Aluminum camera cage for Sony FX3, TILTA TA-T13. - Model: TA-T13 - Compatible models: Sony FX3 Thank you for viewing. I am selling my FX3, so I am putting this up for sale. It seems this type is no longer sold, but it was very easy to use. It shows its age in places, but I think it is still usable. The items shown in the photos are included. I lost the magnetic key for turning the screws right after I bought it. I have been using a screwdriver to attach and detach it instead. Thank you.
