		<description><![CDATA[When selecting a dslr lens, what maximum aperture do I need? For beginner, one important must know before selecting an aperture. You have to know that number of aperture (or aperture value, f) and the size of aperture is inverse. The aperture value normally show as &#8220;f/5.6&#8243;, or &#8220;f-5.6&#8243;, or sometimes like &#8220;1 : 5.6&#8243;. [...]]]></description>

The aperture adjusts the size of the opening through which light passes to the image sensor. The aperture can be opened up to let in more light or closed (stopped down) to let in less.
