Can anyone tell which aperture is usable at which focal length? Or to put it another way, up to what focal length do I have f-stop 4?
F/4 @ 24mm
f/4.5 @ 27mm
f/5 @ 44mm
f/5.6 @ 70mm
f/6.3 @ 109mm

As impressive as the focal range of this lens is as unimpressive are the aperture numbers at various focal lenghts. One who uses this lens must make many compromises.
I rather carry 3 lenses to cover that focal range ...
I can understand some peoples aversion to this lens for the above reasons.
I'm not that serious a photographer. The vast majority of my shots are a f/8 or f/11, so these apertures are a non-issue for me.
Absolutely. The lens has a justification and will find its customers.
