为何有呢个问题/结论?

bigger sensor , better photo quaility ? sensor 是越大越正?
if not, no point for DSLR full frame

DC: Canon 1.5 inch Vs Sony 1 inch
in theory , 50% sensor bigger, it means Canon sure wins.
but reports say Sony wins, why?
I doubt those reports, or the theory is wrong? any comment?

啲评测报告唔系只睇画质,仲有好多方面综合咁睇,好似操控性,便携性,使用方便性等等.

可能因为canon 缩水
话就话1.5寸sensor, 实际成像系裁左四个角
得返1.9x crop（接近m43）

Ps g1x 系用足成块sensor 成像的

同意你的意见, GX1 画质一定好过 RX, 其他表现就见仁见智

that's why I ask!
e.g.

http://www.dpreview.com/reviews/canon-powershot-g1-x-mark-ii/7
「These examples (and our test scene on the coming pages) suggest that the RX100 II's sensor is so much better than the G1 X II's that it cancels-out much of the dynamic range and high ISO noise advantages that the G1 X II's larger sensor should bring.」

93 Vs 83

because the Canon uses a sensor that appears to have a lot in common with the 18MP APS-C chip it first introduced in 2009, while the Sony uses the latest BSI CMOS technology, the difference isn't as large as you might expect

因为Canon用旧野

另外好多sensor都系Sony造。手机系，Nikon 800E个FF sensor又系Sony，Nikon 1果Ｄ一吋sensor又系Sony。Panasonic都有用Sony sensor

but reports say Sony wins, why?
----------------------

咁讲, 使乜有report. 只睇1.5" vs 1" 就知边个win啦, 系人都识.

实际成像系裁左四个角? 系同135片幅(36x24mm)比较吗?
有关crop factor, 可参考以下:

Nikon DSLR crop factor 1.53x
Canon DSLP crop factor 1.62X
G1X mark II crop factor 1.92x
M4/3 crop factor 2x
RX100 crop factor 2.72x

The Canon G1 X is the biggest compact digital camera ever from Canon. It's bigger because it uses the largest sensor ever crammed into a compact digital camera by Canon, a healthy 14 x 18.7mm (1.85x crop factor) CMOS chip.
