Tamron SP AF 17-50 mm f/2.8 XR Di II LD Aspherical (IF)
7. Coma and astigmatism
Real purists could complain slightly about the coma, which is visible but only with the wide-open aperture.
The astigmatism correction leaves us nothing to complain about. Tamron’s designers can be quite proud that its astigmatism reaches a very low value of 2.5%.
