Just having some fun at my window blind. Shot with the 400L and all 3 Kenko tubes on it from 4.5 feet away. :D

Really nice! It's a shame some of the legs are cropped out but the last one works really well. He's looks very inquisitive.
yeah it is a shame about the lack of legs. great shots though all the same, you can really see the individual feathers and get a real feel for the texture.
fluffy little fellow :D
His legs wouldn't have fit in the frame. These are full frame shots with a 400mm telephoto lens but with Kenko tubes behind it to reduce the focus length. Sort of like Macro with a telephoto. The normal minimum focus distance for the 400 is 12 feet. With all three tubes atached, it brings it down to 4.5 feet. It was just an experiment. ;)
nice pics geezer :) ...up close and in your face.

Thanks David, that's what it's all about. ;)
i don't really understand how you manage telephoto-macro, but i'd say it worked!! sounds pretty clever to me :)
It has to do with the normal focal length of the lens, the distance from the rear element in the lens to the sensor/film plain. The way they make zoom lenses is by making a variable focal length rear element in the lens body.
If you remember those pics of how a lens works, you can kind of picture it. I drew a pic below to show what happens. Normally, the lens is made for the camera, they know the precise length of the rear element in the lens to the sensor. By adding these Kenko tubes, it changes that, moving the rear element further away, the light with it's image spreads more but the sensor stays the same size, just catches less of the picture, so in effect, magnifying it. ;)
