https://community.usa.canon.com/t5/EF-RF-Lenses/the-EF500mm-f-4-5L/m-p/78772#M17008 I am looking for literature for an EF mount 500mm f/4.5L non IS. This is the original 500mm Canon lens, it does not have IS. It is a terrific lens with variable manual focus speed.

This is a popular super telephoto lens among sports photographers. By restricting the maximum aperture to f/4.5, a motor-driven 500mm lens weighing only 3kg is realized. High picture quality from maximum aperture is realized by an optical system incorporating artificial crystal fluorite and UD (Ultra-low Dispersion) glass lens elements(2nd &amp; 4th), which eliminate chromatic aberrations. High-speed and silent AF with full-time manual focusing, focus-preset mechanism and power manual focusing sensitivity control, are ensured by a ring USM(Ultrasonic Motor) and inner focusing system. Extenders EF1.4X and EF2X are compatible with this lens with manual focusing."</SPAN></P><P><SPAN>&nbsp;</SPAN></P><P><SPAN><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/4520iD0DBEAE4696F584C/image-size/original?v=mpbl-1&amp;px=-1" border="0" align="center" title="1.gif" alt="1.gif" /><BR /></SPAN></P><P><SPAN><IMG border="0" src="https://community.usa.canon.com/t5/image/serverpage/image-id/4522i5D7799839162D75A/image-size/original?v=mpbl-1&amp;px=-1" align="center" title="1.jpg" alt="1.jpg" /><BR /></SPAN></P><P><SPAN><SPAN>The&nbsp;</SPAN><STRONG>EF 500mm&nbsp;<SPAN>f</SPAN>/4.5L USM</STRONG><SPAN>&nbsp;is now discontinued. &nbsp;<img id="smileysad" class="emoticon emoticon-smileysad" src="https://community.usa.canon.com/i/smilies/16x16_smiley-sad.png" alt="Smiley Sad" title="Smiley Sad" /></SPAN></SPAN></P> Mon, 31 Mar 2014 13:08:58 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/the-EF500mm-f-4-5L/m-p/78994#M17009 ebiggs1 2014-03-31T13:08:58Z
