Back-in-time buffer is amazing, I have it on a Casio camera of mine. You hold the shutter halfway and it takes photos at whatever speed you choose (I usually have it at about 10fps), then when you press fully, it stores up to 40 shots from before you fully pressed the shutter (you choose beforehand how many shots to store from before the full shutter press). I would love to have a full-frame mirrorless with that feature, but alas. I've got a lot of nice photos of birds taking off, fish jumping out of the water, street photography to capture people in an exact position of my choosing, the exact moment a bat hits a ball, and many other things that would have been almost impossible to capture otherwise. It amazes me how stuck in the past camera companies must be, there's so little innovation. Even something as basic as wifi/phone support is almost always half-baked and barely functional. There's so many opportunities to improve with good phone integration too. You buy a $2k SLR, yet it's still difficult and time consuming to simply snap a picture and send it using your phone. It shouldn't be this complicated.
