Bought a month ago. Works great with the exception of fast action and sports on my 70200 f2.8 GM OSS lens. Don't let that stop you though! Does well aside from that.

Pretty good

On a 7RIII with 200-600 lens it works sort of OK, best in really good light. On a 7RV with the 2-600 and ok light, works good.
