I have had to upgrade my 1.4x converter to match my new 500mm, and therefor have a mint example of the mk2 version for sale, complete with its box, instruction sheet,case and instruction sheet.With most lenses no difference in quality would be noticed between the mk2 and new mk3 versions.
Also have the 2x converter for sale as above in mint condition.With the NEW mk2 300,400,500 and 600 lenses the new mk3 converter is a better bet, but at a price!
If anyone is considering a Canon converter please let me know after the 23rd of this month.Each of the converters will be priced at £190, below that of converters on ebay which are not mint. A Lenscoat cover will be thrown in too.
I will be available tonight if anyone wants either or both. 01938 553257
