Pros: Sharpness, size and weight quite contained despite the focal range, really good materials
Cons: Lack of tripod ring to buy separately, sigma quality control that leaves me slightly perplexed, not tropicalized
Opinion: After almost a year of use I got a concrete idea about this lens that was literally a relationship of love and hate. Let's start from what has negatively marked my experience with this perspective; The first specimen I bought (fortunately through amazon) arrived with the electronics totally non-functioning, it did not communicate electronically with the camera body, fortunately I could make the immediate return. The second model, purchased on a well-known Italian shop, left me very perplexed right away for about a month of use. I noticed a fairly marked tendency to knead and total loss of microcontrast and fine detail. Initially I blamed myself because I had never used optics of this type, and maybe I still had to become familiar, especially in the management of air density, choosing ideal days, but despite doing tests even at home the results were still very bad, moreover, comparing myself with various photographers and even here on the forum my experience of use was totally different from what were the feedback released about this lens. So after several attempts I discovered that I had the rear lens "fogged up", I could not even define what it was, it was a very light patina above the rear lens, moist, almost muddy, visible only through the flash of the phone, which covered the rear lens, fortunately externally. It was not easy to see this problem or clean the lens totally, as the rear lens resolved very inside the back of the lens, but with a little patience and with the help of the classic pallets for cleaning the sensor I finally managed to do justice to this lens that is really very surprising in terms of performance. As for this strange fact, I do not know if it is due to sigma or to the shop that sold it to me, the fact is that anyway the lens arrived to me perfectly packed and with all the seals closed, so I strongly doubt that it is due to those who sold me the lens. Another negative point is the lack of the tripod ring that must be purchased individually and costs about € 150 that owner sigma and € 60 that of third parties but that still offer a very good quality, honestly I do not understand this commercial choice, I consider the tripod ring indispensable on a lens of this type. The lack of tropicalization is clearly the compromise that requires this lens, but still has an excellent build quality, the attack is however tropicalized, but the body of the lens is not tropicalized, but I still used it in situations of very high humidity at dawn and did not give me any kind of problem. Its points in favor are definitely the size and sharpness. At the center is really a blade at practically all focal lengths, loses something from 300 to 400mm but it is really about looking for the hair in the egg, and solves with eyes closed the 43mpx of the a7rIII and almost certainly has no problems even on the older sisters from 61mpx. I find it very sharp at all openings (clearly at TA loses a little bit) but the best of itself seems to give it to f11, returns literally sharp files. |
