Those of you that may have been following my development of this adapter should know that Mike now has a good stock of them. There on his web site for order. Great news is that as well as the F3 it works really well with the Canon C300 and APS-C DSLR’s. If you buy the F3 kit you can remove the rear part and then the adapter will work on the C300 or 7D etc making it really versatile.
