I bought this lens because I (and most people don't) want a 500-600-800F4 lens for about 8- 10,000 to start. It's a fraction of the price and yes it's only F5.6 but you get a darn good lens, I paired mine with a D850 and wow just wow. I love this lens and have also paired it with a Nikon 1.4 Tele and noticed a loss of around 3-4% in image quality. So that's a win. If you are considering buying this lens, DO NOT buy it, you will not regret it.
