Some images of the upcoming Viltrox 135mm f/1.8 FE AF lens on the Sony A7cR

At the NABshow Viltrox displayed the 135mm f/1.8 FE autofocus lens. They still did not disclose the exact release date and pricing of the lens. But here you can see the lens mounted on the Sony A7cR.

You can see the LED display and all manual controls. Looks like a solid build. We will have to see if the image quality will match the one of the Sony 135mm GM.

One more thing: The Viltrox 30-300 mm t/4.0 costs $65,000, but you get this additional giant pillow for free:)

Sigma 500mm FE lens review by SonyAlphaBlog: “provides ultimate image quality in a light and small form factor”

500mm f/5.6 at BHphoto, Amazon, Adorama, FotoErhardt, Calumet, WexUK.

SonyAlphaBlog tested the Sigma 500mm lens and concluded:

The Sigma 500mm F5.6 DG DN Sports (3200 euros) is an excellent lens and a very good news for animal shooters. It provides the ultimate image quality in a light and small form factor, much more usable than a 500mm F4 or 400mm f2.8 or the big telephoto zooms at a very reasonable price of 3200 euros. It can fit in a standard backpack

It AF, optical stabilisation , ergonomics, build quality is excellent. Bokeh , color rendition , distortion, Resistance to flare , level of CA are also excellent
The only weak point is the very long min focusing distance of 3.2m and the limitations imposed by Sony : max 15fps and no TC allowed

Highly recommended

New Viltrox 27mm f/1.2 Pro lens reviews

The lens is available at Amazon and BHphoto.

SonyAlphaBlog concluded:

The Viltrox 27mm F1.2 (600 euros) is another gem from Viltrox. Its unusual focal length (40mm equivalent) is a bit narrower than a 23mm (=35mm equivalent). It offers Excellent sharpness, bokeh balls , soft background blur , very good color rendition and very good AF. Note with the F1.2 aperture you will need sometimes to have a ND filter with the limitation of 1/4000 sec on A6xxx
Compared to the Sigma 23mm F1.4 DC DN, it is better balanced as the Sigma although a bit more sharper has more nervous background blur and more Chromatic aberrations
