Hi Ben,
if f/8 is the maximum perture for this lens, it might just be rated a bit
optimistically (many are). You might try the same comparison at f/16 or 22.
Furthermore, the f-stop doesn't directly define the amount of light that is
transmitted through a lens (and thus the shutter-speed). Transmittance is
influenced by the total amount of glass, number of air to glass surfaces etc. as
well.
I guess, whether it's a junky lens or not depends on whether you like the
pictures it takes. And carrying a 600 around certainly saves on expenses for
body-building ;-)
Cheers,
