(1) The noise at ISO 400 is unacceptable even at fast shutter speeds. The noise at ISO 200 is noticeable, and at ISO 100 it's detectable.

(2) In Continuous H, the Pro1 captured 8 images in 3.7 seconds, then continued to capture images at a rate of one every 3.5 seconds. The viewfinder blanks during Continuous H image capture, so you will be unable to follow a moving subject in this mode.
(3) Canon attached their L-series designation to this lens, and while it doesn't have quite the quality of the Canon EOS L-series lenses, you'll be pleased with the color and sharpness it produces.

(4) The zoom is operated by a ring on the lens barrel, a motorized fly-by-wire affair; there's a slight delay as you turn the ring before the focal length changes.

(5) Movement is nearly-continuous through the zoom range; I counted more than 30 steps between the wide angle and telephoto extremes, more than adequate for shot composition.

(6) There is only a slight amount of Chromatic Aberration (purple fringing) present in high-contrast areas at wide angle; it diminishes at the telephoto end of the zoom range.

(7) There is also noticeable barrel distortion at full wide angle and a bit of pin cushioning at the telephoto end of the zoom range.

(8) Unlike most of its PowerShot siblings, the Pro1 is not equipped with a focus-assist lamp. Although its low-light autofocus performance is remarkably effective at the wide angle end of the zoom range, it is less effective than the competitors that do include focus-assist.

(9) The zoom control is in a place familiar to SLR users, but I miss the responsiveness and precision that only a mechanical zoom control can offer; there was a slight delay using the Pro1's fly by wire control, and it frequently over-shot the desired focal length.

(10) Power is provided by Canon's BP-511, a 7.4v 1390mA lithium rechargeable pack. The Pro1 managed to capture an average of 200 shots before exhausting its battery, including a lot of time spent testing and exploring the camera's menu system. This same battery is used to power Canon's 10D and Digital Rebel dSLR's, routinely achieving 400 shots before exhaustion; I suspect that the Pro1's EVF and LCD are a greater drain, resulting in the lower shot capacity per charge. An extra BP-511 would be a very wise first purchase and is highly recommended. Your use of the internal flash, continuous-AF, and motorized zoom will determine battery life.

Image quality is always the bottom line, and the Pro1 provides few disappointments. As I've already discussed, there's some lens distortion at wide angle and telephoto, purple-fringing in high-contrast areas, and noise present at higher ISO's.

以上只上節錄有問題的地方，完整Review還要各朋友看完全文。

我完全同意.....

好在我冇買到~
好似買D70好D

呢次Canon真係老貓燒鬍啦…

有冇前輩可以用中文翻譯呢?小弟英文很水皮 >"<

終於有D老外講返D "人話" LA, 吾學九龍D電腦雜誌亂咁吹，托大腳，都吾知有冇摸過部機就話，對焦快...完美....大話連篇....

(1) Noise的問題在ISO400時是不能接受的，ISO200時是很明顯的，而在ISO100的情況下是察覺得到。
(2) 在連環快拍時，EVF是會完全油漆黑的，不能看到要拍攝的移動景物。
(3) 在Pro1上的L鏡並不能跟Canon EOS-L系列的鏡頭質數比較，不過在彩色及銳利度還是很好的。
(4) 當你轉動它電子變焦環作變焦時，有一點的延誤。
(5) 電子變焦環作變焦時是近乎無間斷的，有超過三十節的等級，由Tele至Wide。
(6) 在相片的高對比的地方有紫邊現像，但這問題會在變焦至Tele消失。
(7) 有相當明顯的畫面變形現象於全Wide時，另外在最Tele時有少許的枕頭現象。
(8) 沒有附助對焦燈，雖然其在暗光之下在用Wide對焦時能力相當好，但跟擁有附助對焦燈對手比較但有所不足。
(9) 電子變焦環雖然操作像極在SLR的，但其反應及預測度並不能跟用手動變焦環去操作相題並論。問題在於行動延誤及有時Zoom得過?\"龍"。
(10)耗電量頗大，電池在10D及300D上可拍攝400張，但在Pro1上只得200張，作者懷疑是EVF及LCD食得最多電，及另一個重要因數：電子變焦環。

謝謝前輩,大致上都明白了 ^^"

更正：

(1) Noise的問題在ISO400時是不能接受的，ISO200時是很明顯的，而在ISO100的情況下是察覺得到。
(2) 在連環快拍時，EVF是會完全油漆黑的，拍攝者並不能看到要拍攝的移動物件。
(3) 在Pro1上的所謂L鏡並不能跟Canon EOS-L鏡頭的質數作比較，不過在彩色及銳利度還是很好的。
(4) 當你轉動它電子變焦環作變焦時，有一點的延誤。
(5) 電子變焦環作變焦時是近乎無間斷的，所謂無間斷是由Tele至Wide內有超過三十節的等級。
(6) 在相片的高對比的地方有輕微的紫邊現像，但這問題會在變焦至Tele消失。
(7) 相片於全Wide拍攝時，有相當明顯的畫面變形現象；另外在最Tele時拍攝出來的相片有少許的枕頭現象。
(8) 沒有附助對焦燈，雖然在暗光之下在Zoom至最Wide對焦時，其能力相當好，但Pro1在這方面始終跟擁有附助對焦燈的對手輸蝕。
(9) 電子變焦環雖然在操作上模仿在SLR的手動變焦環，但其反應及預測度卻不能跟用手動變焦環的操作相題並論。問題在於Pro 1上的變焦環有行動延誤及Zoom得過?\"龍"的情況。
(10)Pro 1的耗電量頗大，電池在10D及300D上可拍攝400張，但在Pro 1上卻只可拍攝200張，懷疑是Pro 1的EVF及LCD食電太多，及另一個重要因數：電子變焦環的操作對耗電量相當有影響。
