I blew them way up and they are somewhat soft, but, acceptable if you are not going to go much beyond 8 X 10. That's a good price for that kind of reach and flexibility. The Nikon version is much better but costs an arm and a leg!
He didn't say if he had already tried any sharpening on the images. If not, I suspect it can solve that problem.
I downloaded the flag image and tried to sharpen in LightRoom. At 100%, the star edges are a little fuzzy. But we are talking a $200 lens. It is probably good enough.
