As those with a really good memory may recalled from an early thread, I had some problems with my Mk II ttl converter. It went back to Sea and Sea and they have finally sent me a brand spanking new Mk III model. The only thing is that I have since changed my wiring back to non-ttl [the DX70 housings needed a wire change for ttl] and have no inclination to change it back again.
The upshot is that I have a brand new Nikon type Mk III converter that is surplus to requirement. Unused and still in its box. I would assume [but don't hold me to it] that it still has a fully guarantee.
I am in London/Surrey in the UK but happy to ship out pretty much anywhere [although if you are in the far east or africa and have made very few posts I reserve the right to sell it elsewhere].
I am open to offer. The units go for £339 in the UK.
