Sony 24mm f/1.4 GM lens at Bhphoto. Adorama. Amazon. Calumet Germany. WexUK.

Marc Alhadeff tested the new Sony 24mm GM lens. This is his conclusion:

The Sony 24mm F1.4 GM is a new masterpiece from Sony and well deserve its GM label. It is certainly one of the best 24mm if we consider all criteria together

• Excellent sharpness wide open across the full field, even wide open (Note : for close distance corners are “only” very good at F1.4/F2)
• Fast and accurate AF with very good Eye AF performance
• Small and light
• Excellent bokeh and very smooth background blur 
• Fast Aperture : F1.4 : perfect for low light 
• Very small focusing distance + F1.4 = perfect for small depth of field
• Very good contrast and 3D effect at F1.4 for people portraits
• No field curvature
• Very low distorsion
• Very low coma (suited for Astrophotography)
• Suited for video thanks to click less aperture ring
• Very good color rendition (but Zeiss Loxia 25mm F2.4 is excellent)
• Very well built, weather sealed

There are however a few area where it is not “perfect”

• Very small amount of CA
• Resistance to flare is good but not excellent
• Vignetting at F1.4 & F2 (a future Lightroom Lens profile will correct it)
• Price (but in line with GM price range)

The lens is very versatile and will be the perfect choice for landscape, street photography, , low light, architecture, people reportage, full body portraits, astrophotography, and this  both in photo and in video

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

Photographyblog tested the new Voigtlander FE lens and the conclusion is:

The super-compact and very lightweight Voigtlander 21mm F3.5 Color-Skopar is an excellent wide-angle prime lens that delivers great image quality. Shooting at the maximum f/3.5 aperture does reveal a very minor reduction in sharpness in the centre of the frame, but this is quickly resolved by stopping down to f/4. The edges aren’t quite so sharp, though, with f/8-f/16 producing the best results.

In addition to the edge sharpness, there are a couple of other image quality drawbacks to the Voigtlander 21mm F3.5 Color-Skopar. Vignetting is obvious wide-open at f/3.5, and still fairly evident at f/5.6, although in real-world use it’s less of a problem than when photographing a white wall/test-chart. The lens also suffered from some rather obvious purple and green fringing in high-contrast shots. The Voigtlander 21mm F3.5 Color-Skopar does deliver nice sun-stars though thanks to its ten-blade aperture.

The Voigtlander 21mm F3.5 Color-Skopar is a veritable pleasure to use, thanks to its superb build quality, smooth focus ring and tactile aperture ring. As this is a manual-focus only lens, you’d expect this aspect of the operation to be intuitive, and so it proved. Together with the A7R II’s excellent Peaking and Manual Focus Assist features, the Voigtlander 21mm F3.5 Color-Skopar delivered a very high percentage of keepers. The 20cm minimum focusing distance also makes the lens surprisingly versatile when shooting close subjects.

We did miss having a de-clickable aperture ring, though, which recent Voigtlander lenses designed from the ground-up for the Sony FE system have offered, making this lens less suitable for video use.

In summary, the Voigtlander Nokton Classic 35mm F1.4 is a very compact, extremely well-built and affordable wide-angle prime lens for full-frame E-Mount Sony owners. Highly Recommended!
