Kenko 1.4X PRO 300 TeleconverterDG-Canon EOS Review

This Kenko Teleplus PRO 300 DG AF 1.4x Teleconverter works well with my Canon EOS 40D with Auto Focus/Manual Focus of the following lenses: Canon EF 70-300mm f4.0-5.6 IS USM, EF 70-200mm f2.8 IS USM, Canon EF 28-135mm f3.5-5.6 IS USM, and Tamron 28-75mm f2.8. It is well-built and it is on par with Canon 1.4 extender in performance. Given with enough light source, you can get better and sharper images for Canon EF 70-300mm f4.0-5.6 and 28-135mm f3.5-5.6 (at f/11-f/16) and EF 70-200mm f2.8 IS USM and Tamron 28-75mm f2.8 (at f5.6-f/8). I have not tried this TC with lenses above 300mm focal length.


On the other, the problem that I have using this Kenko Teleplus PRO 300 DG AF 1.4x Teleconverter is that the camera cannot register automatically in the EXIF data the correct focal length and aperture setting of the aforementioned lenses. However, it is understood that using such TC 1.4x like this a one f/stop loss and 1.4x increase in focal length of the lens being used are expected. But on the other after manually adjusting the aperture setting which is required to get sharper images, the camera can identify now and register the adjusted aperture setting as reflected in the later EXIF data. This is only a minor problem which has nothing to do with image quality of our taken pictures and which can be ignored.


As of the moment, I am happy with this Kenko Teleplus PRO 300 DG AF 1.4x Teleconverter which is giving me an added range for my lenses without suffering the loss of image quality of my pictures.


I highly recommend this TC for your added range.
