Hello.

I've seen several postings about the choice of Canon or Sigma macro.

I sent a reply saying that the Canon was faster to focus and easier to use.

I've now found another difference. I have the Sigma 105mm macro and it works
with my EOS620 (35mm) and IX and IX7 (APS) bodies.
It will not work properly with my EOS350D. In several modes the camera does
not want to do anything other than show "ERR 99". In a few modes (this is
not consistent) the camera will le me take one shot before the "ERR 99" pops
up. In these cases the shot has actually been taken.

Anyone else found this problem with the EOS350D?

I know I might be able to have the lens re-chipped but I'm debating whether
to save the money and get the EF-S 60mm macro which sounds like a nice lens.

Regards,  Ian.
