aaron_lam Posted December 14, 2004 Share Posted December 14, 2004 Does the lens expand when focusing for this lens? Or does it same the same length throughout focus range? Link to comment Share on other sites More sharing options...

Otherwise you could try the Canon camera museum lens section. All the best Damian Link to comment Share on other sites More sharing options...
fergus kane Posted December 14, 2004 Share Posted December 14, 2004 Lens length on the 100mm is always constant. Focusing is internal. Link to comment Share on other sites More sharing options...
artofseeing Posted December 14, 2004 Share Posted December 14, 2004 As others have said. No, the lens does not expand. The lens is a fantastic optic and handles very well. I use one and it is highly recommended. Link to comment Share on other sites More sharing options...
eos 10 fan Posted December 15, 2004 Share Posted December 15, 2004 The original 100mm Macro non USM changes length, <br> but the newer USM version does not. <p> -- Link to comment Share on other sites More sharing options...
eosdoc Posted December 15, 2004 Share Posted December 15, 2004 Is the question about the length of the barrel? Or the focal length of the optical elements of the lens? <P> To the second question, no. The EF 100mm macro does not same the same length throughout focus range. <P> See: <a href= http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=003z4N >http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=003z4N</a> Link to comment Share on other sites More sharing options...
