Mounted between the camera and lens, it doubles the focal length of the attached lens, turning a 100mm into a 200mm or a 135mm into a 270mm. It is a compact and efficient way to extend the reach of your Zeiss lenses.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eAs a Carl Zeiss optical design with T* multi-coating, the Mutar I is built to maintain contrast and color fidelity, preserving much of the character that makes Zeiss lenses so admired. It performs best with high-quality prime lenses and when stopped down slightly. The result is a practical increase in focal length while retaining an attractive Zeiss rendering.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eThe Mutar I maintains automatic diaphragm coupling, so you can compose and focus at full aperture while the lens stops down during exposure. Because it doubles the focal length, it reduces the effective aperture by two stops; for example, an f\/2.8 lens becomes f\/5.6. TTL metering on Contax bodies automatically accounts for this change.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eThe converter is compact and light, taking up very little space in a camera bag compared with an additional long telephoto lens. Its solid build matches the quality of Contax lenses and bodies. It allows you to carry a smaller kit while still having long focal lengths available when needed.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eThe Mutar I is especially useful with short and medium telephoto lenses, creating longer focal lengths suitable for portraits, wildlife, nature and sports. It can also increase close-up magnification, since the minimum focusing distance of the attached lens stays the same. This adds versatility for flowers, insects and detail shots.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eThe teleconverter is designed for Contax\/Yashica C\/Y-mount cameras such as the Contax RTS series, 139 Quartz, 167MT, Aria and S2, and works with Carl Zeiss C\/Y lenses. With a C\/Y adapter, the combination of Mutar and lens can also be used on Sony E, Fujifilm X, Canon RF, Nikon Z, Micro Four Thirds and L-mount mirrorless cameras. This gives Zeiss lens owners a simple way to extend their reach on modern bodies.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eTeleconverters from the Contax system remain valued because they allow photographers to multiply the usefulness of their existing Zeiss lenses at a fraction of the size and cost of additional telephotos. The Mutar I's Zeiss design and coatings make it a natural fit for a high-quality Contax kit. It is a thoughtful accessory for both film and adapted digital use.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 12px 0;\"\u003eIf you own Carl Zeiss C\/Y lenses and want to extend their reach without carrying additional heavy lenses, the Carl Zeiss Mutar I 2× teleconverter is an excellent choice. It offers Zeiss optics, automatic coupling and compact convenience. It is a practical way to expand the creative possibilities of your Contax system.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n \u003cdiv style=\"color: rgb(44, 62, 80); font-family: Arial, Helvetica, sans-serif; margin-bottom: 24px; background: linear-gradient(135deg, rgb(244, 249, 255) 0%, rgb(232, 242, 252) 100%); border: 1px solid rgb(207, 224, 241); border-radius: 10px; padding: 18px 20px;\"\u003e\n \u003cdiv style=\"font-size:20px;font-weight:bold;color:#173b63;margin-bottom:8px;\"\u003e\n Specialty Store for Used Cameras \u0026amp; Lenses\n \u003c\/div\u003e\n \u003cdiv style=\"font-size:15px;line-height:1.9;color:#42586e;\"\u003e\n We are a Japan-based specialty store focusing on used cameras and lenses.\u003cbr\u003e\n Our items are carefully inspected and described as accurately as possible for international buyers.\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003cdiv style=\"color: rgb(44, 62, 80); font-family: Arial, Helvetica, sans-serif; margin-top: 30px; text-align: center; padding: 20px 10px 4px; border-top: 1px solid rgb(214, 228, 240);\"\u003e\n \u003cdiv style=\"font-size:18px;color:#173b63;font-weight:bold;\"\u003e\n Thank you very much for your understanding.\n \u003c\/div\u003e\n \u003cdiv style=\"margin-top:8px;font-size:13px;color:#6f8dad;letter-spacing:1px;\"\u003e\n Peekaboo Japan       \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e","brand":"Carl Zeiss","offers":[{"title":"Default Title","offer_id":50521551208586,"sku":"20261011JPY","price":64.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/2977\/4474\/files\/s-l1600_31271b0b-df48-420b-9771-6f0f66a2870f.jpg?v=1792511242","url":"https:\/\/peek-a-boo-camera-japan.myshopify.com\/ja\/products\/w-capscontax-carl-zeiss-mutar-i-2x-teleconverter-for-c-y-japan-e0646","provider":"PEEK A BOO CAMERA JAPAN","version":"1.0","type":"link"}
