I have 3 Rayqual Nikon AI to Canon EF lens adaptor rings for sale. These convert a Nikon F mount lens to fit a Canon EF mount body (ie Canon EOS range). Have worked very well for me but selling them as I am now using Nikon bodies.
These are great quality, high end adaptors and are manufactured to be the exact thickness to maintain calibration of infinity focus on the lens. Each has a custom mounted AF confirm chip as I was using them with the Zeiss ZF range. These enable the AF confirm light, EXIF lens data (focal length & max aperture) and increase exposure accuracy.
1x Rayqual Nikon AI to Canon EF lens adaptor with lens cap + AF confirm chip with exif data 25mm f2.8
1x Rayqual Nikon AI to Canon EF lens adaptor with lens cap + AF confirm chip with exif data 35mm f2.0
1x Rayqual Nikon AI to Canon EF lens adaptor with lens cap + AF confirm chip with exif data 50mm f1.4
The AF chips are bonded on with epoxy and I can remove them if they are not wanted, or a bonus if they are of use to someone!
They are in very good condition with no obvious signs of wear. Originally bought from Robert White (http://www.robertwhite.co.uk/product.asp?P_ID=2062
) for £115+vat each plus costs of sourcing and mounting the AF chips.
Asking for £(GBP)75 each (includes UK postage and Paypal fees). Other shipping at cost. I have 100% ebay feedback - PM me for details.
