Originally from the Philippines, migrated in USA 1992. Got my first dslr canon eos t2i 2 yrs ago and got hook with bird photography just recently. Just purchased 7d recently to pair with my ef300mm f4l and 1.4x II tc, like others I really enjoy taking pictures of birds. I registered here to learn more about bird photography, found out this forum through Mr Arthur Morris blog/website.
Welcome to BPN, Peter. You are photographing with the same gear that I started out with. The 300 F4 and the 1.4 is a super combination, and I think you'll be happy with it. It's sharp and light. Looking forward to seeing some of your pictures. Hope you learn a lot here and have some fun too!
