Many monts ago, I ask Canon U.S.A. some questions

about automatic flash reduction system of the Rebel XS.

Canon U.S.A. said that flash reduction system only

works in P, Tv and Av modes.

Thanks Bob, I want to buy the Canon macro

conveter, because my Canon A-1 doesn't

have TTL flash system. Thank you very much.

I read in Canon EOS FAQ by Bob Atkins that the Canon FD-EOS macro converter is not recomended with Canon EOS bodies, that don't have interchangeable focusing screens, because the exposure readings are not accurate. I have an ELAN II and a REBEL XS and I want to buy the Macro converter to use it with my Macros FD 50/3.5 and FD 100/4. Do TTL flash systems of these cameras work well with the macro converter? Is there a constant factor of exposure compensation for ambient light, when the camera meter is used, or the exposure compensation is variable according to intensity of ambient light? Is there any risk of damage, if these cameras are used with the Canon macro converter (which is not recomended to be used with these cameras)? Thank you very much. B. Riber
