Just a heads up for someone who might experience this issue. My newly arrived FT-1 would not work on my V1. I read the directions and it said that you need Firmware A/B 1.10. My camera had 1.00.
Upgrading was not easy and I could not do it on a Mac running OS 10.8 at all. I could not copy the bin file to the In camera formated SD card-I tried from the internal SD card reader on my MacBook Pro as well as an external card reader.
I booted up my Sony Viao with Windows 7 and again I could not get the bin file to transfer to the SD card reader on the laptop but I was able to open the downloaded file and drop and drag the bin file on the SD card that was on an external card reader.
FT-1 works great and the focus is killer.
Hope this helps someone else.
This was the hardest firmware update I have done yet with Nikon.
