ownership:I own this lens
compared to:Sony SAL70300G
Minolta Maxxum 35-70/F4
Tamron Adaptall2 24mm/2.5
price paid:899USD(new)
Excellent Bokeh (check out my image in the samples gallery)
negative:Slightly soft edges at 2.8
Very slight yellow cast at 2.8, gone @ F4; would have given color a 4.5 if that was an option
comment:If the QC is variable on these, I must have gotten one of the best copies.
Sharper than the Sony 70-300G @ 70mm throughout the wide end of the aperture range, this surprised me. The Sony is very close @ 5.6 and about the same from 11 on.
Less falloff than the Sony at higher F stops.
Much sharper than the 35-70 F4 and very nice bokeh; unlike the 35-70.
Much sharper than the Tamron but that is a very old film lens that did not even carry the SP rating.

The zoom ring is smooth and the focus ring feels almost identical to the one on the 70300G, smooth and precise.
No zoom creep.
I wanted to give it a 5 for build but after reading the reviewing guidelines, I think only lenses built like the 70-200G would truly rate a 5.
