Putting aside the earlier probable source photos, I was wondering about it from the other side. If those specs were accurate, how big would the optical system have to be?
Firstly "1 inch sensor 12,2×8,8mm" doesn't match with anything I can find here
. Let's round it to 4x crop factor for that sensor. 35mm equivalent would therefore be a tad under 9mm focal length. How short can you make a 9mm focal length lens? As that, combined with the sensor thickness, and then the screen thickness assuming they're overlapping as shown, would determine the phone thickness. This is going to be a bit of a brick even if they made it telephoto type, unless it pokes out when in use?
Repeating for the 2nd claimed sensor, 1/1.7" at 4.55 crop factor. 3x zoom lens, from what angle though? Usually 24 or 28mm equivalent, let's say 24mm equiv. in this case to make the tele end easier. We're still looking at 16mm max focal length required here.
As a side note, I have been wondering if I'm the only person that'll rather have a slightly thicker phone if it means I get more battery life out of it? Add an extra mm or two wont make a practical difference to carrying, but if that extra volume was given to putting in more battery, I think we could double life!
