Пользуюсь сигмой Sigma AF 24-70mm F2.8 IF EX DG ASPHERICAL HSM . Уже полтора года. Имею сказать следующее:
Основные особенности:
— бритвенная резкость на 8-11;
— очень быстрая фокусировка (HSM-мотор сигмы);
— легкий софт на 2.8 на некоторых фокусных и/или в некоторых условиях освещения;
— дорогущие фильтры под 82 мм.
Отсебятина
Оптика, которая оправдывает свою стоимость в 30 т.р. полностью. Использовалась мной не раз как для репортажных, так и для художественных съёмок. Прекрасно фокусируется в любых условиях кроме контрового света (как и вся остальная виденная мной оптика), хорошо держит этот самый контровый свет. Красивого зайца поймать, к сожалению, невозможно.
Что касается веса, на который часто жалуются: я не видел ни одного светосильного зума, который бы весил немного. В данном случае пара Nikon D700 + Sigma получается отлично уравновешенной.
Что касается влагозащиты: официально она производителем не заявлена. Лично попадал с ней под дождь два раза. Пока все ничего.
Что касается геометрических искажений: присутствуют на широком угле, однако, третий Lightroom умеет править их автоматически (имеет профиль для данной оптики).
