I have now added the images of the 600mm lens. More marks on the body, but the glass is perfect. #gallery-111-1 { margin: auto; } #gallery-111-1 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 33%; } #gallery-111-1 img { border: 2px solid #cfcfcf; } #gallery-111-1 .gallery-caption { margin-left: 0; } /* see gallery_shortcode() in wp-includes/media.php */ #hand #second #used

Update. Both lenses have now been sold. In an ungaurded moment I pressed  the Buy button on Ebay and bought myself a Canon 800mm F5.6 lens. Pulling power. I have always said I use the 600mm more than the 500mm and I expect the 800mm will be even more useful. It has 4 stops of IS and I have tried it out hand held. It works. I could never hold the 600m steady, it was just too heavy. Only leaves me with one problem. Paying for it. I need to sell my Canon EF 500mm f4 IS USM lens
