Add two more new birds spotted along riverway:)
Great Blue Heron. I have saw this bird before wandering around, but just caught it this time.
Female Northern Cardinal. I also saw similar bird before, don't know whether it is the same bird. Singing 很短促的 high-pitched "叽叽”声,extremely shy. 可惜有些虚了- colder98

My canon 1.4x extender doesn't AF when it connect to my 100-400mm head. But if I get enough time to MF the object, the sharpeness will not be affected.
It will be a big gun when you carry the 400mm plus a ring, and 300d body.
you probably need an assistant.- pbxmeis

400 DO label price is 6 grands. Who has the money for it?
I guess the point is, dawn used kenko extender. Usually the compatible products from the third party have some unexpected surprise.
There is a trick I never tried, which can make the canon 1.4x extender work AFly on 100-400mm. Maybe I should test it.

Colder98:
NOD NOD。I am not that richJust 400mm/f5.6. Used kenko extender to hope it still can AF. However, it only can AF with the 1.5x, can not AF with kenko 2x. Some people said to tap the contact to fool the camera, but I don't know how to do it.
I was attemped to your 100-400 lens, as sometimes it is very difficult to look for the bird with the 400mm lens, so it can not AF with canon 1.4x? may be sometimes you can try my 1.5x to see whether third party works:)
You are soto do manual focus, I have tried with 400mm and 2x, but was not good:-(
And it is getting very heavy if I put all my lens in the bag. You know somebody willing to volenteer to be my assistant???- dawn256
