1.DC片幅增大因鏡頭不可交換的關西在微距拍攝時，對焦距離勢必增加，這點在DC相機很多都已做到1公分對焦G12也是。
2.片幅增大，但鏡頭不可交換，以一般觀念來說變焦鏡頭都不銳利，用這麼大的片幅卻只能有一顆固定鏡頭來拍攝，只能說我有一個性能很好的武器但只有一個阿兵哥可以操作，不過片幅增大想必高ISO時畫質可以預見比較好。
3.G1X是否可以PK EVIL大概是個未知數，要等上市半年或一年後才可看得出來，但以我在DC M4/3 DSLR用過這幾年來看(純個人觀念)我並不認為G1X可以攻占EVIL市場，原因大概在:近拍無法跟DC一樣做到微距拍攝，散景方面片幅增大卻只能用一顆固定變焦鏡頭來拍攝，光圈方面是必無法做到大光圈散景，G1X的最大光圈F2.8看起來不錯，但還是沒EVIL或DSLR鏡頭可以換成大光圈鏡頭吸引人，那種F1.8 F1.4 F1.2 大光圈拍出來的定焦鏡魅力，只有拍過的人才知道甚麼叫一拍就被強烈吸引住的畫面。
G1X不可否認在片幅增大之下確實很吸引人，對使用DC很多年的人來說一鏡到底確實也方便，但對升級到EVIL和DSLR多年用戶者卻沒那麼吸引人了。

MZD1250的放大倍率已經達到等效1:1.4...這樣的放大倍率已經只剩下正統微距鏡可以勝過它
G1X在最廣角端的最近對焦距離是20CM，望遠端是85CM，我猜是完全不能跟MZD1250比的
官方沒寫出G1X的實際或等效放大倍率，但我想是要是有1:5就要偷笑啦

It is not my article. It is the paragraph from the professional reviewer at Dpreview. I post it here at #35 floor. You can check the preview of D1X at Dpreview. Again:
"Sensor size and aperture: relationship to low light image quality and background blur
The G1 X has a much larger sensor than other fixed-lens compacts, which implies it should offer much better high ISO image quality. But for fixed-lens cameras, that's only half of the story, and lens speed plays a crucial role when considering low light performance. Smaller-sensor cameras such as the Olympus XZ-1 and Fujifilm X10 sport lenses which are rather faster than the G1 X's, by a stop or more at wideangle and two stops at telephoto. This means that, under any given lighting, you can always use lower ISOs with these cameras. This will go some way to offsetting the G1 X's larger-sensor advantage - especially at telephoto.
Much the same reasoning applies when considering how well each camera will be available to deliver blurred backgrounds when shooting portraits. Here the optical calculations deliver an answer that some may find surprising: when shooting portraits at the long end of the zoom with the lens wide open, the G1 X will offer little advantage over either the X10 or XZ-1 in terms of subject isolation and background blur. Of course this isn't anywhere near the whole story with regard to overall image quality, but it's worth knowing."
G1X is not better than XZ1 or X10 in low light and background blur but double of their price!

Please becareful the words you used - 打趴, 完敗!
Olympus users are polite and don't care much about it.
You better not use these words to Nikon or Sony users!
Beside 廣角28對比24敗,
lens 3 proofs 敗.
lens sharpness and quality 敗 (90% correct)
lens macro function 敗
touch screen 敗
art filters especially the evil filter 敗
screen AF 敗
1:2.7 high quality jpeg 敗
super fast AF 敗
more accessaries 敗
different body color option 敗
changable holder 敗
I use only EPL1 not EP3. EP3 users may give you another 10 reasons 敗 敗 敗!
We just want to discuss the facts politely and respectly. :-)

"如果一台DC要塞進略大於M4/3片幅,
同時又要擁有約等效28-100以上的焦段,
如果廣角端的光圈要做到F2.0的話,
是否在鏡頭設計上更困難,也更大了?"
I am not in the optical field thus cannot give you any suggestion.
From technical point there is no problem to make this kind of lens.
Pana is making the f2.8 zoom and still looks pretty small.
With Pana's X technology a small f2.0 zoom is possible.
However the price may out of our imagination.
I would say NT $60,000 is a must.
Do you know people now are asking for XZ2 with the similar design?
4/3 sensor with large lens!
Olympus are listening...
