Pros: First of all the combination: "extreme sharpness at full aperture-wonderful bokeh": its absolute dowry more worthy of note! Then the construction very "pro".... Optics that in his hand feels so robust, "true"!
Cons: The AF not always very precise... Often a little uncertain in the "stop" the focus, definitely not very reactive in the micro changes of focus.... However, let's face it, at F 1.4, opening with which I use the optics in 80 percent of cases, I really would be in trouble to say when is the optical AF to err and when, conversely, I am not "center" correctly... At these openings we really talk about a few inches of depth of field...
Opinion: Excellent value for money I possess (still currently) the Samyang 85 1.4, beautiful, and I had, before this Sigma, the Nikkor 85 1.8 G (aesthetically, by the way, much more plasticoso): the latter, for goodness sake, excellent lens, sharp already at full aperture, beautiful colors, but..... It wasn't and it's not a f 1.4, let's face it too! The bokeh was very very pleasant, but without being able to have that effect (wonderful!!!) fairytale and dreamy that gives me this Sigma (and that, of course, give the homologues Nikkor)! Moreover, my personal opinion, the 85 1.8 g always gave me the impression of being too "saturated" in the surrender, almost "contrived" in some situations of light.... The Sigma I find it a more neutral and pleasant rendition... At 1.4, I repeat, it's a real blade, crisp... That is: I, practically, use it almost only at full aperture and I never found myself having "regretted" not having closed a bit ' the diaphragm to have more detail. The only real flaw and Achilles heel of the lens, is the autofocus. Not so much for the slowness, or for the lack of precision (I have not noticed phenomena of back or front focus in any of the 4 reflex with which I used it)... As for a certain physiological "indecision" in taking the focus point. Same behavior that also have the Sigma 50 1.4 old and the Sigma 30 1.4 old (pure from me used). Nothing particularly serious, however, I recognize, the phenomenon can become particularly annoying species if you want to "run after" to moving subjects (like: My baby!). In this sense the Nikkor 85 1.8 G was indisputably better. The price in the used is very palatable. |
