ownership:I own this lens
compared to:- Minolta 28-135
- KM 28-75 f2.8
- Sony A7 kitlens (28-75)
price paid:50 Euro
positive:- It's a compact lens and focus quite fast.
- Not as sharp as the 28-135 bearcan or the KM28-75
- 24mm is excellent
negative:- Beyond 24 mm it must be stopped down
- Long end is rather soft.
comment:Tested on the A7 with my second copy of the 24-85 (first one had some decentering issues).
I'm impressed by the 24mm, sharp corner to corner at f4-f4-5. However beyond 24mm it's not as good and the lens must stopped down to f5.6 for some decent corners. On the long end (50mm-85mm) it's rather soft and the lens must be stopped down to f8.

The lens is supported by DXO Optics and I recommend this software. It fixes the barrel distortion and vignetting.
