Samyang AF 85 mm f/1,4 EF

Autrement, j'attends de voir ce qui va se passer au niveau ML ces prochains temps, mais une version similaire en tirage court, je vais acheter illico..

Si ty regardes le 14mm AF en versions EF et FE, ca donne une idee de la taille de la version ML.

J'espère que non !!! que l'avenir c'est pas ça (j'intègre un adaptateur EF) !, parce que avec 3 optiques ML de ce type dans la besace, il n'y a plus aucun intérêt à avoir un ML avec son capteur à nu quand on change d'optique et les boutons rikiki incompatibles avec mes doigts... j'espère bien une monture à l'image de la version EF-M adaptée en largeur aux optiques FF+AF... c'est au moins radicalement plus compact et beaucoup léger que les versions EF-S

Samyang AF 85mm f/1.4 EF - Review / Test Report

Commentaire introductif de Klaus sur le forum : "Close but no cigar ..."

Qualité optique : 1,5/5 à 2/5 sur capteur 50 Mpixels, 2,5/5 sur capteur 21 Mpixels
Qualité mécanique : 4/5
Rapport performances / prix : 3/5

Size matters ... as we all know ... but it shouldn't be everything really and the Samyang AF 85mm f/1.4 EF sacrifices an even quality distribution across its focus range for compactness. That doesn't mean that it is a bad lens in real life. Even at shorter focus distances, the center quality is usually good enough if you stay at least a bit away from its minimum focus distance and the mediocre borders don't really matter all that much here anyway. Near infinity focus, the sharpness is actually very high across the field (stopped down). Lateral CAs aren't overly impressive with higher than desirable aberrations from f/2.8 onward. Image distortions are usually not noticeable. There's some heavy light falloff at f/1.4 but that's nothing unusual for an ultra-large aperture lens. The bokeh is not without issues. While the sheer capability of producing a shallow depth-of-field is impressive, there is a bit too much smearing in the focus transition zone. Out-of-focus highlights are nicely rendered though.

Samyang did a good job with respect to the construction quality of the lens. They used decent quality materials albeit they stay a tad below the level provided by the more established players. The weather sealing is certainly commendable albeit it is unclear whether it's more than just about the mount gasket. The AF speed is high. The focus calibration was way off in our sample though. As mentioned, the primary value proposition is the compact size and low weight of the lens - nothing in this lens class close really.

The Samyang AF 85mm f/1.4 EF is certainly an interesting lens also regarding its comparatively low pricing but in terms of image quality, it is inferior compared to its competitors. Maybe the next incarnation of this lens will feature a floating system for close focus correction which could overcome the mentioned weak spots. After all, the world is full of high-performance lenses in "brick" format but there are just a few manufacturers focusing on more compact alternatives.
