It&#39;s compatible with my 550d, but the pictures are blurry. So I was checking the lens out and found out that the area from where it hooks up to the camera, the len&#39;s glass is blurry. Is there any way to clean it? It&#39;s blurry from the inside.<br /><br /> shahbazkhw Photography, Digital Imaging &amp; Video Sun, 19 Dec 2010 08:46:13 +0800
