Just can't stay away 註冊日: 2006-02-26 來自: Taiwan 發表數: 167	[34554] Re: SIGMA APO APO 50-500mm F4-6.3 EX DG HSM for 4/3 引文: collective 寫道: 原物料都在漲價,為什麼產品不能漲價反應成本,感覺很怪有機身防手振的機身都比沒有的貴嗎?好像也不盡然.... 有VR多了電子零件就可以貴,那若是在別的地方多用點好料不知道要賣貴一些可不可以? 這也是為什麼敝人一直喜歡玩一些老鏡的原因, 尤其是俄國的老鏡, 這些老鏡沒有af, 沒有vr, 什麼都沒有, 有的只是沉重的鏡片組, (我有一顆300/3.5 光是鏡組的重量就有2kg了, 可是加上鏡身也沒多幾百克), 很像ak-47的感覺, 因為沒有太多的特異功能, 更重視原本的表現我一直很好奇, 這些大口徑的鏡頭(300/2.8, 400/4, 800/5.6...)的af倒底是怎麼驅動的, 尤其又要做到快而無聲, 以我的300/3.5及200/2.8這兩顆電影鏡而言, 光鏡片就快2kg了, 光是要帶動鏡頭所需的力量就不小了, 這些大口徑的鏡頭的af, 倒底是怎麼驅動的
