Okay, during a holiday trip the problem got even more interesting: after a few more erratic faint-screen-sessions (yet taking pix fine) it now refuses to do anything, with only a faint blinking of the film transport symbol. Battery is fine. The most challenging part is that I have a film stuck inside, infrared no less....no way I can trust a Canon repair-shop with that. Hence the most important question: Can I pull the film out with force? (note that HIE is way stronger than ordinary film, so that would be the least problem....I just need to be sure that there isn't some kind of worm-gear inside, preventing any motion of the film take-up spool....direct drive would be best of course, without any gears between motor and spool) PS: anyone else ever shot IR on and in Alcatraz?....;)) In particular fisheye or panorama? (think I shot a nice one through the hole in the door on the far left (up a narrow stairs on the outside), looking into the recreation yard: http://www.alcatrazhistory.com/exterior.jpg (thank god I had a never failing Horizon 202 with me as well) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand <[EMAIL PROTECTED]> [note: 'a-one' & 'en-el'!] * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
