4.6 Video

Thanks to its focusing ring than can be turned into aperture ring the Samyang 50mm F1.4 II has ergonomics very suited for video and if we add on top its minimal focus breathing it is one of the best in video

The Sony 50mm F1.4 GM is also excellent but show a bit more focus breathing but with better ergonomics and image quality

The Sigma 50mm f1.4 DG DN has very good results and ergonomics but has an important focus breathing

The Viltrox is one of the best in term of ergonomics and no focus breathing

Grâce à sa bague de mise au point qui peut être commutée en bague d’ouverture sans clics, le Samyang 50mm F1.4 AF II a une ergonomie spécialement bien pensée pour la vidéo, de plus le focus breathing est très faible, ce qui en fait une de meilleures optiques pour la vidéo

Le Sony50mm f1.4 GM est excellent également avec une meilleure ergonomie et qualité d’image mais un focus breathing plus important

Le Sigma 50mm F1.4 DG DN est aussi très bon mais souffre d’un important focus breathing non compensé sur les A7IV

Le Viltrox est le meilleur en terme d’ergonomie et de focus breathing

4.7 Conclusion

The best stay the Sony 50mm F1.4 GM

The Sigma is an interesting offering for up to 42Mpix (only very good sharpness at f1.4 on 61Mpix) well priced if they solve the back focus issue for portraits that I had. It also suffers from quite high chromatic aberrations versus competition

The Samyang 50mm F1.4 II is interesting as the lightest (420g ) and the cheapest (700 euros) with excellent sharpness , bokeh and rendering wide open. It falls short for corners sharpness , build quality and bokeh when used with aperture closed down

The Viltrox is very good and will the best on 33Mpix in term of price quality. Its main issue is the weight

Le meilleur reste le Sony 50mm F1.4 GM

Le sigma est une offre interessante pour le boitiers jusque 42Mpix max (piqué seulement très bon à F1.4 sur 61Mpix), le prix reste raisonnable si les problèmes de backfocus à F1.4 sont corrigés. Il souffre d’aberrations chromatiques plus importantes que la moyenne

Le Samyang 50mm F1.4 II est le plus léger (420g) et le moins cher (700 euros) des F1.4 avec un excellent piqué à pleine ouverture au centre de très beau ronds de bokeh et rendu des couleurs. Là où il est moins bon : piqué dans les coins , rendu du bokeh à partir de F2.8, qualité de construction

Le Viltrox sera le meilleur rapport qualité prix sur 33Mpix sn plus gros point faible étant son poids

6 Conclusion (Français)

Le Viltrox 50mm F1.4 Pro (619 euros) est un très bon 50mm F1.4 à prix très serré: très bon à excellent piqué , très bonne ergonomie, bokeh et douceur du flou d’arrière plan, très bon AF, bonne resistance au flare, très faible AC.

Son point faible principal est le poids qui est un des plus lourd de sa catégorie

Alternatives

  • Sony 50mm F1.4 GM (1700 euros) Un des plus compact et léger de sa catégorie, superbes performances optiques et ergonomie au top
  • Sigma 50mm F1.4 DG DN (969 euros) : assez similaire, excellent jusque 42Mpix,
  • Samyang 50mm F1.4 AF II (700 euros) beaucoup plus léger et piqué meilleur à pleine ouverture, un peu moins bon pour le bokeh et le flou d’arrière plan et pour l’ergonomie

A recommander pour les budgets serrés et pour ceux qui ont un A7IV (33Mpix)
