Before the Canon PowerShot SX60 HS hit the market last fall, there had been rumblings that it would have a 100x zoom, but it *only* came with 65x zoom which worked out to a focal length of 24-1365mm. There was a patent for a 100x zoom optical formula
at that time, but I guess it wasn’t ready for market. Now, another 100x zoom patent has come to light, this time with a 24-2400mm focal length when factoring in the 1/2.3″ sensor.

Could the PowerShot SX70 HS get a 100x zoom? Nikon has brought us the 83x zoom Coolpix P900, so it only makes sense that Canon will try to outdo the P900 when the next iteration of the popular megazoom PowerShot gets unveiled, which isn’t going to be for a while yet.
