Hey got a a99 lemon 2 days back. Just to share my experience so can add to ur checklist
Do bring own cam and own lens down. The unit itself is ok. Can af. However something din feel rite. There was a slight lag before unit focused using shop's sam lens. Tested at hm and found that there is a slight lag when I centre spot af before lens lock on. Updated firmware and mirrored my another a99 af setting. There was a slight pause before lens shifted.
Fyref la.
