It's rare that f2.8 gives one too much depth of field. However, I do have an FA 50/1.4 if I need it. And unlike some of the older primes, the new zooms are actually sharp at 2.8. The DA* 16-50/2.8 is sharper at 50mm and 2.8 than is the FA 50/1.4. In terms of low light, high ISO performance makes 2.8 feasible almost anywhere. Paul
