點睇? 底嗎? 質素好嗎?
指教吓! 都唔知點揀?

我無呢枝鏡頭，但它本身是與kit lens同級的鏡，價錢一定平，但質素只能是一般過一般。如果你有kit lens，對質素沒有太大要求，又要平平地玩到200mm，對kit lens的膠感又接受得來，又要支鏡超輕，55-200mm應該會是你的選擇。

或者可以到這裡比較一下：

You could also look at the Sigma 55 - 200mm, this is much cheaper than the Canon's (cost around $1K) and the build is more solid than the Canon's

For manual focus, Canon's do not offer a proper manual focus ring.
