Query: Awful chromatic abberation

As they say, you get what you pay for. This is true for lenses. The chromatic abberation on this lens is very bad, to the point where it ruins the shot, as it is very difficult to remove even with Photoshop/Lightroom. There is chromatic abberation throughout the range and view, even in the very middle. I know it is a cheap lens, but this one aspect of it makes it not worth it for me at least. The sharpness is about average. Focus is loud and slow. The construction quality is very cheap. Even though there is very little, if any, barrel creep (lens extending under its own weight), as it is very light, the barrel is very choppy - it does not rotate smoothly. The switches have a very tacky and cheap feeling. I would recommend pitching in more and avoiding this lens, or getting a legacy Minolta on eBay.
