What stands out is that the Sigma has an exceptional amount of contrast which gives it an advantage in the center and the real-world result. The Samyang is slightly better in the corners in my comparison. Quand on ferme , dès F2 on voit les 9 lames du diaphragme et dans certaines occasions des franges sur les bords Très bon résultats en vidéo avec un très bon piqué , un très beau bokeh et flou d’arrière plan et un très bon rendu des couleurs

We're very easy to find, our London store is just off Oxford Street between Oxford Circus station and Tottenham Court Road station. The Essex shop is located in High Chelmer Shopping Centre, just off the High Street in Chelmsford.The Stevenage shop is located in the Old Town, in the old Post Office with parking outside The focus ring has just the right resistance. Samyang/Rokinon really killed it with this one and I can't wait until their next AF lens for Sony!

Introduction

The 85mm captures quite a bit of light, though, and covers full-frame image sensors, so it's a little big for a prime. It measures 3.9 by 3.5 inches (HD), weighs 1.3 pounds, and supports 77mm front filters. A reversible lens hood, the only plastic component, is included, along with a carrying pouch and the standard front and rear caps. La qualité de construction du Sigma 85mm F1.4 DG DN Art fait jeu égal avec le Sony FE85mm F1.4 GM et est au dessus des Samyang et Sony FE85mm F1.8 We look forward to testing a sample of this lens, as our experiences with the recent Samyang AF 50mm F1.4 FE II and AF 35mm F1.4 FE II were both very positive.

Vignette becomes very mild by F2 and essentially gone by F2.8. This is actually quite a good performance for a wide aperture 85mm lens. Lenses like the Zeiss Otus or Milvus 85mm lenses show very heavy vignette at wide apertures. Le Sigma 85mm F1.4 DG DN Art est le pire en terme de distorsion et de vignettage , le Samyang est au milieu, le meilleur étant le Sony GM Falloff of illumination towards the corners is typical of a fast aperture lens like this. The corners are 2.28 stops darker than the image centre at f/1.4 and visually uniform illumination is achieved by f/5.6. The sharpness is very good wide open and excellent as of F2 and skin rendering is very good but maybe a bit too contrasty sometimesnot corrected corrected F1.4 CA /AC F1.4 crop 100% CA / AC LoCA / AC longitudinales crop 100% F16.
