Quote:This lens has a 15x zoom ratio. Or in other words - any centering defect present at 18mm (center) will be magnified by this factor (plus minus a little) at 270mm.
I don't expect this lens to be perfectly free from decentering, but I guess it should be somewhat better in this regard than the stabilized version (which uses a mechanism that deliberately moves groups off-center). Don't you think?

The lens should last 5 years, after which I'll probably sell it and upgrade to something more up to date. If anything breaks earlier it would be very disappointing.
