枝KIT鏡咁貴, 同副廠的標準鏡比較, 算唔算好呢??

1.Sigma 17-70 f2.8-4.5 DC MACRO
2.Sigma 18-50 f.2.8
3.Tamron 28-75 f.2.8

I have (A) 18-55 (kit of 350D), (B) 17-85IS, (C) 18-200 sigma
test with flash

sharpness @17-20: B = A > C
sharpness @>20mm: B > A (a little bit) > C
sharpness @>50mm: B > A = C

chromatic aberration @wide C (worst) > B > A (best)

the original 18-55 (kit of 350D) is a good & light general purpose lens (highly recommanded)

I've not tried zoom lens with f2.8 so can't compare

睇你影物多啦
三支都唔同法

感覺不錯啊
我用 350D, 就只有 17-85mm 及 50mm f1.4
我通常用 17-85 一鏡走天涯

17-85 IS USM 的外國review 話佢有好大的紫邊問題, 而且邊緣鬆散, 解像力又比唔上同級...踩到好盡..

rickymak1406兄, 你有冇呢o的問題呢??


只係話佢好過 350D 的KIT鏡, 同埋有IS做selling point, 可以叫"全面"
不過$4000 就唔太合理, 性格比太低...

17-85 IS USM 有好大的紫邊問題, but still usable (u can easily fix it with PS raw input or paintshop pro, I use a macro in paintshop pro to fix all photos taken with the 17-85 at the wide angle)

the standard 18-55 has a much higher performance/price ratio than the 17-85IS

The 17-85 quality is only worth $2000, if the 18-55 worth $500.

BUT the 17-85IS & the Sigma 18-200 are still the ideal lens for travelling
