Ozdemir Zia, 76, was turning onto Vincent Road when he hit Edna McLean at 10.31am on September 11, 2021.
On Monday (January 27) Zia, of Kidbrooke, was found guilty of causing her death by careless driving after an Old Bailey jury deliberated for five hours and 38 minutes.
CCTV footage was shown in court showing the collision with the elderly pedestrian and members of the public rushing over to help as she lay on the road.
The court had heard how another pedestrian heard the noise of the bus hitting Mrs McLean and looked round to see her body travelling through the air.
Mrs McLean suffered brain injuries and was airlifted to hospital but never regained consciousness and died two days later.
When he was spoken to by police at the scene, Zia said he had not seen Mrs McLean until immediately before the collision and then applied the brakes.
He added that people do not always look before crossing the road, prosecutor Nadeem Holland had said.
Traffic collision experts concluded the driver began turning into Vincent Road while his view was obscured by another bus, Mr Holland said.
A pillar inside the bus also created a “blind spot” but the driver could have moved his head and upper body to look around it, he told jurors.
Mr Holland had said the CCTV footage demonstrated the defendant’s driving “fell below the standard expected of a reasonable, careful and competent driver”.
He told jurors: “The defendant did not take sufficient steps to cater for the possibility of pedestrians crossing Vincent Road as he turned into the road.”
He said that although the defendant was not speeding, he should have travelled slower to give him more time for the manoeuvre.
The defendant should have also moved to mitigate the blind spot created by the pillar in the bus and waited for the second bus to clear his field of vision before turning into Vincent Road, the prosecutor said.
The defendant, who denied the charge against him, will be sentenced by Judge Nigel Lickley on March 14.
