Hi, I use Nikons for weddings and have found the flash to be very accurate with the Fuji 400 film. I usually set the flash for +.3 and get very good results. The lab tells me my negatives are well exposed. As to the 70-200, use it on a tripod from the balcony for ceremony portraits. For this I generally use Fuji NHGII with the camera set for +.5 exposure compensation in the program mode. For bride and groom and small groups I use the 85mm 1.8 and a Photogenic Powerlight 375 in a 24x36 soft box and work at f5.6 determined by my flash meter set at 400 and a shutter speed of 1/15 to 1/60 depending on the light level in the church. I generally have at least two cameras working with various lens combinations. Good Luck
