I have been using RF2870 since it’s launch, I can say it is superb even wide open.To be honest, the only comparisons I’ve seen between fast RF primes and the 28-70 have been people shooting test charts. This is not a substitute for real world evaluation. In charts, the 28-70 does not compare well in terms of sharpness.
