請問有無師兄用Sigma 30mm F1.4 EX DC HSM,好吾好用?有冇走焦?

I am using k-x.. I have bought pentax 50 mm F1.4 first.
After a few months, I have also bought Sigma 30mm F1.4.

Then I regret I have bought pentax 50mm F1.4 because Sigma 50mm does a better job for shooting portrait.
I found NO 走焦 and the image very clear and sharp. I wish I have not bought pentax 50mm 1.4. Not using it much now...

Used sigma 30/1.4 before. No problem with the lens at that time. (use FA31 now).

For range at 50, DA*55/1.4 would be another choice

Sigma成像一向比較Soft，但整體還是很好用。 室內拍照可以用大光圈幫助把人與背景分離。 不過短焦距拍人像會有一定的變形，稍微拉遠一點拍會好些。

Pentax的Pk 口似乎沒有HSM，不過對焦不慢，30mm在K-5上面等效於45mm，跟大公主焦段43mm接近，屬於標準鏡頭，構圖個人不是太熟悉，用著不如Da21方便，但是銳度全開都挺好，顔色沒有明顯偏黃，偶爾在室內有偏黃，我這裏有Sigma 30拍得片子，黑白居多 http://woobaopei.tuchong.com/tags/Sigma30
