DCL- 4337

Innovative design for digital camera ( DC ) and digital video ( DV ) with 43mm and 37mm threads. It can be use on any telescope with eyepiece size of 1.25".
光學性能優異： 並不是可旋上轉接牙就能接上望遠鏡使用，成像圈問題一直是一般除了NIKON以外消費型數位相機 ( DC ) 及數位攝影機 (DV) 最大的瓶頸，DCL-4337所採用之鏡片經數十種DC及DV測試，絕大部分機種可在光學變焦範圍內完全消除成像圈問題（超大鏡頭機種除外）， DCL- 4337採用高品質兩群四枚非球面鏡片構成，鏡片採全面高級鍍膜處理，有效減低DCL鏡片群所產生的色散及像差問題並提昇透光率，滿足數位攝影玩家的需求。
機械設計穩固：高硬度鋁合金材質，配合特殊螺旋鎖定及微調設計，穩固性及安全性遠高於傳統旋鈕鎖定設計，不但絕無隙動情形產生，更可確保光軸準確性。微調鎖定環具有安全裝置，不會有旋到底脫落的情形發生。外觀採用特殊高質感弧形造型設計，兼具美觀及實用性。
擴充功能強大：DCL- 4337尾端預留了轉接牙，為了減輕折射式系統在高倍率光學變焦所產生的紫光問題，可選購VR紫光濾鏡（Violet Reducer）配合使用，可達最佳效果。另外將DCL- 4337尾端旋下，即可作為近攝鏡使用，光學放大倍率2.2倍，配合DC或DV本身光學變焦，即可作為微距攝影用， 是拍攝昆蟲等微觀世界的最佳利器。

DCL- 4337L

Innovative design for digital camera ( DC ) and digital video ( DV ) with 43mm and 37mm threads. DCL-4337L is mainly designed for LEICA TELEVID 77 spotting scope.
