ADVICE on CONVERTERS for 40D and 400mm lens
I need some advice folks. I have a Canon 40D and 400mm prime lens. Its my birthday in a few weeks time and the kids want to spend some money on the old man. Now I need a converter.
Any thoughts on whether it should be a 1.4x or a 2.0x. also will I lose the auto focus and do you lose much of the picture quality. One last question where do I get the best price. Any help would be appreciated.
Jim.
Hi Jim.
I use the Kenko pro 1.4x.I bought it from an ebay shop called UR Galaxy based in Hong Kong.It only took 6 days to arrive and cost me about £65 incl delivery.If you were to get a 2x you will notice a big difference in image quality so I would opt for the 1.4x.You should retain AF with your kit by taping the contact pins on the converter.
Good luck,Mike.

Hi Jim
I also have the Kenko pro 1.4x and use it with the Canon 40D and 300mm f4 prime lens. I do not lose autofocus at all, but apparently you do if you use a 2x converter. There is hardly any difference in quality between this converter and the Canon 1.4x.
