Points forts :

- bonne qualité d'image au centre
- qualité d'image raisonnable sur les bords à la distance focale la plus courte
- faible aberration chromatique latérale
- aberration sphérique convenablement corrigée
- astigmatisme modéré
- faible vignetage sur le APS-C
- autofocus silencieux, efficace et assez précis
- prix compétitif.

Points faibles :

- qualité d'image médiocre sur les bords aux longues focales
- quelques problèmes d'aberration chromatique longitudinale
- distorsion notable avec des éléments de déformation en moustache
- coma trop élevée.

I have to admit the Samyang AF 24–70 mm f/2.8 FE didn't impress me with its performance. During our test we noticed too many slip-ups and medium results for a good contemporary lens with the journalistic 24-70 mm f/2.8 parameters. Mind you, its dimensions and weight are noticeably higher than those of the majority of its rivals.

As a kind of consolation, you get the price – currently the tested Samyang can be bought for about $800, noticeably less than its cheapest rival, the Sigma A 24-70 mm f/2.8 DG DN which is priced as high as over $1100. The prices of brand name lenses of this class start from $1600.

If you look at the Samyang from this perspective, your opinion might become a tad more favourable. In many situations this lens will perform quite efficiently and provide satisfactory photographic results. And you'll pay for it three times less than for many brand name instruments. Still, if you are a photographer who doesn't tolerate compromises you most probably won't be satisfied with it.

Samyang AF 24-70mm f/2.8 FE - Review / Test Report

Commentaire introductif de Klaus sur le forum : "This ain't it" (ça ne le fait pas)

Qualité optique : 2/5
Qualité mécanique : 4/5
Rapport performances / prix : 2/5

The Samyang AF 24-70mm f/2.8 FE has its merits, but its resolution characteristic is, overall, sub-standard. This is especially true at the wide end, where the outer image field is just not sharp enough to compete with the big boys. Sure, it's not terrible when stopping down, but what is the point of buying a f/2.8 lens then? It's actually very good in the middle range, whereas the quality at 70mm is also not that hot again. This may still be OK on 24-megapixel sensors, but beyond that, it's just not good enough. This is a bit unfortunate because the lens handles the secondary aspects rather well. The RAW image distortions are on a sane level, and the RAW vignetting is better than average. The quality of the bokeh is also quite good for a standard zoom lens. Lateral and axial CAs are a bit on the high side, though.

The mechanical quality of the Samyang lens is excellent (other than the poor lens hood) and on par with the Sigma 24-70mm f/2.8 ART, for example. However, it is also way too heavy for what it is. The AF speed is very fast (on modern Sony bodies). The mechanical quality is one thing, but QA is another one. Based on what we've seen in the past, Samyang has often struggled with providing well-centered lenses (centering = optical alignment), and the tested sample was, once again, not ideal in this respect. As long as Samyang doesn't take this more seriously, we have doubts that complex zoom lenses are a good idea for them.

As you may have concluded, we are not overly impressed - overall, the Samyang AF 24-70mm f/2.8 FE is just too heavy and too flawed.
