Compatability Question.

[Margaret Holland]

Hi,
I am considering the purchase of Canon EF100MM F/2.8L Macro ISUSM but would like to know if it will accept my Sigma Electronic Flash Marcro EM/140DG EO-ETTL 2 which I use on m Sigma 150mm lens.
All this fits on my Canon 50D

Can anyone please advise.

Thank you,

Margaret

Looks to me like you would need to get a 67mm adapter from Sigma and all would be fine. - TF
