Canon Powershot SX30 IS評細測試報告

最近有好多朋友好似對部SX30 Is有興趣,小弟第一次響到post試機報告,雖然測試方法並唔專業,但希望對大家有D幫助。

緣起:
九月頭外國相機展PhotoKina 2010中,Canon公布一部35倍光學變焦既新機,名叫[color=Red]Powershot SX30 IS[/color],初時對呢部機既睇法:咁高倍數,zoom盡都唔方好啦;睇佢的規格,1400萬像素,24mm至840mm等於135底片格式焦距,4.5級光學防手震,扭mon,高清拍片(1280x720 720p)等等,除左35倍外,都無乜特別引起我注意。但家人就對此機有興趣,就買部送比佢地啦,但送之前就拎黎做個測試。

在測試之前,先比大家睇下部機係怎樣的:
此機賣$3350,響"相機發燒"店鋪購買,送卡送電送mon貼,價錢我覺得可以接受。(但質數呢?)

[u]Zoom至840mm的長度[/u]

[img]http://images4.fotop.net/albums4/pitarhk/SX30_IS_test/IMG_0726.jpg[/img]


睇完外型,可能會覺得好巨型,但個尺寸只有110mm(長)x125mm(闊)x90mm(高),重量大約600g,比起D70s+30mm f/1.8還要細要輕!

好啦!試機既時間:
(為公平起見,以下相片為原相,並無切裁誇大倍數。)

先試最為人注意的倍數,究竟35倍威力何在?以前玩過10倍既DC,Zoom後唔覺得好遠,尤其影雀可以當風景DC用。

測試地點:米埔
測試日期:2010/09/23 陰
測試方法:手持(開IS)

[u]24mm[/u]

[img]http://images4.fotop.net/albums4/pitarhk/SX30_IS_test/IMG_0050.jpg[/img]

[u]100mm[/u]

[u]400mm[/u]

[img]http://images4.fotop.net/albums4/pitarhk/SX30_IS_test/IMG_0052.jpg[/img]

[u]840mm[/u]

[img]http://images4.fotop.net/albums4/pitarhk/SX30_IS_test/IMG_0053.jpg[/img]

此項測試證實比現時任何高倍數DC還要遠,但也發現它的840mm等於Nikon D70s+300mm+1.4x (630mm)既成像距離一樣!

以下係單筒與SX30 IS比較
單筒為: Swarovski STS-80HD + 30x + Canon PowerShot S90

接住,大家會關心雜訊方面,此機用上1/2.3”既CCD感光元件,有效像素為1400萬像素,理論上雜訊會比使用1/1.7” 1000萬像素的S90還要利害!

測試地點:銅鑼灣
測試日期:2010/09/23
測試方法:腳架,使用24mm焦距(關IS)
白平衡:鎢絲燈

測試後,發現可接受為ISO 200,由ISO 400開始雜訊會較明顯。



至於鏡頭解像度在最遠的情況下是否可以保持清晰。(以往高倍數DC在最遠時會較模糊)
此機最遠端時光圈會由f/2.7縮小到f/5.8,所以測試方法由f/5.8~8。

測試地點:銅鑼灣
測試日期:2010/09/23
測試方法:腳架使用840mm焦距(關IS)
白平衡:鎢絲燈

由相中的''北角''為測試解像度,測試中央及邊緣解像度:

[img]http://images4.fotop.net/albums4/pitarhk/SX30_IS_test/IMG_0228_2.jpg[/img]

[u]f/5.8[/u]

(邊緣)

[u]f/6.3[/u]
(中央)

(邊緣)

[u]f/7.1[/u]
(中央)
[img]http://images4.fotop.net/albums4/pitarhk/SX30_IS_test/IMG_0230.jpg[/img]
(邊緣)
[img]http://images4.fotop.net/albums4/pitarhk/SX30_IS_test/IMG_0230_1.jpg[/img]

[u]f/8[/u]
(中央)

(邊緣)
[img]http://images4.fotop.net/albums4/pitarhk/SX30_IS_test/IMG_0231_1.jpg[/img]

測試後,覺得以f/6.3在遠端時解像度比較好。


至於無論怎麼鏡頭,都會有俗稱''紫邊''問題,尤其響黑白高反差位置,較為明顯。

相機的影相既測試就暫時到呢到,接著就係拍片既測試:

影片功能中,不得不提可以在任何影相模式中按動拍片掣拍片,不須經過影片模式進行,對於影相同拍片極為方便。其影片中解像度最高只有1280x720 即720p高清格式,未能以全高清1080p拍攝。

測試地點:西貢碼頭
測試日期:2010/09/23 陰
測試方法:手持使用840mm焦距(開IS)

[url]http://www.youtube.com/watch?v=39o5x0Mu14A[/url]

片中測試,由於光度及背景問題,不時發現IS間歇出現移動,影響拍片質數,而且背景沒有明顯反差,出現短暫對焦失效問題,在IS間歇出現移動中,解決方法就係把IS關掉及使用腳架拍攝。

而操作上,拍片是設有實時變焦,方便拍攝移動中的黑鳶;而且變焦控制桿亦發現可提供快/慢速度的變焦速度!(註:是 變焦 並不是 對焦 )


總結:經過第一日既測試,不得不發現此機帶出一種驚喜的心情,以怪獸級變焦倍數得出有一定質數既相片,而且此機玩樂性很高,其中一項為模型效果,將風景相變成一張模型世界既相;拍攝上,此機有兩種觀景模式,1‧眼平觀景器(亦稱電子觀景器) 2‧LCD觀景器,在普通拍攝上,使用LCD mon很方便,上下左右反轉都得,而想拍攝飛行雀鳥,建議使用眼平觀景器,但也注意,由於眼平觀景器不是以反光鏡來觀看,而是電子顯示器,會出時快門時滯問題,換然之,當按下快門時,佢會以大約0.5秒時間才進行拍攝,此舉不利拍攝飛行中雀鳥。而電池方面,初時以為磚頭那麼大的電池以為部機會很耗電,但是玩一整日,顯示電量還是滿的(係咪個電量計壞呢XD),即係出去玩,一粒電就夠!(當然都會帶定後備電....<-被打)要注意鏡頭部份係塑膠製造,同以往型號有不同,所以使用時要小心,而鏡頭可以裝上52mm濾鏡,亦都可以加上增倍鏡或魚眼鏡。總括而且,我推薦呢部相機。

測試非常詳細,多謝你,紅耳鵯長者若想買相機,我會推薦他們先看你的報告好過聽售貨員吹水買錯相機。

tbob 25/09/2010 08:01

Pitarhk,

Thanks for posting the great series of shots,I think this maybe the best HK$3580 I have spent. Besides the camera I got a camerabag, card reader, extra battery, gorilla pod and LCD protector all for that price.

Thanks for the detailed report.  Very tempting. 3551em012445

It is worth reading Page 59 of the manual, I didn't before shooting. If you are using the Digital Tele Converter don't use the following recording pixel settings  L, M1 or W as Canon say the picture will deteriorate, you can tell if you are in the wrong setting as the Digital Tele-converter number 1.7x or 2.1x will appear in Blue
