So, what you're saying is, that the two 18-250 lenses from Tamron and Sony are both prduced by Tamron but slightly changed for Sony and a little faster !? (That should make it an easy pick :-))

I have actually been considering the Canon D500 with the AF 18-270mm f/3.5-6.3 XR Di-II VC LD Aspherical (IF) lense instead of the Sony a330, but I guess I have to wait to see some specs on the a330 :-)

Thanks again guys....
