impossible to get ideal micro adjustment
|comment:||Since getting a A850 i was looking for a FF equivalent to the CZ 16-80mm and sadly i don't think there's quite a match on FF but this tamron does a reasonable job but ultimately (other than build) the CZ out classes this lens in everyway (sharp wide open, faster AF, better bokeh etc). That said the CZ is at least double the price 2nd hand so long as you can live with the slow AF and image quality closer to the 18-250mm then you'll be happy with this lens.|
One of the problem with this is there's focus shift so it's impossible to set a micro adjustment that's ideal throughout the zoom range, squeezing the best out of this lens at the long end can mean you get softer results at the short end and vice versa. The issue is most pronounced when you're shooting wide open so in the end I've decided to optimise this lens for shooting at f5.6 which in my case needed a -13 micro adjustment.
Despite all these buts I still think it's a worthwhile FF lens, or rather all the alternative walkabout lenses have their own share of drawbacks such as long MFD, CA, worse range etc in the case of the minolta 28-135mm/35-105mm.
