佳能宣布在香港推出新一代EF 24-70mm f/2.8L II USM標準變焦鏡頭。香港售價為 $18,800,並於 9 月 7 日起開始發售。以下是詳細資料:-
更高層次的影像質素
隨著數碼影像技術的急劇發展,攝影師對鏡頭質素要求更高,因此佳能為新一代鏡頭配備更優越的光學設計,實現更高質素的完美影像。EF 24-70mm f/2.8L II USM標準變焦鏡頭採用全新研發13組18片鏡片光學設計,其中1片超高精確度研磨(Ground)及2片高精確度玻璃鑄模(GMo)非球面鏡片,能大大修正變形、視場彎曲等各種鏡頭像差,為整個畫面帶來更高質素影像;而1片Super UD超級超低色散鏡片及2片UD超低色散鏡片,則能有效消除廣角焦段的橫向色差及色彩模糊現象,更改善了遠攝端的軸向色差,達致更高解像度及高反差影像。鏡頭更採用9片圓型光圈葉營造優雅散景,加上專為數碼攝影優化的鏡片塗膜,確保優越的色彩平衡及有效減低鬼影和眩光。
更佳操控性 極速捕捉每個精彩畫面
EF 24-70mm f/2.8L II USM整個焦段的最近對焦距離均為0.38米,讓攝影師以更近距離拍攝微細主體,呈現更多影像細節。鏡頭的環型超聲波馬達(USM)配合內對焦設計及優化的自動對焦演算法,能保證高速、寧靜及精確的自動對焦表現,讓攝影師快速掌握每個拍攝良機。鏡頭更提供全時手動對焦功能,使用自動對焦模式拍攝時,仍能隨時以手動對焦作精確調校,帶來更具掌握的靈活對焦操控。此外,憑著f/2.8大光圈的優勢,即使於昏暗環境下拍攝仍能保持快速對焦,令拍攝更具彈性,不論紀實或風景攝影同樣應付自如。
堅固耐用 輕鬆應付嚴峻戶外拍攝環境
全新鏡頭結集多項針對用家需要的設計改良,透過經優化的變焦結構,令鏡身更輕巧並提升其堅固耐用性,滿足專業攝影師的需求,以應付嚴峻的戶外拍攝環境。全新改良的鏡頭結構經過反覆電腦模擬驗証,大大加強變焦部分的耐用性,並能加強鏡身的抗震及抗衝擊能力。鏡頭僅重約805克,較上一代減輕達15%,鏡身長度進一步縮短,大大加強機動性,方便攜帶外出使用,隨時拍攝。此外,鏡頭最前端及最後端鏡面均加入氟塗膜(Fluorine Coating),減少塵埃、污垢及指紋依附,讓鏡片更易於清潔,以確保影像質素。鏡頭更採用防塵防水滴設計1,以應付不同天氣狀況。使用新增的「變焦鎖」,能方便攝影師於攜行時將鏡頭鎖定於24mm端,避免鏡頭伸長造成損壞。

Hello Web Admin, I noticed that your On-Page SEO is is missing a few factors, for one you do not use all three H tags in your post, also I notice that you are not using bold or italics properly in your SEO optimization. On-Page SEO means more now than ever since the new Google update: Panda. No longer are backlinks and simply pinging or sending out a RSS feed the key to getting Google PageRank or Alexa Rankings, You now NEED On-Page SEO. So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword….wait there’s even more Now what if i told you there was a simple WordPress plugin that does all the On-Page SEO, and automatically for you? That’s right AUTOMATICALLY, just watch this 4minute video for more information at. Seo Plugin
