Kenko MC7 is what I have. It's readily available used, and quality is
very good. However, you lose auto focus on this slower zoom, and aperture
reported is not correct. However, it does give me 600mm at less than 50
bucks. Exposure is still fine, and manual focusing is not so difficult.
See my webpage for some samples, and email me privately if you want more
info.
