This is the price I have been quoted direct from Kindai.

Leica R-EOS adapter Yen 15,300 (~S$233)
C/Y-EOS adapter Yen 15,300
M42-EOS Yen 7,650 (~S$110)

For those who have used it. Are Kindai adapters better than Tagotech, and in what ways? I have no problem with Tagotech. I am aware there is still the more expensive Novoflex. Again are the Kindai inferior to Novoflex in any way?
