I\'ve had this tc for about 4 years, but since I had no lenses that would auto focus on my 7D with the tc, it has remained largely unused. Taping the pins did not help. When I purchased the 500 F4 II, I thought I\'d give it another try. It still did not work properly, so I sent it to Canon. Since I got it back, I have not had a month or so ago, I have not had a chance to give it a work out, so this morning I went looking for some migrating boids. I found some Ringnecks in the same lake as last year, but they were skittish, and since I had no food, I couldn\'t get them as close as I\'d like, but that did not stop me from shooting.
BTW - the tc seems to work, but reports the F stop as \"0.0\", and it switches between \"AI Servo\" and \" Manual\" by itself...
So here are 5 shots including a bonus gull flyby.
