星際某鋪頭買支新Sigma鏡，但响鋪頭內睇左兩支lens都係多塵，sale哥哥話Sigma 廠鏡係會有d塵，請問c hing係咪有咁既情形呢？佢叫我試映過，需然放大唔覺[ 可能我唔識試 ]，心理關係後來我都無買到，因我屋企有支Sigma 30mm 都係呢度買，買既時間係無塵，究竟係咪我上次買鏡好彩？？又或者Sigma原廠係咁呢？？有無c hing有經驗？？

I went with my friend @MK a few days ago to test & buy a Sigma 50/1.4. The lens did not have ANY dust particles inside even after 5 minutes watching. The 星際 shop 昆 u.

I am also considering the Sigma 50/1.4.
Want to find out if you have any advise for me ?
What is your opinion about this lens ?
What is the price range ? Kind of worried about the
autofocus part of it.

Best regards,
William

有塵唔好買,買新鏡要有要求.
準焦無塵

我買既時候都幾失望，1]相差一星期貴$300，2]考慮後買鏡有塵.........失望！thanks Thomas1 ching~
