Forum has suggested that a Kenko Teleplus Pro 300 N-AF 1.4X would be a reasonable converter for a AF-S Nikkor 55-300 1:4.5-5.6 GED. What would be the better choice between the Kenko and a Nikon AF-S TC-14E 11.also 1.4X. Costwise I cannot go wild so it must be either one of these or something compatible to my lens within the same price range. Any advice for this Phototechnologically disadvantaged member will be appreciated.
