thanks for the links Joel


I have to point it out is that if you have ever been to La Jolla, CA, you know that cliff where people taking pictures of pelican is a very small area, so IMO a 300mm lens is more than long enough to take almost all kinds of pictures over there.my experience of using 300mm2.8+2.0TC II combo with 7D is that when the object is close enough, you will get very good results then when the object is far, it's hard to get good results. it is also hard to track fast moving object like turns in flight. so if you think you can use 70-200mm2.8II+2.0TC as your main weapon to shoot birds, think it again, egrets GBHs or ducks usually are hard to get that close like these pelicans.I think choosing pelicans in La Jolla for testing 70-200mm2.8II+2XTCII is very "smart".

but then Arthur Morris can take a lot better pictures, so it's just my 2 cents
