Hi everyone, I know you have had these questions before from those of us who are new. So here we go again. I was asked to shoot a small family reunion (30ish people) at a local club. I would be filling in on short notice. The request is to take some group photo's, candids (smiling faces) etc. The reunion will last about an hr (at least the time in which they would like photo's is an hr). The normal photographer uses 80-200 lens and either a Nikon d70 or d3 (I think). I have a 30d and 5d (newer to me). I was thinking of using my 85 1.8 on my 5d, 70-200L on my 30d, periodically switching to the 17-40. I don't think my 50 1.8 will serve me well. I worry about the 17-40 and 70-200 because they are f4. I was told that there should be plenty of natural light (and some fluorescents, oh fun). But we are shooting between the hours of 7-8pm.
Any suggestions as to best assign my lenses, would be greatly appreciated and if I should assemble group shots in the beginning or at the end of the engagement. Actually any suggestions would be great.
