Tamron AF 55-200 mm f/4-5.6 Di II LD Macro
7. Coma and astigmatism
In this chapter we will going criticize first and praise later. The correction of the coma is not sufficient. The worst situation we see in the 55-130 mm range but at 200 mm it gets significantly better.
When it comes to astigmatism, though, the Tamron 55-200 mm reached one of better results among all lenses we’ve tested so far. The average difference between vertical and horizontal MTF50 values amounted to just 2.7%.
