The Nikon F, Canon EF and Leica R Baveyes 0.7x adapters are now in Stock and shipping for the first time on [shoplink 24353 ebay]eBay (Click here to check price and details)[/shoplink]. These Baveyes work just like the Speed Booster but do cost much less. Of course we will have to see if they are almost as good as the Metabones. Let me know if you find some test and samples. Thanks!
