Re: Copy variation: which one should i keep?

This is what i see: Sample A has better center sharpness ( also better t'han My 20-50,and My 16-50pz) but the smallest sharp center zone. It performs exactly How is expected based on review around.

Sample B is sharp from corner to corner at 18mm f3.5 and that is anomal to me. It is on par with My 20-50 at 20mm and better t'han the pz at 16mm. It keep the same edge to edge performance but after 45mm it the center becomes less sharp t'han sample A. Also i see a lot less CA in this Lens.

Does anyone see the same?

I am humbled because sample B looks a lor better exept 55mm where it needs to be stopped down or just not zoomed that far..
