دوستان کسی تجربه عملی با این لنز روی فول فریم داره ؟
ظاهرا برای فول فریم طراحی شده و دیستروشن قابل قبولی داره... در مورد خطای ca چطوره؟
((بخصوص در مقایسه با 20م.م 2.8))
Designed for use with full frame digital cameras. May also be used with smaller APS-c size sensors with a corresponding effective increase in focal length to about 35mm with most cameras
Two Aspherical glass elements offer correction for distortion
Floating internal focus system enables a minimum shooting distance of 7.1 inches
Dual Focus system allows for easy manual override of the autofocus when difficult subjects are encountered
9 Blade diaphragm provides pleasant out of focus highlights
Extremely compact with a length of 3.36 inches and a weight of a little over one pound
A lens hood, front/rear lens cap and carrying case are included with the lens.
