Tested using an a580 at ISO200 shooting a still life. Images were cropped from 4912x3264 to 493x329 and compared.
@75mm the lens is solidly in last place compared to the 35-70 (sharpest) and 70-210 (nearly as good) at all f=stops, both center and edge.
200mm - at f5.6 a little softer than the beercan, but at f8 it's a toss up. At f11 the 75-300 is sharper. Blasphemy! But also true.
300mm - at f5.6 the image is soft with some serious purple fringing. The CA gets better at f8 and f11 but still present.
Colors are a lot like the beercan, as expected.
I did not test for flare, but the CA leads me to think it may not be good at 300mm.
Conclusion: Disappointing at 75 and 300, but surprising sharpness at 200mm, f8 and f11. I've mainly used this as a wildlife lens, nearly always at 300mm, and the results have often been disappointing. Now I see why.
