absolute nonsense. old nikon lenses are not 'completely incompatible'
at all. they work just fine, just with some limitations, depending on
the camera. most people who buy an entry level slr don't have a bunch
of old lenses anyway.

compare that to canon where old lenses *are* completely incompatible
because it's a totally different mount.

The adapter for Canon FD lenses unfortunately includes an extra
element that considerably degrades optical quality.

But apart from Canon's own legacy mount, it's true that you can use
many other types of lenses on Canon EOS cameras. I have successfully
used Carl Zeiss (Contax), Leica R, Pentax (K bayonet and M42 screw)
and Nikon F mount lenses on my Canon EOS 5D. I currently use a
mixture of Canon and Nikon glass, plus one lens from Samyang in Nikon
AIS mount.

So buy a Pentax! Canon Teleconverters don't work on their EF-S lenses
either...

Pretty good "bang for the buck" is Tokina's 80~400 lens (AF-D 80-400mm
f/4.5-5.6 ATX 840) , is inexpensive (USD $499.99) because it doesn't have VR
or an internal focus motor yet, but I think they'll launch a focus motor
version at the spring PMA show. It's 1/3 of the price of the 80~400 Nikon,
and 1/2 of the price of the Sigma.. You'll have full exposure control, but
no AF (with the current version) but a teleconverter on you 55~200 wouldn't
reliably AF either.

cheap lens (optically not a top performer)
zoom lens (more compromises in optical performance)
probably not good teleconverter (optical performance suffers)
2x teleconverter (strong impact on optical quality)

Do you see a trend here?
