I know, I know.
I enjoy taking photos with my 808 smart phone camera, e.g., like the photo shown in another thread recently:
The photo as shown above has a FoV equivalent(35mm) to 200mm. So, it is close already to 300mm, although not when cropped to APS-C (equivalent(35mm) to 500mm).
But nevertheless, it clearly is a tele photo, taken with a phone, when most people (e.g. on a beach) would not not (yet) suspect you to do so.
Below, I attach a second sample, same FoV (equivalent(35mm) to 200mm, now actually on a beach too
The image quality isn't quite on par with a dSLR, but note that this actually is a 100% crop from 41MP taken off a mobile phone... Moreover, I didn't make sure the shutter speed was fast enough, as the phone, obviously, wouldn't select a very fast shutter speed for what it thinks is a 24mm wide angle shot...
