I have an opportunity to photograph a restaurant, chefs and food during a fast paced service. Need help with lens choice, I have a canon 7d considering buying a EF 100mm F 2.8 USM or should I use my EF 50mm F1.8? Also need a speedlite and are wondering if the Orbis light ring could be beneficial. Not able to use tripod or addt'l lightening as the restaurant will be busy and crazy. The kitchen fairly well lit but the restaurant is trendy Italian inspired, it's dark with candles, light fixtures with flames, brick pizza ovens, lots of exotic wood paneling, rustic decor, and a slate floor. Any help would be most appreciated, Thanks Ev~
Also have the EF 70-200mm F2.8 L
