Sigma EX17-35 /2,8-4,0 DG HSM IF

Zitat: In our opinion, the lens´ forte is its close-up performance, a welcome development in the ultrawide-angle zoom category. If you want dramatic closeups from a wide-angle zoom, and a minimum of linear distortion, you´ll be pleased with this new Sigma.

Zitat: All in all the Sigma 17-35mm delivers a cracking optical performance, and, at less than half the price of a camera maker´s own versions, this is a lens that can´t fail to please.

Zitat: Sigma have taken their upgrade program to digitally enhanced lenses seriously and used the opportunity well. This lens is a shining example in which they have addressed the criticisms of the older model and put them all right without putting the price through the ceiling. With crop factors on digital SLR’s averaging at 1.6x, this lens come out at a 27-56mm equivalent and makes a useful wide to standard walk-around zoom that retains the ability to do some good quality landscape work. In summary the main positive points of the Sigma 17-35mm f/2.8-4 EX DG are: Quick, quiet autofocus. Good build quality Useable filter size Value for money Best at wide end Negative points are: Performance with wide open aperture could be better

Zitat: Zalety: bardzo dobra ostrosc obrazu w centrum pola, bardzo mala dystorsja, niewielka koma, male winietowanie, cichy i szybki autofokus, solidna obudowa, dobre swiatlo, dobry stosunek jakosci do ceny, 3-letnia gwarancja (za doplata mozliwa do przedluzenia o kolejne 2 lata) Wady: wyrazna aberracja chromatyczna na 17 mm, bardzo znaczacy "front-fokus" Ten test podsumuje wyjatkowo krótko. Osobiscie, gdybym mial wybierac pomiedzy testowana Sigma a Canonem 17-40 mm f/4L, wybralbym Sigme. Za wyraznie nizsza kwote oferuje nam ona lepsze swiatlo, lepsza jakosc obrazu, mniejsze winietowanie oraz bardzo mala dystorsje. Canon lepiej koryguje aberracje chromatyczna oraz astygmatyzm i jest troszke lepiej wykonany, lecz zupelnie nie usprawiedliwia to o ponad 1000 zl wyzszej ceny. Trudno tez oczekiwac, ze Sigma po usunieciu w serwisie "front-fokusa", bedzie znacznie gorzej ustawiac ostrosc, tym bardziej, ze L-ka pomimo obecnosci USMa nie pracowala tak celnie jak bysmy tego chcieli.
