I find myself in this situation a lot. Girls' night out in a nice, dimly lit restaurant. I usually bring my canon EOS-20D with a 50mm f/1.4 for the food shots (I'm a noob so I don't have an off-camera flash yet). When the time comes to do obligatory group shots, I usually just dial it to program and use the flash light. The reason is I can't possibly get a good shot without the flash with a prime lens. If I dial the aperture up, and stand far enough to accommodate a full table of people, then only one person would be in focus. I also have a 17-85mm f4.0-5.6 lens, but I haven't used it much. Am I pretty much screwed in this situation until I get an off-camera flash? And say if I get a flash, what kind of lens is better for this scenario?
