The super wide-angle lenses is ideal for photographing vast, far-stretching landscapes and breathtaking scenery.\u003c\/p\u003e\n\u003cp\u003eThe ZEISS Milvus 2.8\/21 super wide-angle lens of the type ZEISS Distagon is the best in its class. Thanks to its maximum aperture of f\/2.8, the reflection-free and practically distortion-free super wide-angle lens is perfect for spectacular image compositions of great diversity, dramatic contrast and vivid colors. The further optimization of the lens coating reduces ghosting and flare effects in critical light situations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExcellent imagery, even in difficult light conditions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOutstanding stray light reduction is achieved by combining a number of optimally matched measures. In addition to the ZEISS T* coating, all lens edges are provided with a special pitch-black lacquer in a complex manual process. Light traps in mechanical components and specially designed surfaces are integrated to prevent the occurrence of reflections.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFuture-proof solution for high-resolution camera systems\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe excellent image performance of the ZEISS Milvus Lenses is sharply focused on the requirements of current and future high-performance digital cameras. Thanks to the low level of stray light allowed by the lens design, high-contrast images are also possible with increasing high dynamic ranges of the sensors (HDR). The optics are designed to ensure full utilization of the performance provided by high-resolution camera systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCreative still and video photography through precise, manual focusing\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eManually focusing a lens means controlling and therefore actively composing an image gently and precisely from your fingertips. Here, a good ergonomic design makes all the difference. ZEISS Milvus Lenses feature a large rotation angle which enables pinpoint focusing. The silent, continuous aperture setting (de-click function with ZF.2 mount) and the long focusing range lay also optimal conditions for video photography.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLong-lasting product with protection against environmental influences\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eZEISS Milvus Lenses will impress you not only due to their visual and haptic excellence, but also thanks to their inner qualities. Special seals for protection against dust and splashes expand the photographer's creative potential by guaranteeing the system's functional reliability even in environmentally difficult situations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStable image performance over the entire focusing range\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Floating Elements Design permits constantly high image performance in the focal plane – from the minimum object distance to infinity. This is accomplished by changing the axial distance between individual lens elements or element groups. The mechanical design of the ZEISS Milvus Lenses is highly complex and the workmanship must be extremely exact – both specialties of ZEISS.\u003c\/p\u003e\n\u003ch5\u003eWhat our Experts
