Thanks and BTW how do you like the 400mm 5.6? I am in the process of getting one
It's a fantastic lens. Although once you start using it, you'll want longer lol. It's typically a sunny day lens unless you can ramp up the ISO and be happy about it. Can't go below 1/400th or it's serious camera shake if you're skinny like me. I just lean it on a fence. One person told me that I needed a bean bag with it, and it's not till now that I know why. Otherwise there's not a lot better for IQ and speed.
