Urgent Help

Hello all,

I ordered the Sigma 150mm Macro and the Canon MR14EX macro flash. when try to mount the flash on the lens it doesnt fit? Saw the following Macrolight adapters I am wondering which one should I but for that specific lens ie Canon 72C, 58C or 52C please advice?

I belive the adaptor you want is the 72 since the front thread on the sigma 150mm is 72m and the natural size of the ringflash is different. I am sure I have seen several photographers using this combo,

it should work without problems - both your cameras (listed) are crop sensor and so should be able to take the adaptor without losing image to vignetting on the lens - with full frame cameras it might be a different matter, but I don't know.
