見到騰龍支新天涯鏡comment 好好，有wide 有tele有超強防震，好似好方便，好吸引。我依家無長鏡，現有兩支鏡：
1. Sigma 10-20mm 超wide，好好用，風影一流
2. Sigma 18-50 F/2.8，大光圈，實用焦距

我有少少想法，2個方案：

A
Sigma 10-20mm + Tamron AF18-270mm + Nikon 50mm F/1.8
因有定焦玩大光圈而且超平，定焦影人一定好正，加支長焦距防震天涯鏡，呢個方案應該好方便，還有咁玩法價錢應該唔太貴(放手上的sigma 18-50mm F/2.8


B
Sigma 10-20mm + Sigma 18-50mm F/2.8 + Tamron 18-270mm
呢個方案就真接加支龍仔天涯鏡，但有少少疑慮，怕會因為有支Tamron 18-270mm光圈雖然細過支Sigma 18-50mm，但因為有防震，所以成像都唔問題而懶用支Sigma 18-55mm大光圈。

大家有什麼意見？A or B比較吸引？

Vibration Protection on 18-270 is different from actual sharpness you can get from 50 1.8. the Former can ensure you don't get burry pictures because of your hand shake, while the latter gives you real optical quality (higher resolution by MTF) which should far better than the 18-270 (except at its optimal range and aperture).

Overall, I think 18-270 is good for travelling when you don't want to carry heavy, the 50 1.8 is good for portrait photos you do with children or girls.
