Although the camera's specs are the same, from the viddys that were posted to Milton's lens change thread (which he has since made private) .... it looks like the Plus has a much better chance of easily being assembled at the factory with the lens square to the sensor, than the P2V does with it's various alignment screws and etc.
This shows up in the number of P2Vs viddys that have significantly softer corners than most (if not all) of the Pluses.
As indicated in my thread regarding the contrast, color/tint and focus changes of the Plus, I think it's ability to point straight down exasperates the "opposition effect" (that was pointed out me as being something all cameras have to deal with) and ..... just like when you get a better sound system that amplifies all the junk you never heard on your "pitiful, portable, picnic player" ... the rock solid steadiness of the Plus' gimbal might not let the image's light and focus distortions, camera vibrations and other artifacts go as unnoticed as they do on the P2V as it bumps and bounces all over creation.
I'm looking forward to using the camera setting suggestions that others recommended, as soon as it stops raining here.
I also noticed that we now have a setting for "anti-Flicker" that we didn't have before, but lost the medium FOV setting with the newest app.
Also, we can now cut-n-paste off the SD card while in a PC, were before we could only do copies .... and needed to delete anything off the card via the app.
