For close ups (macros), you will be pretty close to make this combination work....but given that you are trying to do macro work, you have a fighting chance.... For R lenses, a different story.... Yes, you can use certain flange swaps ( remove the Leica R flange and replace with a Nikon Flange) that offer focus confirmation. Look on EBay for sources.... Or Leitax may have something.... Leica R lenses have a LONGER focal plane register than Nikon ( I think the difference is 0.5mm).....You CAN change the lens flange and get to infinity..... The Sony Alpha cameras ( like in A7) have an even shorter focal plane register than the M lenses... which is why you can use M lenses on a A7 body and get to infinity.... You may want to try your Sony body to get through the lens focusing with M lenses..... ( I think you have a A7r.....?) Frank Filippone Red735i at verizon.net When using Leica lenses (manual focus) on a Nikon D 810, is there a way, even a hack, to get audible focus confirmation, a beep, along with the green light, when focus is achieved ? many thanks, steve
