Hi,


Thanks for the welcome.


I mainly shoot smaller birds, although I use a hide (or the car) soIget fairly close to them and find that a 300 lens with one of the converters seems to do the trick.


However,I would love a 500mm F4, but feel that this would be the next stage after this decision. (I have thought about this, but if I brought this lens now I would have to stick with the 40D for a bit longer)
