steve, it does not matter who makes it, the laws of physics apply the same. those 28-300 and 18-100 zooms are very slow. notice i am not questioning sharpness or picture quality either. speed is enough reason to limit range. if you want 2.8 through the range that means that they have to make a lens big enough that at 300 it will be 2.8, and then mechanically adjust down from there. so picture a canon 300/2.8 and start from there.
leica once made a high quality 28-90, or was it 35-70, i can't remember any more, that was a true 2.8 through out. it was really big and very expensive, they ended up not making more because it would cost them too much to do it. anything smaller is a compromise. and usually the place where you compromise is speed. there is no way around it.
but if you don't mind an aperture of 6.3 or so in the long end, then the sky is the limit for you. i just don't see using something that slow as an ENG everyday lens. and i have been a news cameraman for over 25 years.
