XE-1 接 XC 16-50mm 會有桶狀變型？

小弟目前正打算入手 X-E1 並搭配 XC 16-50mm 鏡頭 (為了16mm) + 35mm F1.4 就完整了
但在做功課爬到這篇文章
http://unwire.hk/2013/11/04/fujifilm-xe2/dc/
內文提到:
"不過實際的是此鏡裝上 X-E / X-PRO1 後，廣角端有明顯的桶裝變形，畢鏡這是平價跟機鏡，光學質素當然不能跟 XF鏡媲美"
但畢竟這篇文是在2013年底發表的，離現在也半年了
所以想說 X-E1 或許有出新的韌體來修正 XC 16-50mm的桶狀變型
不尋問手上有這樣組合的大大是否有這樣子的修正呢？
如果沒有…又要陷入尋機之路的迴圈了 ~啊啊啊不要啊~!!
有請大大幫忙解惑~~先謝過了 @___@

ps:剛查了一下官網更新Ver.2.20

內文提到:
2.Function to enable "Command dial" to control aperture setting for XF/XC lens without an aperture ring is added.
This function is for the XF27mmF2.8 and XC16-50mmF3.5-5.6 OIS which don't have an aperture ring. On the Shooting Mode, "APERTURE SETTING" is added and one of "AUTO+MANUAL", "AUTO" and "MANUAL" can be selected.
For detail of how to operate, please refer to the operation manual "Before Using This Product" bundled with above lenses.
<Note>
The "APERTURE SETTING" will be newly appeared, but it is not selectable unless either XF27mmF2.8 or XC16-50mmF3.5-5.6 OIS is attached to a camera.

雖然只是修正光圈環的問題但不知有沒有順便修正桶狀變型…其待ing
