Conclusion

The Sigma 12mm F1.4 provides the best results globally in term of sharpness consistency + smoothness of background blur and best bokeh balls, followed by the Sony 11mm F1.8 If you don’t need the F1.8 aperture the Sigma 10-18mm F2.8 DC DN is excellent and very versatile

The Yongnuo has the best price performance ratio and is excellent in term of centre sharpness and ergonomics. Its only weaknesses are the corners that need an aperture of F5.6 to reach good level. The Samyang is less good than the Yongnuo and more expensive

Le Sigma 12mm f1.4 fournit les meilleurs résultats globalement en terme de consistance sur tout le champ + douceur du flou d’arrière plan, suivi par le Sony 11mm F1.8 . Si on a pas besoin d’une ouverture F1.8 , Le Sigma 10-18mm F2.8 DC DN est excellent et très polyvalent.

Le Yongnuo a le meilleur rapport prix performances et est excellent en terme de piqué au centre et en terme d’ergonomie. Sa seule faiblesse est le piqué dans les coins qui ne devient bon qu’à F5.6. Le Samyang est moins bon et plus cher
