Anyone use this lens for airshows? I was thinking of picking up a used one for an airshow in a couple of weeks but feel like I might be limited. I've shot a very similar airshow before with an A7rV and a 50-300 and that felt like I didn't have enough reach and had to do some major cropping on some of my favorite images, but then others were perfect. I'll also have a Panasonic 100-300 with me that I could alternate, but I'd have to be changing lenses.
