positive:Faster/more accurate focussing particularly on a99II
Excellent IQ even at f5.6 @ 400mm on a99II but fantastic at f8
Moisture and dust sealing
negative:Improvement over G1 version but for most only a small to moderate difference
comment:The G2 version for my use is a worthy upgrade given this is one of the lenses I use the most. When paired with better camera bodies like the a99II the difference in use is noticeable in both accuracy/speed of focus and also real world IQ. All round that little bit better. The 4.5 rating in sharpness is a comparison to the Sony 70-200mm f2.8 G2 SSM which is a little unfair but also the sharpness @ f5.6 400mm could be a tiny bit better for more use flexibility. A lot describe this lens as not having environmental sealing but it actually does - almost to the same degree as the Sony 70-200mm f2.8 G2 SSM (the only part that degrades this rating a little is the barrel zooming in and out however there is a much tighter updated seal compared to the G1 version). It has the same rear mount and button seals as the 70-200mm G2. Sony's website states moisture and dust resistance and I've seen one of these lenses partially disassembled so can confirm it does indeed have environmental sealing elements not present in the G1 version.
