Re: [情報] Tamron 即將推出 18-270mm VC ~~~
※ 引述《teajo87a ( 小王)》之銘言:
: TAMRON announces the development of the AF 18-270mm Di II VC
: AF 18-270mm F/3.5-6.3 Di II VC LD Aspherical (IF) Macro
: http://www.dpreview.com/news/0807/08073001Tamron18270.asp
: 這鏡頭 搭配 VC 防手振的機制 ... 乘 1.5 後是 27 ~ 405mm
: 乘 1.6 後是 28.8 ~ 432mm
: 比較:
: 18-200mm => 大約 11.1 倍光學變焦
: 18-250mm => 大約 13.8 倍光學變焦
: 18-270mm => 大約 15 倍光學變焦
: 現在的旅遊鏡 焦段愈來愈好用了 XD ~~ 看來 sigma 18-200mm OS 有對手了 ..
: 只是一直往高段變焦發展 為啥不往廣角端前進幾步 ... 可惜
: 若來支 16-200mm VC 不是更好 ... 保證大賣 ...呵呵
close focusing down to 0.49m (19.3 inches)
from the subject over the entire zoom range
全段微距,49公分最近對焦
The maximum magnification ratio of 1:3.54 at its 270mm telephoto end
270mm望遠端,最大放大倍率3.54
The light rays thus reach the image sensor within a defined circle
that assures high imaging performance and reduces light falloff.
減少曜光的特殊光線入射方式(?)
Thorough countermeasures, including advanced internal surface coatings,
prevent ghosting and flare

嘖,沒有重量是怎樣~~
但看這顆鏡頭的大小,感覺應該也不會太重~~
但有vc,應該也不可能跟a14一樣輕吧!!
不過,感覺上好像是顆可以期待的旅遊鏡。
只是不知道成象的可接受度如何~~
如果價格在一萬五上下,我應該會毫不考慮就敗了吧!!
本來想買a14,不過現在看來,應該可以再等等。
