You're not seeing ordinary lateral chromatic aberration, but longitudinal chromatic aberration, which occurs in front or behind the plane of focus with fast lenses. Both types of chromatic aberration will be zero in the centre of the image at the plane of focus. In this case the image is slightly misfocused, which is common with phase detect autofocus and ...

As a rule, 50/1.8s (or pretty much any 50, for that matter) are very good lenses. Price isn't too good an indicator of quality for 50s- a company's f/1.8 design can be optically better than its f/1.4. Your 50mm is almost certainly better than your zoom lenses. Testing a lens wide open and at a close distance is going to show it at its worst.Have you tested ...

I think what we see here is not the traditional lateral chromatic aberration. This is appearing in the center of the image, in more or less blurred area, the color is blue and purple and is dependent on an f-stop. I think it is a combination of axial chromatic aberration and spherical aberration. Some thoughts: This is probably shot at very short ...

I agree with @ElendilTheTall, what you are seeing is not at all uncommon in this price bracket. Just to extend on what has been said - with regards to the PhotoReview test you mentioned: if I read the EXIF data included with the tests these were measured at f/5.0. In which case I would say they agree with your images. I don't think the lens is faulty.

Chromatic aberration of this kind is not uncommon in consumer lenses when shooting wide open, and it appears this lens is no exception. You will need to be looking at paying at least five times as much for a lens that doesn't exhibit it to the same degree. No wide aperture lens is at its best wide open in any case. Fortunately, chromatic aberration is very ...
