Re the 350D problem
The camera came up with error 99 every time I would try to shoot , tried everything ( remove battery , change card , phone dial-a-prayer ) and no joy , apparently not an uncommon problem .
Bit of a pain just got my 70-300 IS lens which has been great for wildlife shots , guess I could try it with the modded 300D and see how birds look in infrared
