Hi guys
I will appreciate if somebody can help me on this. I got an Extension Tube EF12 II, and I intend to use with my lens Canon EF 100mm f/2.8 USM Macro, now, when I mounted the extension tube together with the lens, for apperture it shows F00, what doesn that mean? how can I change the apperture when use the extension tube?
Thanks |

| I assume it's a genuine canon one and not a cheap one? The cheap ones don't have the electrical connectors in so you can't change the aperture. If it's a canon one make sure the connectors are clean. If it still doesn't work it sounds like it's faulty :( |
