I went and googled this and I looked at my notes from visual arts and photo class. The person above me is right please tell us what a non dedicated manual flash. You can have three speedlites if you can afford them as per my T4i manual and if could I would for portraits in the middle of the night or something plus the sync capability and then the remote and then I would like the GPS module. I apologize for the digression I will try and definitely help you just please clarify what you mean. Thank you so very much.
