If so, how do I do it? Hi Andrew, Firstly a disclaimer. The modification is not for the faint hearted, and requires competence with hacksaw, soldering iron, and #00 screwdriver. I provide this information for your entertainment only, and I will not be responsible for any damage or loss of warranty to your equipment. Attempt this at your own risk. The BP-50 can be used in four configurations with the EOS 1000FN / Rebel SII, with increasing levels of modification. 1) Grip Extender (with Tripod socket) Use a hacksaw to remove the battery connector on the BP-50. It will now fit nicely on the bottom of the EOS 1000FN. This is similar to the use of a GR-70, except that you also get an additional tripod socket on the BP-50. 2) Grip Extender with 4 AA or 2CR5 Power I soldered some wires to a dismanted 2CR5 battery shell and connected the other end to the switch of the BP-50, making sure of the correct polarity. Wire from cheap walkman-type headphones seems to work here. I use a battery of rechargable 1300mAh NiMH AA cells, and keep a spare 2CR5 in my camera bag. 3) Grip Extender with Power and Auxiliary release This requires dimantling the EOS 1000FN and soldering wires to the main shutter release circuit board. Sufficient length of the wires are led out through the battery compartment and soldered into the BP-50 release. 4) Grip Extender with Power, Auxiliary release and Remote socket I next drilled a hole in the BP-50 and installed a 2.5mm socket connected to the shutter release circuit. I can now use a RS60-E3 for remote shutter release. Dave Hersztein had done a similar thing for his GR10-L, see: You can see a little of the final result sitting atop my tripod at: If you are interested, e-mail me again and I can try to make and upload some more digital camera pictures showing the modified BP-50 in greater detail. I spent so much effort on the EOS 1000FN because it has a split-image viewfinder which I find so useful when focussing. Vive les Rebel IIs! Cheers Julian Loke
