請問ching， kenko 1.4x 或者2x 效果怎樣？
聽聞對IQ有影響，到底影響有機大？如果有ching手頭有teleconverter（唔限制牌子）可唔可以post睇下有幾大分別？多謝！

我而家用Minolta 70-200/F4 ， Minolta 75-300/F4.5-5.6 想加 1.4x 或者2X teleconverter. 想ching們0俾di意見。

Image quality will be just OK. But the focusing speed will be much slower.

But you won't see a lot of difference in the computer. Only when you output it that you will see it.
