I was very surprised when my modified extension tube, which worked good with the EOS50, prevented the EOS30 from firing. I discovered that isolating the contacts (with sticky tape for example) restored the firing capabilities. That is by far a beter method than phisically removing part of one of the 'wings' (or how you call it) on the mount that enables the manual lens, but disables the electronic communication. (For TC's and extension tubes, that's a real compromise) Regards, Gerard. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
