... I am a bit confused. Shooting with Canon Digitel XT. Lens is a Sigma70-300F4-5.6 DG Macro. Shooting regular is fine. If I get within about 2-3 ft and try to take a shot I cannot do it. Shutter will not release and the flash just keeps lighting but dosn't flash and take the shot. Am I out of focus here and thats the reason or am I too close. I am confused, but I am sure there is a simple explanation for this. thanks for your input.

Looking at the sigma web page, the minimum focusing distance for that lens in "normal" mode is 59.1 inches. In "Macro" mode it is 37.4 inches. Both of those are under the 2-3 feet you are listing.

That is probably why. At less than the minimum focus distance it will try to focus but will not succeed and then I don't believe the shutter will release.

You do have it set to macro when you are using this close? I have the same lens and it works fine on my Rebel XT.
