Portraits

  • Portraits rendering are very good to excellent on all the selected lenses , but the 45mm F1.8 lens offers superior performances thanks to their better separation with the background. The TTArtisan and 7 Artisans are the least good ones due to the lack of softness of the background blur

Autofocus

AF of the Sony is better than on the Samyang . In third position the Viltrox. , then the 7 Artisans.The TTArtisan is the least good one

L’AF du Sony est meilleur que celui du Samyang , le Viltroxest 3eme, le 7 Artisans 4eme. Le TTArtisan est le moins bon

Video :

Ergonomics for video are best on the Sony 40/50mm F2.5 G, and on the 7 Artisans but the other lenses opening at F1.2/F1.8/F2 provide more creative possibilities thanks to their better aperture

L’ergonomie en vidéo est meilleure sur les Sony 40/50mm F2.5 G , et le 7 Artisans mais les autres optiques ouvrant à F1.2/F1.8 /F2 offrent plus de possibilité créatives

Conclusion

Overall the Sony is the best lens in term of Size, sharpness, resistance to flare, ergonomics, build quality , the only area were other score better is for portraits with better bokeh balls/background blur when they offer a F1.2/F1.8 aperture and/or a longer focal length

The Viltrox is offering 80% of Sony performances for 25% of the price of The Sony

The 7 Artisans and TTArtisan are at same price of the Viltrox and same form factor but is significantly less good

Globalement le Sony est le meilleur en terme de taille, piqué, resistance au flare, ergonomie, qualité de construction. Le seuls point où les autres sont meilleurs est en portrait avec une meilleure forme des ronds de Bokeh, plus de flou d’arrière plan

Le Viltrox lui offre 80% des performances du Sony pour 25% de son prix !

Le TTArtisan et le 7 Artisans sont très similaire en prix et taille que le Viltrox mais nettement moins bon
