Have the LVR in the set with the HDR-AZ1 and could get the LVR2 the VorgÃ'nger, compare the LVR1. Although they appear identical, the new version LVR2 a substantially lighter (approx 2.5x) and blickwinkelstabileres display, making it even outddortauglich GPS is also better than when it is incorporated as in the HDR AS100. See my photo to compare (the remote to the "GPS" lettering is the LVR2) Further improvement is noticed: The bracelet is now lÃ'nger, making it more comfortable on and off.
