Bought my lightly used A7RIV here on FM B&S just about 5 years ago. It was an upgrade to my A7RIII and the AF was much improved over the A7RIII. Use it for mostly indoor/outdoor portraits and found the Tracking feature to be worthless even with Batis and Sony GM lenses. However the Eye detect AF feature is excellent and that is how I shoot to this day, very happy with the results.
Also tried the Tracking feature with my 100-400 GM for airplane photos and most times it was OK on bright sunny days. But with clouds, it backfocused a lot, so I quit using it for these types of photos as well.
