LENSPEN 是專門用來清潔鏡頭的潔鏡筆,
看到有人說好用, 就去買來試試看, 果然還滿好用的.
以畫圓圈的方式擦拭鏡片表面, 就可以擦得很乾淨.
一支約 250~300, 聽說有滿多仿冒品, 在購買時需注意.

CCD進塵

去澳門回來後發現某些照片中間上面都有一個小暗點,
把光圈調最小, 對天空試拍幾張, 暗點很明顯, 確定是 CCD 進塵,
應該進塵很久了, 因為大部份時間都用 f1.4 的鏡頭, 所以看不出來.
進塵處理:
用反光鏡鎖定功能, 按下快門, CCD 面朝下, 用氣球噴一噴, 再關掉相機電源(反光鏡會回復)
如此應該可以吹掉大部份的微塵, 若還是不行, 可能就需要用果凍筆之類的工具.
