had these 2 superb lens, but feel 50 is better.
At the same distance , 2-3 feet from a model. Both lens shooting at 2.8, 50 seems to be sharp all the time. 85 on the other hand is abit erratic. Sometimes sharp, sometimes blur. Stopping the 85mm down to F4 is much better or same as the 50mm at 2.8, same distance.
Any idea why is this so?
