Originally posted by jbcampbell I think I will be getting the new DA* 200 F2.8 instead of the Tamron zoom.
I'm debating that too... water/dust resistant that can be my one lens to use in foul weather, exceptional performance near free of CA & purple fringing, and hypersonic ring motor [! that's what got me thinking !] leading me to believe it'll be the fastest focusing of DA* lenses [accuracy?],
but fixed telephoto... vs... not water/dust resistant, unknown performance, legacy focus mechanism, but extreme flexibility in the zoom range it covers... the answer is TBD only after the DA* and Tamron ships and there are a number of test of both.
