Tamron SP AF 17-50 F/2.8 XR Di II LD Aspherical [IF] (A16)（已停產）

good
color sharp

to noisy while focusing

pretty good

恆定2.8大光圈，景深一流，價錢平

對焦速度一般，暗位自動對焦特別困難

本人用的是A16 II + D80 當KIT 鏡用，效果不錯

i used this new lens (build in motor),a week,i found that it have a problem,sometimes,my DSLR(Nikon D70s)can`t sence the len,and when i press shutter button,the shutter dosen`t move,i use sigma 70--300 DG APO,nikon 50mm 1.8 haven`t this problem............any body have this problem too??

最主要優點是:恆定2.8,小巧,價錢平

最主要缺點:最廣角時的變形(但實有,可以接受),色彩層次一般

這支鏡之所以在市場上大勝,都只係兩個字:平衡
包括:體積上的平衡,價錢上的平衡,用料上的平衡,成像上的平衡,市場上的平衡......都較其他同焦段恆定變焦鏡做得好.

compare with non build in motor,the new model is more quiet and a little bit fast of focus,i had use the old model A16 from my friend,the new one give me a very good 質感,yesterday i bought in wing XXXX $27XX,it is very cost i wait it for long long time!!use D70s with it feel very enough.

the focus ring a bit tight,maybe because it is new......
no macro,if have macro1:2, 3200 also very cost!!!!

tomorrow i`ll bring it to victory park to test 成像質素,so far i like this len very much.
i`ll 推介此鏡頭給朋友.

Sharp, colourful
New lens with built-in motor which is very quiet, now a/v in Man Shing

Slightly slow in AF

Quality/performance great!
