剛在kakaku.com得知此超廣角將於4月29日發售, 期待各大大的神速開箱文, 對於此罕有超廣角及其FLD鏡片與螢石質素的比較有點期待!! 不過暫時是canon mount先發售, 其餘mount發售日期未定。售價要近95,00日元也不便宜呢! 附上原文連結供各大大參考。

17-50跟這個都很讓人期待...
希望17-50一來可以把B005的價錢打下去`

FLD glass has been incorporated into some of our recently announced lenses; 4 elements have been included in the Sigma 8-16mm F4.5-5.6 DC HSM as well as 2 elements in both the Sigma APO 70-200mm F2.8 EX DG OS HSM and the Sigma 17-50mm F2.8 EX DC OS HSM.
Sigma 8-16mm F4.5-5.6 DC HSM =>APS-C專用,有四片FLD(不惜重本).
光圈稍大.不過超廣角也不需要大光圈吧?反而是色散控制比較重要,所以用了四片人工螢石可以理解
Sigma 17-50mm F2.8 EX DC OS HSM=>APS-C專用,F2.8恆定光圈,二片FLD,力戰N/C二家APS-C鏡皇
Sigma APO 70-200mm F2.8 EX DG OS HSM=>全幅可用,3片SLD及2片FLD,力戰C家小白兔及N家小黑六.
怎麼不再出一支配有FLD的50-250mm望遠鏡頭,APS-C專用,恆定F4即可?如果恆定F2.8更讚!
這樣剛好湊成APS-C大三元,焦段8-250mm?
