評價:
i paid a lots of money to buy it
for it's super tele , and f4 aperture
it's worth if you prepare to use it for a very long time , for example more than 10 years
you will not disappointed on it
although i have some regret on it - why not buy a cheaper , lighter , smaller lens 500mm
since this lens is too heavy for almost all peoples .
i keep gyming atleast twice a week . but still agree that the lens is too heavy ..
maybe i need more time to custom it.
however , the lens have good outlook , good quality
after you took some amazing pictures , you will forget how heavy is it . haha
if you have enough money , go for IS2 VER. since it is 1.7kg lighter than IS1 but trust me , IS you seldom use it . no need to consider about it .
if not but you want a super lens like this .
just consider 500mm or this lens (second hand ) if you don;t want sigma ..haha

缺點:
貴(SIGMA 856 只係6成價錢)
沒有獨立的鏡頭蓋 ,得個皮套.
個膠箱唔加個輪比它可以拖住走...搞到有等於無
超級重
其他配件(腳架,雲台) 又一筆錢

評價:
缺點 真的係貴同埋重 ,連小白都有好多人轟這2個缺點
何況是這支比小白重4倍,比小白2貴5倍的物體...
每次拎它出去都辛苦得要命
坦白說
這鏡的成像真的無可挑剔 如果要比,我覺得它全開光圈解像力似小白收光圈到F4.5 左右
平時都加個1,4X 上去用 在FF 機上都可以發現暗角非常小
對焦都好快 (因為鏡片算大...此鏡對焦算快
這鏡放在家中供奉
看著白白的鏡身 粗粗的變焦環 看著也養眼 心中舒服
這鏡放著看的功用比較大 (一個月拎不到一次出街)
光學質素.......沒有如MTF圖中那麼頂點 ...至少唔算非常利 放大至80%左右,清楚看見其解像力下降,有少少紫邊問題出現, 色水也偏淡
而全開光圈的畫質與最佳光圈f8相差無幾 f13以後因鏡內衍射做成解像力下降則相當明顯
做功.....全金屬 全天候防塵防水滴 , 令人安心信賴
對焦...用LIMIT 時好快..1秒左右 FULL 就2秒多點..由最近到無限遠 而且由於光圈F4 ,對焦比856 快得多
重量.....有5.7kg 手持是不可能的 , 想也別去想
它本身有記憶對焦.....一按可以還原原本焦點 (幾好用)
另外就係副廠大炮的長鏡實在外觀好普通
CANON 的白炮相對耐看好多
現在一代停產...2代雖然輕不少...但幾近十萬先買到.....而光學質素差不多..
2手市場少人賣,更顯此鏡地位....相當保值
但584或更舊的,500 4.5 輕和細得多 684 太重以致使用率低
有心考慮的朋友慎重比較兩支分別,這在showroom 感覺不到, 但長期使用必成負擔
