<FONT SIZE=3>采用延长管或皮腔是会减弱光线，应增加曝光补偿，称为曝光系数Exposure Factor，这是根据以下的方程式计算：<br><br>
<IMG src="formula01.PNG" WIDTH=110 HEIGHT=24><br><br>
f=延长度   F=镜头焦距  M=成像比 可用曝光系数的对数作为补偿曝光的级数。<br><br>
在采用延长管或皮腔时，以测光表及灰咭测光再加补偿比镜后测光较为正确。<br><br>
微距摄影除了实用性外，在拍摄自然题材中的花卉，昆虫等是必要的技巧。这种拍摄是需要极大的耐性，相当的体力，特别是按快门前后的动作需要百份百的整体控制。

<TD WIDTH="25%" VALIGN="TOP"><P><FONT COLOR="#FF0000" SIZE=3>佳能的专门微距镜头是多年前的FD系列镜头之一，EOS面世后已停产了。由于使这些镜头可以装在EOS机身，是有EOS-FD的接环供应。近年佳能集中于高质素的长焦微距镜头，例如EF180mm f3.5L Macro USM。</FONT></P>
