The following opinions have been automatically translated with Microsoft Translator. | Samyang AF 85mm f/1.4 EF Pros: material quality, very light, good sharpness from f2 onwards, good containment of reflections Cons: fire point difficulty in MF, chromatic aberrations in the out-of-focus, not finely calibrated for AF (at least my model had a constabable FF), vignetting (structural with this type of lens). Opinion: light (aluminum) but solid, compact, beautiful to see and good finishes. Autofocus fast enough, critical to use in mf for the very low depth of field note. As soon as I took I encountered a serious front focus problem that I partially corrected in the car. I say partially because a "pelino" could still be corrected but the calibration scale had reached its maximum. Since many report ff and bf problems for this manufacturer I would not like that, in addition to the wide tolerances of Asian production, there was not a kind of "desired defect" in order to be able to sell dock stations as well. Focus ring maybe too smooth. I'd like to be more clutched. in backlight I do not notice annoying reflections despite having a very generous frontal lens. However, leave the lampshed mounted to defend the lens. The defects are typical of an unbleached light optics: the well-known vignetting at full opening, at least for me, is quite annoying but countervailable of clean room. The sharpness at f 1.4 is not much but at f 1.8 it already improves. From f 2 onwards nothing to say. A sore point are the chromatic aberrations, also these partially correctible: at f 1.4, radially and in the backlight parts, they are quite evident. They decrease proportionally to the closing of the diaphragm. Good lampshed, discreet packaging. A good purchase if bought not at full price. Excellent QP ratio when taken used. Update: Compared for a full day to the glorious old focal pari SIGMA, both freehand and stand trials. basically they have the same resolving power at the center. same incisiveness at all openings, both in the center and you have edges. the sigma has less, but of very little, vignetting and in any case still manageable in post production. the sigma, to the touch, is more solid, heavier and longer. the maf ring is direct grip while in the samyang it is electro-assassist (I do not like it but they are tastes). The samy beats the sigma in fire speed. the latter struggles to focus in low light conditions. chapter apart from chromatic aberrations: I had never used lenses so large. ac are proportionate to the size of the lenses. this defect is identical, in quantity, in both optics. I repeat that for SLRs, in absences of fire assistance aids, the point of fire remains really difficult to find. sent on January 20, 2021 |
