I used my 1dmkIV, a tamron 2x, and a canon 1.4xII on a 400mm f/5.6 lens, together in that order, and still had autofocus in good light. It was very slow, but it worked! The image quality left something to be desired though. I never expected that AF would still work at F/16.

Only the canon 1.4x is reported in the metadata, maybe that’s why it works, since it seems the camera doesn’t recognize the Tamron converter.

Nice to know that. Thanks for your views on the 2 useful but pricey equipment.

But you know Artie what concerns me most? Actually we are losing wildlife faster than we thought. As per BBC reports yesterday; 300 elephants (80% of total population) were killed in last year alone in the Cameroon wilds by poachers who are actually mercenaries. At this moment Cameroonian army is on high alert as there are reports they are returning to clean off the balance. In our country few of us are fighting hard to save the beautiful Spoon-billed Sandpipers that arrive in winter from Russia for survival. They are critically endangered species. We can only hope things will change for the better.
