我是新手，今天買了minolta f300。當我用光圈先決，校到最大(f值小)光圈時，我想影大特寫，但往往對唔到焦。請問點解呢﹖我應該點做先致可以影到景深淺的大特寫呢﹖謝謝忙

用macro, 每部相機有最短焦距, 你看看 f300 要幾多mm, 太短的話就唔得呀

對唔到焦, 應該係同你個光圈冇咩關係...

仲有, 你指甚麼 "影到景深淺的大特寫呢", 你想影咩??? 現在差不多所有 dc, 都係影唔到淺景深的效果的, 請你看看個forum 其他post 先呀..

你係咁隊到架相機埋去，想影大特寫，其實已超過了其相機的有效對焦範圍，緊對唔到焦啦
你試下行返後ｄ，唔好行到咁埋，咁就一定對到焦了

at F2/F2.8
for close distance shots, in terms of depth of field the focussing range is quite small... that's why it's hard for the camera to auto focus.

for f300 minimum macro distance is 5.7 inches in front of lens

step back and zoom in more.

you can always crop the image afterwards to make it a 大特寫
