Yeah. I don't think they require studio quality, and for the glasses I have are just f/4 for my 17 to 40 and my 70-200. I do have my nifty fifty 1.8...it'll get the job done..was plaaning to get the 1.4 but got the 70-200 instead..since the sun doesn't set till 8..and I think the event starts in the evening so lighting should be okay..ill probably scout the garden this weekend. And yes, I'm sure Sean can give me some advices on portraits shots..I'm such a newbie in this area...
