Hi!
Im going to be doing some close up images of people and was considering the Sigma EM-140/EM140 DG Ring Flash...ive done a search on the forum and cant find too much info on using these for portraits etc. Would this unit be powerful enough?, i found a few posts mentioning for proffessional glamour they use mega super rings....if anybody could clarify i would be most greatful!
Many Thanks
