I can confirm that the RP+85mm is great for moving 3 year olds The trick is to avoid high contrast, that lens has horrible CA. Let's see if I can find some matte black hairclipsI think that depends on what you're photographing and what look you're going for creatively. Eye-detect AF has been an absolute game-changer for me and I bought an RP in large part because of it.
If I'm trying to photograph my 3-year old playing, running and darting with an 85mm F1.8 wide open and him filling the frame, it's nearly impossible to get more than a 20% hit rate without eye AF. The DoF at that distance is tiny. No other AF method could produce the consistency I get with eye AF in servo mode at that aperture. Sure you could change aperture, distance, or focal length for more DoF, but I don't have to compromise my vision for the photo with eye AF. I get amazing background blur and tack sharp eyes pretty much every photo.
I wouldn't buy a camera going forward without it. I'd be surprised if the new 1D didn't have it in some capacity.
