Footnotes:
1 Extension Tube 25 II is furthermore not compatible at wide angle settings with EF 16-35mm F2.8L USM, EF 17-40mm F4L USM, EF 20-35mm F3.5-4.5 USM, EF 24-70mm F2.8L USM, EF 24-105mm F4L IS USM, EF 28-300mm F3.5-5.6L IS USM, EF-S 10-22mm F3.5-4.5 USM, EF-S 17-85mm F4-5.6 IS USM, EF-S 18-55mm F3.5-5.6 II USM and EF-S 18-55mm F3.5-5.6 II.
Canon also does not recommend the use with EF-S 10-22mm F3.5-4.5 USM and EF-S 17-55mm F2.8 IS USM at near tele end, since it radically reduces working distance (just take care about your front lens element ...)
2 When using close-up lenses you can step-up the filter thread, but cannot step-down (the diameter of the close-up lens must be equal to or larger than the filter thread of the lens).
