You are right, I use the 85MM f1.8. That's a lens with a reasonable rate. I tested ist big brither 85 f/1.2, the results that I obtained are a little bit better but not proportional to the price difference. For horse riding pictures, I use also 50mm f/1.4 and 200mm f/2.8. My next lens will be 135 f/2 but not yet
