(DSLR Sony Alpha) want the royalty 5:01 macro lens but I can not work on my camera without an adapter, I wonder if there is a fee to mount the adapter sony
The overall objective lens adapter is to allow photographers to adjust the lenses legacy to modern horses. Since the EF system is relatively new, more or less digital, and very vivo, there is much sense in her lens fitting. Also, since the election of Canon design, only mounting a modern (M4 / 3) is to be able to achieve approach infinity with a Canon EF lens (and as an adapter exists because of this.) Apart from EF for m4 / 3, I do not think I've ever seen an EF adapter available XXX. The Canon Nikon adapter you mention is probably a Canon FD to Nikon mount. The assembly of FD is the predecessor of current Canon EF mount. It is not only a theoretical solution that comes to mind, namely: Buy two sets of extension tubes cheap third party from the same manufacturer ** **- one for the Sony Alpha mount and one for the EF mount. These tube sets usually sell for $ 10 each on eBay. Be sure to ask the seller (s) marks what is printed on the product box and the outer diameter of the tubes to ensure they are universal. When they arrive, simply mix and match the pieces so that the tip of the lens is Canon and the end of the body is Sony. You definitely lose infinity focus (but do not need to macro anyway) and the fraction of one or more stops of light as a result. However, as a bonus, the rate of increase is probably greater than 5:1. If you would like to know more about this possible solution, let me know so that I can offer you a more detailed explanation.
