D.Abbott tested this Sigma (us$1500) with charts against his own Tamron 35-150 f2-2.8 ($1800-1900) he has been using for a few years. The older Tamron is still superior, but heavy ! Someone deleted the above comment just a few moments ago. Hope it stays. Info: for EACH glass-air interface w/o Matched coating , u Lose 4%.

Z mount 有 red 新鏡都一定快D同無呼吸效應比nikon red用
Leica SL 又有新嘅鏡頭啦

Canon支24-105，內變焦設計拍片都好用
工作人員可接受重量
遲啲可唔可以試下插轉插用喺Z mount嘅表現
心思思緊… 講返本身有Z8, 14-24 F2.8, 70-180 F2.8, 35 F1.8, 50 F1.2, 85 F1.8, 2X, APS-C 有 Zfc, sigma APS-C 16 F1.4, 30 F1.4 (成套APS-C應該會放出去), 一路都冇標準zoom 出左依枝鏡之後覺得依枝好有興趣 28去到105 全程2.8 旅行同影idol舞台表演配合埋70-180 F2.8 同2X都好似夠用 另外諗住雙修埋A7C II 之後睇返騰龍枝28-200 又平又正又輕 旅行嘅話再正啲 但影舞台又好似差少少 覺得點揀好？
依枝好有興趣 我用Z mount 令我好有興趣為左依枝入多部Sony或者L mount
adapter啦，28-105又唔洗機身矯正
@@iamkailong因為本身都有諗住雙修
插落部 A74 度應該係 E mount, 點解係咁同 Canon 比較？難道你哋知道 Canon 即將開放 full frame RF mount 俾 Sigma?
因為simga 仲有l mount 幾個video新老細4k160
28-105 2.8 正wo
我想请教一下 索尼的28-135f4拿来拍照可以的不？ 想出去旅行又拍照又拍视频😂
Video 冇乜得crop 135都好夠用呢，唔去非洲的話
日本製造😍買!!!
Xcd係咪simga
XCD 應該係用日本光學儀器公司
又係無RF mount 吊
唔好吊，等一下或用住sony先，時間唔等人
唔係開放RF mount?
慢慢來,等CANON 比用就得
正野，比Sony 24-105/f4大少少，重少少，貴少少
“少少”=50%🤣
black magic DJI lumix L mount
嘩，香港得你地出片咋喎
盡力為大家講出使用體驗,有問題請提出
Nikon red komodo 8k
個 size 可接受，目視唔覺好大嚿
又係失敗設計-對焦環喺後面
新出先有原廠咁快咋，過一年半載就會負優化。😬😬
真定假啊？咁衰？期待Z口版。
@@tailand2005 又咁講，更新完只係慢過原廠鏡，但依然快過其他品牌。😂
Sony會update 個firmware去優化’對焦太快‘呢個問題。
@@icecool518 sony咁搞法真喺好抵死
某國測試做假比其他國家出名，不過出咗名無人在意，因為某國在唔少香港人放篤屁味道比其他香。咩in其實都係表面嘢
DJI都係用家!
