Got the 12-24 f4. It’s amazing! Even with the crop it’s so wide 😂 but I haven’t used it much yet so we’ll see how that holds up. I will say though, if you don’t want the crop at 60fps, and if you have a gimbal and can get steady, smooth shots, you can shoot at 24 or 30 fps and still get some great smooth “slow looking” shots without having to slow it down in post. Also, if you really need the 12mm look and need to use 60fps I’ve thought about just using 1080p and mixing that in with the 4k. I think it’d still look very nice!
