I was thinking last week the rear camera view on mine was looking different (
thought I was seeing things!)
Thanks to all for confirming the "moving cameras"
Is it a quick fix to put it back to how it was?
I do think mine was wrong to start with but now after it has moved it is in the correct position as it shows part of the bumper like the photo in the manual
I'd be surprised if the physical camera was really moving, maybe there is some auto calibration of the camera image position to align the tram lines, but not sure how it would do this given the image has no real reference points (other than the bumper). I'm guessing this doesn't move after a trip to the dealers where they might have physically re-aligned it or updated software? So must be some form of auto-calibration?
The cameras do seem quite clever how the same one can give different views which I presume is done via the software as oppose to a mechanical zoom lens or maybe they have an electro mechanical iris? so maybe they do auto calibrate, I wondered if mine wasn't seated properly when fitted but after several shuts of the boot it is now in the correct position as it has moved down slightly prob only a mm or so - I don't slam the boot as it has the electric open/close and it has not been back to the dealer for anything

The reversing camera actually moves when you change views. Get someone to alter the view while you watch the camera. The movement is internal, that is, the iris moves behind the lens.

Ahh right so then there is a possibility it could get stuck in the wrong position, will watch it move next time Im out
Thanks for that info

I'm not sure it could get stuck, if you mean mechanically (as it appears to be a sealed unit). However, it is possible to look at the bumper and equally avoid looking at it when viewing the rear camera in normal 'Camera' mode (rather than when in actual reverse gear, when it is not user-adjustable), so electronically the iris can obviously adopt both positions. Mine changed a few days after purchase (like many have described here) so that I can now see the bumper when I couldn't before. The only thing that happened between these two events was that I viewed the rear camera in 'Camera' mode and experimented with tilting, panning, and zooming it, and my guess is that it then defaulted to the different position (whether that was a correction or a fault, I don't know).
As a tool to aid reversing, it works just as well with the new view in terms of alignment, is better in terms of close manoeuvring, but worse in terms of spotting something at distance behind the vehicle. The ideal solution would be to offer the same tilt/pan options which you get in 'Camera' mode when in reverse gear. (Suggestion for LR??)
The problem with allowing PTZ (Software Pan/Tilt/Zoom) in reverse is the tram lines would have to be "clever" and be able to move with whatever viewing position you choose, this will be why it's fixed in reverse gear mode to ensure the tram lines are correct as they are just an overlay on the image from the camera (maybe if you could disable the tram lines and then allow PTZ quickly). I would think LR also thought it better to always see the same view in reverse so you get used to the distance etc otherwise you might get caught out by the different view.

That makes sense! Maybe I'll have to use the rear camera to have a look where I'm going
before I select reverse gear!
On refection, I agree with your point about a standardised rear view, but (as I mentioned above) mine did, in fact, change in use. Have you any thoughts as to why it might default to a different position after using the 'PTZ' facility (does this seen technically possible?), and which view you think is 'correct'?
I did a few weeks ago play around with the cameras zooming in and out etc, so maybe like yours it was due to me playing around with it and I just haven't noticed till now.
Could it be that from the factory the camera is in its instal position and then when you zoom in and make use of the iris it then goes back to the new correct position showing the bumper? maybe they should be initialised before they left the factory?
Im happy now as I think it is in the correct position as it is better to see a bit of the bumper as it helps judge the distance when really close
