rainer_t Posted February 23, 2009 Share Posted February 23, 2009 <p>The 430ex supports E-TTL for newer cameras and TTL for older cameras. You shouldn't have any problems with it on your EOS3.</p> Link to comment Share on other sites More sharing options...
bjscharp Posted February 23, 2009 Share Posted February 23, 2009 EOS 3 supports E-TTL, so all will be well. Only thing missing is from the EOS 3 is E-TTL II support (introduced in 2004, while the EOS 3 is from 1998), so if you have lenses that pass on distance information, it won't be passed on by the camera to the flash. Shouldn't matter though. Link to comment Share on other sites More sharing options...
philip_wilson Posted February 23, 2009 Share Posted February 23, 2009 <p>My EOS 3 works well with the 550 EX which post dates it so i am sure you will jhave no problem with the 430EX - as people have pointed out you will lose functionality.</p> Link to comment Share on other sites More sharing options...
hjoseph7 Posted February 23, 2009 Share Posted February 23, 2009 <p>The EOS3 was specifically built to go hand in hand with the 550EX, so the 430EX should work fine.</p> Link to comment Share on other sites More sharing options...
picturesque Posted February 23, 2009 Share Posted February 23, 2009 <p>But since the EOS 3 uses the original ETTL, be aware that flash exposure is focus point biased--the area around the active focus point is primary--which makes focus/recompose less useful. If you haven't used ETTL with the EOS 3 much, I'd maybe build in a bit of flash exposure latitude by using 1/3 or 2/3 stop lower ISO than rated for the film you use.</p> Link to comment Share on other sites More sharing options...
fred_monsone Posted February 23, 2009 Author Share Posted February 23, 2009 <p>Thanks everyone. It did indeed work well so I'm glad both pieces are still in full working order!</p> Link to comment Share on other sites More sharing options...
