Got my Sony 15mm F1.4G and it produces horrible images

Was really excited about my new a6400 and Sony 15mm F1.4G when I purchased it from the shop over the weekend. Noticed some very minor green red edges on objects in the shop (was told it was normal - chromatic aberration). Some reviewers on YouTube mentioned it a little as well. When I returned home and tried to photograph a few things, the images were literally unusable - black text / edges come out as red to green hue. Felt really disappointed.

As I am really new at this, can someone tell me if the lens is defective or am I doing something wrong? Appreciate your advice!

The text here is supposedly black - not rainbow.

Edges of the lens cap near the light has this green - red hue.

Axial chromatic aberration

That appears to be axial or longitudinal chromatic aberration, which is common with fast lenses. Some lenses with a different optical design don't have this defect, but understand that a well-corrected lens typically is large, heavy, and expensive.

This defect will be reduced once you stop the lens down, or it may be fine if used with subjects where such fringing doesn't matter. Or, just don't pixel peep, and enjoy the image whole and entire from a reasonable distance.

I have an 85 mm f/1.4 lens with considerable axial chromatic aberration, but it is pretty much unnoticeable when I use it outdoors with nature scenes; the green fringing in the background blends in with the green out-of-focus foliage.

Unlike the common transverse or lateral chromatic aberration, this defect can't be satisfactorily corrected by software.

I'm wondering what you plan on using the lens for. Obviously, you didn't buy it to shoot reflective book pages close up at an angle, wide open. Did you buy it to use inside, low light, head shots, party shots?

Try shooting some samples based on how you plan to use the lens and see how it looks
