Canon PowerShot G系列整理

Canon PowerShot G是佳能旗下PowerShot數位相機的一個系列。
G系列作为CANON消費級數位相機的旗艦商品，最大特點就是成像品質的專業化——不輸單眼相機（連拍除外）。
G系列提供熱靴接口可以外接佳能EX系列閃燈，配備鋰電池，可旋轉LCD螢幕（從G7開始取消旋轉，在G11上又跑出來），支援RAW格式輸出（在G7上一度取消，在G9上又恢復支援），支持大光圈的鏡頭，高速的反應時間。
G系列一共有10个型号，最新款是2010年的G12。

其中Canon也避開了中國人避諱的G4，以及G8這兩個型號，網路上還有人癡癡的等待G8的出現:)...

G7 to G11
Canon Powershot G9
The G7 marked a major change in the G series. Previous G series models had featured a fast lens, Raw image format capture, and a tilt-and-swivel LCD. These were all considered hallmark features of the G series, but were removed or altered for the G7. Some of the major changes included:
Introduction of a lens with a minimum F number of 2.8, compared to 2.0 in other G series cameras. Although slower, this lens introduced improvements such as optical image stabilisation, a higher zoom range (6×), and a macro mode that would focus as close as 1 cm. The lens would also retract completely into the camera.
Change to a fixed LCD rather than a tilt-and-swivel model. The fixed LCD was larger (2.5" versus 2.0" on the G6) and increased the number of pixels by 75%.
Removal of RAW image format on G7, but returned for the G9, G10 and G11.
No infrared remote control.
Change from CompactFlash to SDHC card storage.
Black, mostly metal, body.
Many of the changes made allowed the G7 to be significantly slimmer than previous G series cameras (e.g., the thickness of the G7 is 4.25 cm while the G6 is 7.3 cm), making it more portable.
The decision to remove RAW shooting support was heavily criticized. DPReview stated that they were disappointed with the loss of RAW format[6], while Luminous Landscape stated that the removal of RAW meant that too many technical decisions had to be made while shooting instead of post-processing.[11] RAW support can be enabled on the G7 using a free firmware add-on[12].
The G9 was released in 2007. Among its features were restored RAW support, a larger LCD screen, and a 1/1.7" sensor rather than the 1/1.8" sensor on previous models[13], .
The G11, released in 2009, reintroduced the flip out and twist LCD.

雲爸太強了....
看來  雲爸  也是  CANON 的愛用者唷!!!

是啊~最近考慮要買G12
不過銀彈有限，我也想買Galaxy Tab
考慮很久的說...

話說!   Galaxy Tab上市了
可是我錯過了第一波送藍芽耳機
這樣讓我的敗家慾望降低了不少....

我對Powershot這一系列都還挺有信心的，畫質各方面還不錯，算是帶單眼外出時必備的隨身機，也是各種大小場合必定出動的，單眼可能放在家不想帶。感謝分享！
