DXO-One ergonomics

[jpb]

Interesting concept which reminds me of the Nikpn Coolpix 995

On the DXO One you hold the 'camera'  by the lens housing then orient

the 'swiveling' screen toward your eye (like on all D cameras),

whereas on the Nikon you firmly hold the camera by the screen

(never loosing eye nor hand contact with the machine),

then orient the lens housing. toward the subject;

Which method is best for you?

One question remains, how sturdy is the USB link between the lens housing and the iPhone?
