Have you looked at Logitech K800?
Sony/Panasonic was in reference to TV
I have a couple of their Neutral Density filters.
As a suggestion update to the FTZ II it's same price as FTZ and doesn't have bottom as FTZ has.
I have purchased several lenses on Amazon with no problems and are not gray market.
Just a note in reference to statement on third party batteries with own charger - Kastor has it's own charger and their batteries of the one's I use are compatible with Nikon charger.
I have used Wasabi & Kastar without any problems.
Still have a film camera and use occasionally.
All my DSLR cameras when I put card in and import into LR room no problem but when importing from Z camera in LR I get: Preview unavailable for this file. So, I must take an extra step by using Adobe DNG Converter saving to folder and then importing from that folder.
I have Lightroom 6 but what I found out is if you buy a Z camera it will not allow you to import photos until they are converted(I use Adobe DNG Converter).
