The overall performance of Sigma 10-20 mm and Tamron 12-24mm, Which one is the best?????

Thank you very much for your advice

[rickwok]

Tamron 應是11-18mm, 12-24mm是Tokina

我只用過sigma10-20，非常好用。

Sigma 10-20 is selling around $3600 and Tokina 12-24 is selling around $3480 兩者差不多, 係睇你鍾意wide 多2mm (Sigma) 定係想要恆定光圈(F4) (Tokina)

stephen csw,

remember 2mm in ultra wide angle means alot, unlike the tele end 2mm is nothing.

10mm x 1.6 (1.5)= 16mm (15 mm)

12mm x 1.6 (1.5)= 19.2 mm ( 18mm)

Which make a big differences, however, 12-24 is for full frame you can use it in full frame later if you want.

12-24 係 DX 鏡...

[入門漢]

應該話，3支都唔係全片幅，即係所謂DX鏡。

[平凡的地夫]

lambertnh, 12-24又FF的話 可能佢搞錯左sigma o個一枝

[rickwok]

同意2mm的差別好大，所以我買sigma時從來都無考慮過tokina

[kwok42003]

聞說話sigma這支鏡兩則有對焦不準的問題，是真確的碼？

[MN56]

1. Sigma 比Tokina wide 2mm, Tokina又比Sigma tele 4mm；

2. Sigma 最大F5.6又非恆定，Tokina F4恆定，唔係話F4比F5.6既優勢大好多，而係恆定光圈既鏡一定係用料造工比非恆定會好；

3. Sigma鏡出既色唔及得Tokina (我接受唔到Sigma又黃又灰既色)！
