ownership:	I own this lens
compared to:	Sony SAL70400G I
price paid:	AU$700 USED
positive:	- cheap (AU$700) - easy to zoom - Reasonable AF speed - good size and weight - sharper than Sony SAL70200 especially on tele end (in memory) - somehow the focus limiter works on my a77ii, unlike other reviews said
negative:	- purple fringing at f2.8 - Ugly Sigma old design. The new sigma design looks much better but never make it to the Sony a-mount. - missed shots because of the reverse zoom ring - front focusing issue - OS is useless on a77ii, however it works pretty well on a6000 - weird colour Updated: 02/11/2020: Horrible ghosting flare ruins the entire photo. The coating was suck.
comment:	As above. Easier turn the zoom ring than SAL70400. A good alternative when doesn't need a tele range and larger aperture. Great and much cheaper combo with a6000 + EA4 because of the lens-based OS. Updated: 02/11/2020: Horrible ghosting flare ruins the entire photo. The coating was suck.
