However, they will only be delivered in a cheap cardboard box. When VT30 very nice, well-made plastic boxes were there that were visually appealing and the glasses are perfectly protected.
Negative should also be noted that the glasses are once again equipped with coin-cell battery instead. Panasonic TC-P55VT50
This is in my opinion a serious step backwards!
VT20: button cell
VT30: battery and carrying case
VT50: button cell, no box
Addendum to crosstalk in 3D:
I landed on the VT20 VT30 VT50 now on. The VT20 was the first 3D TV from Panasonic and had very low compared to their competition, but visible ghosting. The VT30 was a bit better, but still not perfect. VT50 when I noticed the ghosting is now back stronger. Sammy in particular generated by the 3D Bluray strong contrasts with corresponding ghosting. I do not feel as strong as the VT20, but more than the VT30.
In 3D Bluray Grand Canyon, I noticed that there is an active change of ghosting that I have noticed when VT30 never. These stocks will probably act to the new "ghosting prevention circuit", which was first introduced in the 50 series.
It occurs on the unsightly effect of ghosting (crosstalk) is visible at the front and then suddenly vanishes there, but at the same time looming in the background, where it was not before.
This circuit should be improved.
