同時搭配推出的還有一款新款微的"變焦"距鏡
(關於"變焦"微距鏡的部分尚未得到進一步確認)
原文:
A patent for what appears to be a new Canon ring flash has appeared.
We may see a new ring flash with the new macro lens in 2014. We’ve heard about the possibility of a zoom macro lens, but we can’t confirm the information at this time.
◾Patent Publication No. 2014-13350 ◾Publication date 2014.1.23
◾Filing date 2012.7.5
◾Existing ring strobe ◾Xenon tube
◾Process to bend the arc shaped glass tube cylindrical difficult
◾Canon patents ◾There are two areas in light of the strobe
◾Light flux from the first region is subject to direct
◾Toward the object light beam from the second zone enters the prism, and then reflected inside
◾Provided with a step stepped on the reflecting surface, by changing the pitch of the step, it is possible to adjust the distance between the emission point

拿CR的附圖來跟我手上的Canon原廠閃燈比較一下
按原文內的圖樣來看
這款環閃的動力源應該是用600EX等級的燈體
然後把燈頭改成環閃的樣式
如果這環閃最大出力也能到600EX-RT等級的話那就太強大了
(看燈頭的大小出力應該是不至於有那麼猛...不過世事難料咩...)
另外關於微距鏡的部分
如過能做到變焦又能1:1放大
畫質還維持一定程度水準的話
那也挺有賣點的
個人猜測也許是利用把最大光圈做小的方式來達成變焦吧
反正真要拍微距的時候絕大部分都需要縮光圈換景深
相較於能改變焦段讓主題更多元以及架著腳架的時候還能變焦讓構圖更完善的優勢來說
光圈小一點不至於在大部分的微距場合造成太多困擾
