I have a Nikon AF-S Fisheye Nikkor 8-15mm F/3.5-4.5E ED in like new condition along with both a Nauticam Nikon AF-S fisheye 8-15mm F/3.5-4.5E ED lens zoom gear (SKU # 19150, which lists for $195.00 USD) and a modified Nauticam focus gear (originally made for Canon’s 100mm f/2.8L macro lens) for when the lens is paired with a Kenko 1.4x Teleplus Pro 300 teleconverter. I am also including Kenko 1.4x Teleplus Pro 300 teleconverter that I had used with lens inside my NA-D500 housing.
When I was using a D500, this lens with the 1.4x teleconverter proved to be far better alternative optically than what I saw with the Tokina 10-17 fisheye. The funny thing now, since moving to a Nikon D850 and my newly modified Nikonos 13 R-UW lens, I now longer have a need for this set up. Sure the 8-15 works fine with full frame, as long as you are happy with 8mm circular fisheye and 15mm full frame fisheye. The thing is, I don’t care about shooting circular fisheye images, as they are more a novelty than something of true practical use.
My selling price for this entire kit is $1100.00 plus shipping.
