Telephoto Zoom Lens

Telephoto Zoom Lens
Why they say double the capture of a digital tele?

For example, say a 150 mm zoom on a Digital Slr is equal to 300 mm, non-Slr Digital zoom. How is that possible, I searched through both digital and is not the same, the images on TV not digital slr seems much closer. Are they trying to fool?

This formula only works with Olympus SLR. It's about the size of the sensor of a DSLR digital when compared with a full frame 35mm frame, 36 x 24 mm. Nikon APS-C sensor, a 1.5x factor like Pentax and Sony. Canon are 1.3 x 1.6 x again depending the size of the sensor.
