跟50D kit set 買邊知好EF-S 17-85mm f/4-5.6 IS USM or EFS 18-200mm 18-200 IS?買18-200mm 的價錢補D到買至17-40L f4,不過支EF 17-40L無貨.

我見EF-S 17-85mm 評分不太好. 一話淨body 配知 sigma 18-200 ex 再加17-40L f4.

18-200 for daily use very good

EF 17-40L not really useful for 50D as not wide enough

本人來說, C記支18-200 真係麻麻, 當方便鏡來說又不是最方便, 200mm時
不知是不是我錯覺, 我覺得它沒有200, 最多得180, 影出來的相D色又好似好
淡, 價錢又不是平, 如果想一支走天涯, 不如諗下支龍仔18-270 焦段起碼長多成百先, 又平D,不過對焦會慢D, 又可再諗下支 色盲 18-250 新o野, 但未到應快有了, 可試下先, 但我直覺覺得它會幾正, 我都等待中 CC .

"我覺得它沒有200, 最多得180" <==== ARE U SURE?
I just compared it with EF70-200/F2.8 @ infinity with 200mm, not much different wor

[Thomas1]

一定有200.

canon 會做支寫有200, 實際只有180,俾人吋!!!??
有可能嗎?

[Obi-Wan]

Thomas1, yes!

Nikon 支 18-200mm 都出現過如此疑惑

200mm end compare with 200mm 定焦

話唔足 200mm

[Obi-Wan]

ALL 200 mm lenses should have the same COVERAGE OF FIELD on the same sensor WHEN FOCUSED on infinity.

When they are focused to a CLOSER distance, they may have different coverages. In general, a lens with internal focusing mechanism will show a SMALLER coverage than a lens with front elements extended mechanism.

u can prove this easily if u have many lenses of the same focal length

180~200其實係有分別的......只是你的object係近定遠而已

你用200mm同180mm影近野一定冇太大分別;
相反用200mm同180mm影遠野,就有一定的分別,但放大的情況一定唔太明顯了......

如果仍然看不到那些分別的話,那可能要驗眼了.......

夠膽講句......放大率愈高的天涯鏡,成像同色水都預了一定較L鏡及其他普通變焦鏡遜色了......買得它,就要預了它有咁既不足,否則就唔好揀它,反正它根本不是聞相人士那杯荼......

不過係窮人之寶,好過無囉

我都曾經試過用EFS 18-200mm 既200mm端同支定焦200mm 2.8比較, 焦距上當時唔覺有好大分別.

ef 24-105 f4 is usm is good

I am using the kit lens EF-S 17-85mm too...but...
before I bought it...I am thinking it doesn't matter as a new player....
but after two weeks...it is not "enough" for me as I always used it at home(indoor) to take photos
better to have F2.8....which no need to push the ISO...

For my short experience, the QUESTIONS to be think about...
1. When do you always use your DSLR? (indoor/outdoor)
2. What are you going to take mostly? (nature/ people/ insects/ birds)
3. budget?

they are all affect basically the mm and F....
I think you better buy the body and better lens (depend on the questions above)
p.s. i want to have 70-200 2.8 IS USM and 24-70 2.8 L IS USM too
but...think deeply...i always take my little daugther so i bought the second one 1st....not enough $ ma

各位高手..........我都係新手＇
以前用450D+tamron A20(28-300mm).因為比我家姐用‧自己買咗50D kit.
(18-200mm is).雖然焦距有分別.但比多啲時间操吓支鏡.其實都係知好鏡囉!
同埋睇吓你個人需要啲也焦距.影啲也!
因我在Canada工作時间長.我最近回港都買咗支Sigma 150-500mm os.水貨
外地...地大..景多..長啲焦距有用啲!
所以師兄..........視乎你個人影也嘢多!
啲架歺夠用便算...............
以上個人愚見............謝謝!
