I have a set of Kenko extension tubes to be used with my EF/EOS lenses. These tubes do have EF electronics coupling so the camera will at least try to focus automatically. These same tubes are available under different brands. text/html 2023-02-22T06:32:41+00:00 Anonymous (anonymous@undisclosed.example.com) https://heikkisiltala.net/wiki/en/photography/camera_stuff/cameras_lenses_and_else?rev=1677047561&do=diff Camera and lenses are not all you need Written in 2005, latest update 2010.

Although being all plastic Sigma EF-500 DG Super worked well and had plenty of options to play with.
