請問這部機與一般之數碼相機有什麼分別呢　？
什麼叫做 rangefinder ?
為什麼會賣成US$3000 ?

請勞指點.. . TKS!

依隻係連動測距相機，類似萊卡

[dnamc2]

可以配靚鏡頭

除了可以拍靚相..仲可以滿足虛榮心 :p

同意！如果可以DIY個 LEICA 個 M 系機殼上去就天下無敵!

實在知識貧乏, 什麼是連動測距相機 ?　除鏡頭外, 與傳統相機有什麼分別呢？Tks!!

rangefinder 係點,大摡好似d傻瓜機咁樣啦!即係取影是用上面個觀影器,影相就用鏡頭,好多DC都係咁樣o既,但rangefinder 就在中間位置有個疊影對焦功能o既,用慣左都好快好好用o架! 你話同傳統相機有乜分別? rangefinder 就以經係傳統相機啦!!!

[JT1129]

襯高興我又補充吓，rangefinder同SLR嘅分別係rangefinder相機沒有反光鏡，拍攝時只有釋放快門一個機械動作，SLR就會釋放快門同鎖上反光鏡兩個動作，產生的震動較大，對以前的低感光度菲林影響很大，所以rangefinder同SLR各有優點，前者亦成為一大主流及很多經典相機的依歸，如有錯漏，請勿見笑！

多謝各位解釋, 不過若果只有呢D唔同的地方, 我都係買返DSLR算, 呢部機貴成倍, 實在無麥野吸引到人.....

[Gowest]

咁既價錢點解唔正正經經買部leica m6玩下?錢多冇定駛?痴痴地

[JT1129]

無錯！Epson R-D1就係出畀D多錢到無地方使，攬住一大堆Leica mount靚鏡頭D人買的！

[老叟]

連動相機可換鏡頭有限,有D仲要加個view-finder上去先用得,仲有近距視覺差,好麻煩,相機勝在輕便,不過呢個優勢巳經被賓得*ist-DS奪得囉!!

as mentioned by brothers/sisters above, the biggest difference between SLR and RF is the focusing mechanism.

SLR focus by contrast detection of the actual image projected through the lens onto the focal plane; while RF employ a mechanism like how the surveyors measure distances on the field, condensed in the form factor of the size of a camera.

surfed the web, and found the following 2 good links explaning how they work, and their merits.

http://www.photozone.de/3Technology/camtec2.htm
http://licm.org.uk/livingImage/Rangefinder-Camera.html

In additions to these factual information, I quite like to share my personal experiences,

1. oppose to 老叟 hing's mentioning, RF actually give access to a wide range of very good quality glasses, e.g. if the body is Leica M mount compatible, you have a good choice of lens from Leica, Voigtlander, Konica and a lot of vintage screw mount lenses, focal length ranged from 15mm to 90mm. Agreed, there isn't much available for anything above 90mm, and most of the Leica could cost quite a little fortune. However the Voigtlander is a lot more price friendly.

2. since RF do not have a flipping mirror, there is virtually no camera shock, so I am fairly confident to shoot picture handheld at down to 1/8th second indoor or in dim light.

3. again, due to the lack of the flipping mirror, RF's shutter lag is extremely short, Leica M6's well known of 20 ms vs. Pentax *istD's 130 ms as measured by imaging-resource.com, which really help a lot in the attemp of capturing the "decisive moment".

4. RF is definitely smaller and lighter if comparing with SLR system of same build and optical quality. e.g. Leica M system should compare with the class of F5 or EOS 1 together with the matching pro-grade glasses. Its not fair to compare with systems not in the same league. Well, my M6+35mm F/1.4 is definitely more manageable than my EOS RT+24mF/2.8.

Below is a wavy review of the M6 I've found in photo.net,

Finally, don't take me wrong, I won't recommend brothers, sisters here to go get the R-D1, judged by the sample pictures, I think its not good enough yet. I just want to share my experiences and perhaps clarify some mis-conceptions about rangefinders. I am partially agree with 老叟 hing, RF is not good for macro photography, and as mentioned, there is no lens above 90mm, so may not be good for sports photography too.
