評價:
I borrowed Tamron A16 from friend, then wanted to buy one, but cannot find any stock in the market. So, I bought Sigma of similar specifications. The picture quality is good, with very convenient F2.8 on whole 18 - 50 mm. Price is HK$ 400 higher than that of Tamron, but it is made in Japan. Though I cannot compare both lens on the same time, but I do not find any area that Sigma is inferior to Tamron A16
