Canon 50D with EF-S 17-85 lens.
To do some close up photography I recently purchased a Canon EF25 II Extension Tube to use in conjunction with the above.
However, when it is mounted with the lens I cannot achieve focus on anything, at any distance, at any focal length !!
I have tried focussing Manually, as well as AF ( and even switched off Image Stabilization in desperation).
I'm sure the lens and extension tube are correctly mounted.
AM I MISSING SOMETHING HERE ?
Any advice would be appreciated as I'm tearing out what little hair I have left over this.
Thanks
