Visible crew/equipment: When the guy on the roof stands and takes aim at the window in preparation for Brian, the film crew are reflected in a window behind him. (00:13:00)
Visible crew/equipment: When Brian at the end says "don't make me laugh", if you look at the chrome bumper of the green Torino he's leaning on, you can see a member of the crew moving. It's not Toretto as he's on the other side of Brian, and it's not any of the Police as evidenced by the following shot that still shows them to be far away.
Visible crew/equipment: When Brian steals the Humvee, and stops for Dom to get it, there is a camera very prominently reflected in it. (01:01:50)
Visible crew/equipment: After Brian transfers Mia in the FBI building, there is a shot of a red car with chrome bumpers. In the bumper you can see a cameraman walking forwards with the camera. (00:24:15)
Visible crew/equipment: Just after Dom says "T, you're up," a camera moves across Han's truck and up to the window. When it moves the shadow of the camera can be seen on the orange paint, moving. (00:03:00)
Visible crew/equipment: When Han does the handbrake turn right at the start, you can see the camera car reflected in the chrome bumper in the closeup. Slo-mo helps but is not required. There are also skid marks from previous takes. (00:02:00)
Chosen answer: It's a slightly tricky one to answer because the movie doesn't give very many clues. What we do know for a fact is the events at the start during and up to the conclusion of the Petroleum tanker heists was set before Tokyo Drift as evidenced by Dom speaking to Han with a view to returning back to Tokyo. After that it gets a little fuzzy. Some people claim the entire movie is before Tokyo Drift, but that simply cannot be the case as there are lots of 2008/2009 model cars around the movie, so the general consensus is the very start is before Tokyo Drift, and the time when Dom comes out of travelling/hiding and gets the phone call that Letty is dead is now after Tokyo Drift.

This is not right. The entire movie takes place before "Tokyo Drift", as that is where Han dies. He is still around for the next two films and then dies in the seventh where events catch up with "Tokyo Drift" and then continues where it left off.
Yeah, Han's not dead either, he's back in the 9th movie.
