Kenko teleplus Pro 300 DGX 1.4 AF Teleconverter - Canon Fit
Kenko 1.4 Teleconverter for Canon - I'd like to see it find a home as I no longer use it.
I am selling it because I have sold my 100-400 mark I lens. The Kenko is the only teleconverter that can be used safely with this lens (the Canon TC's clash with the rear element).
It is also very useful for macro photography. Allows Auto Focus and normal function with Canon bodies and supplies very good image quality.
I have used it with canon 100-400, TS-E 24, 45, 90, 100mm F2.8 Macro, 400 F5.6, 300 F2.8, 500 F4 and Sigma 300-800.
