Summary: I'm a long time Minolta user and unconditional supporter (since 1971 : 3 SRT 101, 1 XG, 2 Maxuum 9000), and did enjoy a lot the five Sony Cybershot , so when Sony released its Alpha 700, I went for it with a SAL 1680 (SN 3823746),,,, and I did appreciate to be able to use again my 300 mm, macro lens, fish eye etc..., and despite its apparent weak/flimsy construction, I really enjoy also the sharpness of the Zeiss lens......
Pros: Sharpness and apparently a good deal price wise
Summary: This is a nice lens that covers an attractive zoom range. It is nice and sharp all around with good colour and contrast. A good walk-around lens. But at this price the build is a little embarrassing. The zoom creeps down when only slightly turned downward. Sony should fix this problem.
Pros: Sharp at most settings, nice colour, nice range
Cons: Poor build, zoom creep shouldn't happen for this price!
