我想問下其實焦距同埋zoom 係咪成正比既呢?
點解佢部野咁長焦...得3xzoom...點打雀呀?!

[sevensister]

幾多倍係計 由最 WIDE 到最 TELE 有幾多倍差別喔....

呢部野最低 (1x) 450mm 都已比 panasonic FZ1 (12x) 420mm 長...

咁你話(3x)成千幾 mm 夠唔夠雀喇 ? :)

打漏左個"打"字 tim...:)

herofung, 唔駛急, 慢慢等吧, 因為 C740 已經響台灣出左兩個月, C750 就岩岩響日本出左, 我諗大概於 8-9 月香港來貨哪.

變焦用光學 10X 好了, 千祈唔好用數碼變焦, 因為相片的成象會破壞架.

如果覺得10X都唔夠, 不如趁而家買 Olympus B300 啦, 增距 1.7X 喎, C750/ C740 咪變左 17X 囉, 聽講平左好多, 1000蚊有找. 或者輕一點就買 Olympus TC-17, 都係 1.7X, 其實都係一樣, 不過可能較貴.

如果 C750 畫質係有保証, 我會多買一部 C750 給家人用, 10X 係幾方便, 不過 C730 真係唔好買, 因為我見過D相, 色散紫邊好嚴重.

I am new to DC and I have a Olympus C-5050Zoom, it has only 3倍光學變焦.....so if I buy a Olympus B300 or Olympus TC-17 (增距 1.7X) as you mentioned, 咁真係幾多倍光學變焦呢 together with my Olympus C-5050Zoom 3倍光學變焦?

Actually I want to add a lens to make 景深效果. would that work? I am sorry as I have no idea about all this.

[亞典波羅]

what 兄, 5050 得3 倍變焦, 加 B300, 即係 3 X 1.7 = 5.1 倍囉 (178.5MM 咋)

其實 1.7 X 只係乘數來.

又講講其他野先, 5050 鏡頭係 35MM, 有三倍變焦, 條數係咁:
1) 3 倍變焦時: 35MM X 3 = 105 MM
2) 加 B300/ TC-17: 即係 35MM X 3 X 1.7 = 178.5MM 啦.

所以 C750/ C740 就犀利囉, 鏡頭 38MM, 有 10 倍, 即係
1) 10 倍變焦時: 38MM X 10 = 380MM
2) 用埋 B300/ TC-17, 即係變左 38MM X 10 X 1.7 = 646MM

不過C740/ C750 畫質一定要好, 長焦先有用, 如果唔係買黎都冇用.

其實加左 B300 都有加強淺景深架, 當然冇單鏡機的鏡頭咁正斗哪.

Thanks very much for your detailed explaination, you are most helpful. :)

By the way, if I want to add a lens to have 淺景深 but more than 1.7X, which lens would you suggest? and how much please?

Thanks a million!

[亞典波羅]

what 兄, 唔駛諗其他了, 因為其他鏡有色散紫邊, 但只有呢隻鏡係完全無問題, 買呢隻鏡包滿意, 買其他鏡會後悔.

[what]

亞典波羅兄, which one are you suggesting? Olympus B300 or Olympus TC-17? Umm....does it do a good job for 淺景深? and how much are they? Please advise!

[亞典波羅]

兩個鏡都一樣, 不過聽聞 TC-17 比 B300 輕, 但 B300 畫質已很冇得彈, 而且又平左, 買 B300 啦.

用左增距鏡 B300 的確有加強淺景深, 係 WORK 的......
