Despite his decent margin, it was apparent Crutchlow didn't have the front running pace, allowing Camier to catch relatively quickly and simply slip up the inside at Priory on the first time of asking on lap nine.
Crutchlow tried to give chase, but Camier would not be challenged again as he crossed the line for his third victory of the season by a just over a second. The win adds to his triumphs at Snetterton and Croft.
More importantly was the rider in third as Byrne came over the line 'wheelie and all' to celebrate a second British Superbike Championship, five years after his last title win. It also marks a fourth victory for the GSE Racing team and their first since 2005.
Rutter came home a very distant fourth after struggling to maintain the pace of his front row qualifying position, while Simon Andrews was a fine fifth after benefiting from the retirements to climb from 13th on the grid.
Smart had held that strong fifth for nearly the whole race when he came down at Priory, while the beneficiary from that problem, Harris, who had battled his way up the order valiantly, was also forced to retire close to the finish with a mechanical problem.
It meant Mason scored the best result for a Cup rider this season in sixth place, a marvellous performance for the Quay Garage Honda rider, not least because he held off fellow Honda riders Tristan Palmer and Jason O'Halloran in the process.
Stuart Easton saved some face for Kawasaki in ninth, while Atsushi Watanabe sneaked into the top ten.
Haslam, meanwhile, did his best to recover from his earlier fall to finish in a fine 12th, just ahead of Sykes in 13th. However, Sykes was later disqualified for the collision, while he has also been moved back three rows for the second race too [see separate story].
His loss from the results sheet means David Johnson finishes 13th, Chris Burns 14th and Peter Hickman 15th, the Red Viper Honda scoring for just the second time this season.
