Teleconverter for Nikon 85mm 1.4G
The only converters that would have a chance of working are the Kenkos but only the 1.4X Kenko (yielding a 120 f/2 lens) is considered sharp. The latest Nikon 2X TC receives rave reviews but as mentioned, it won't fit the 85/1.4G and it costs about as much as a used EX+ 180/2.8 AF-D from http://www.keh.com . If saving money is a concern, I'd head right over to KEH and pick one up. Based on the images I've seen from that lens, I doubt you'd come close slapping a 2X converter on the 85/1.4G if a good one was even available.
