When the sky seems like it simply goes on forever, you can make the most of the moment with the Distagon T* 2, 8/21. An expert at capturing spectacular landscapes & incredible scenes, it will make your compositions infinitely more dramatic. The Distagon T* 2, 8/21 is a super wide-angle lens & is the leader in its range. Thanks to its aperture of 2.8 & its non-reflecting & virtually distortion-free characteristics, it will help you create spectacular compositions full of variety, dramatic contrast & deep, vivid colors. When wide angle views go to extremes & beg the control via an SLR viewfinder, which means that the back focal distance has to be much larger than the focal length, a retrofous design called Distagon is the right choice. Dramatic perspectives & a view from extraordinary image angles – ZEISS lenses open up new composition possibilities. Distortion would disrupt the composition because straight lines, whose image does not go through the image center, would be reproduced with a curved shape. This annoying effect is accordingly & largely compensated through elaborate optical designs at all focal lengths.
