Apple has engaged two camera lens makers as suppliers for the next-generation iPhone, according to reports.

Taiwan Economic News claims that Largan Precision and Genius Electronic Optical will supply lenses for the iPhone 5, which will have an 8-megapixel camera.

Rumours that the iPhone 5 would have an 8MP camera have been circulating for some time, with Sony seemingly giving the game away as far back as April.

Both Largan Precision and Genius Electronic Optical supplied lenses for the iPhone 4, which has a 5MP camera, the report notes.

Earlier this week, it was reported that assembly of the iPhone 5 had already begun at Foxconn and Pegatron plants. Last week it was claimed that the iPhone 5 would revert to a metal back, the iPhone 4 having a back panel made from glass.

Evidence that the iPhone 5 launch will take place in early October has gathered strength in recent days, though German network carrier Deutsche Telekom is already taking pre-orders for the device.
