I have a zenmuse xt640, 13mm focal length, 30hz, non radiometric for sale. camera is used but in great condition. I also have the adapter for the M200/210 series if needed. I have used this payload with the I1 as well as a 210 and had great success, but have decided to move up to the XT2 for the 25mm option. Pictures available by request.
If you have not already purchased your XT2, we keep the 25mm in stock and would take in your other on trade....and we are just south on I75 if you want to come down and check out the XT2 in person. Feel free to reach out to us offline or PM through the forum - we love to help make things like this work out for everyone.
