• slight distortion,
• nice appearance of out-of-focus areas,
• affordable price.

Cons:

• very weak image quality on the edge of the frame,
• some spherical aberration problems,
• huge coma,
• distinct vignetting,
• weak performance against bright light,
• some casualness when it comes to aperture markings.

Ok., own up: who was taken in enough to believe that a lens with just 5 elements, an aperture as fast as f/1.1, and costing just $180 will produce excellent images? Realists, who don’t believe in miracles, cannot be surprised by results presented in previous chapters and they won’t be disappointed. I count myself among them so the summary is going to be positive.

Just a short time ago Sony introduced a new range of Global Shutter sensors. We can be certain Sony will use them on their own future Alpha cameras too.

For now the biggest global shutter they announced is a 31.4 MP APS-C sensor in 4:3 format. The first company using it is Lucid Vision Labs. And they shared their preliminary Lab results:

I am not expert enough to give a correct evaluation of those numbers. Might be interesting to read the comments from some of our expert SAR readers!

Marc Alhadeff from SonyAlphaBlog tested the new Meyer Optik Plasmat 105 f/2.7 lens. He had the Nikon mount version and adapted it on the Sony. This is the first and also likely the last review of this lens because Meyer Optik filed for bancrupcy and the lens can be no more preordered:

Based on the prototype I had, I can confirm that The Meyer Optik APO Makro Plasmat 105mm F2.7 has a unique signature 

• At short distance you get this special bokeh
• Aperture closed down, as from F5.6 you get very good sharpness and a nice color rendering that remembers me some analogue films 

So as usual, not a generalist lens , but a lens for vintage lens lover who like it’s bokeh and color rendering

Aaron Edwards posted this introduction video to show the Fotodiox PRONTO Leica M autofocus adapter for Sony E (available here on Amazon).

This is a hot-to video explaining the setup of the Fotodiox Macro Bellows for Sony E:

Voigtlander Color Skopar 21mm f/3.5 E-mount lens at Amazon and BHphoto. In Europe at PCHstore.

Marc Alhadeff tested the new Voigtländer 21mm f/3.5 FE lens:

The Voigltänder 21mm F3.5 Color Skopar (750 Euros) is a very good wide angle lens

Pros

• Compact and light (very discrete)
• Very good  build construction like all Voigtländer,
• Sharpness: very good to excellent
• Low CA , very good resistance to flare
• Reasonable distorsion
• Good Color rendition
• Very good sunstars effect when closed down

Cons

• Heavy lens fall off wide open that never completely disappear
• Background blur can be somewhat nervous depending of the subject
• A little bit lower contrast and sharpness than the excellent Zeiss Loxia 21mm F2.8

The new 24mm f/1.4 GM is in Stock for the very first time via FocusCamera. It should be in Stock within hours here too: Bhphoto. Adorama. Amazon USA. BuyDig. Calumet Germany. WexUK.

Albert Dros posted his full and very detailes 24mm GM lens review. The conclusion in short:

Overall I was very happy with this lens. Most importantly because I didn’t really feel it was even there in my bag because of how small and light weight it was. And I could almost always find a use for it. I would definitely recommend this lens to anyone. I love shooting extreme wide angle and extreme telephoto, but this lens is just so great for a wide variety of uses and it’s always worth it to carry around. Please check the gallery below for lots of more images I took with this lens in Iceland.

Summary:
Very versatile lens
Excellent sharpness on all apertures even wide open at f/1.4
Very lightweight with only 445 grams
Aperture ring on the lens and a switch to make it stepless.
67mm filter thread
Great sunstar
Great for astrophotography. Stars in corners are sharp with very few coma and aberrations. Best performance on such a lens this fast I’ve seen.
Has some flaring going on that is fixed by putting the lens hood most of the times.
Overall a great allrounder prime. to carry around everywhere
