Hi all. Finally bit the bullet and bought an x. It's just arrived and is sat in my lap as I watch tv, drink beer to celebrate and try to look through the custom functions. Different to my mk 4 I must say, chunky, handles great and very easy to look over. Top quality as expected. Anyway, I'm off to work tomorrow then it's holiday in Venice, seals, deer and Griffon Vultures. Taking the old 1ds3 to Venice but it's the bird stuff I need help with. My mk4 is set the way I like but the x? I just don't have time to practice before I'm off shooting. Any x owners got any advice on set ups for birds in flight, big birds pretty predictable but still fast and big slow deer. Any help will be very much appreciated, I honestly just don't have time to set it up. I'll compare the 1ds3, 1d4 and the x as soon as I'm back. Now, back to annoying the wife .
