bright lens, light and well built. The result pictures drawn normal size (10x15) is very good. There is also very correct for visonnage on screen 19 inches and 20x30 prints. The deformations on the edges of images innérentes such focal are still acceptable as long as the frame is carefully or if the wind create special effects prspective. So I do not regret my purchase, especially less than 400 at Amazon!
