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

First image samples shot with the new Voigtländer NOKTON 50mm f/1.0 Aspherical E-mount lens

Voigtlander at BHphoto and in Europe at FotoErhardt, Calumet, Fotokoch.

Mapcamera had the unique chance to play with the new Voigtländer NOKTON 50mm f/1.0 Aspherical E-mount lens. These images have been taken with the lens on the Sony A7rV and the author writes:

The color is really neutral and reproduces what you see. Up to F1.2, the image has a very soft and warm expression, and as you stop down from F1.4, the focus area gradually tightens, giving you a sense of transparency. I really felt that this lens taught me how fun it was to manipulate.

It’s been a long time since I came across a lens that really made me feel the joy of controlling the aperture. This looks like it will become an indispensable lens for cityscape snapshots.

Some more image samples also on this second Mapcamera report.

Personal note: I am considering to buy this lens!!!
