I’m not sure if this happens with all lenses randomly or just this model.
I have 2 other lenses and have done testing in all types of light and different shutter speeds. However, the 50-230 consistently shows 2 blurry spots and I always have to edit them out. They are always there no matter what.
I bought the lens brand new and the glass is spotless and untouched on both ends and nothing visible inside (firmware was updated as soon as I bought it).
Here is an example I have circled the two spots. These only show up when I use this lens. Thoughts? Has anyone had anything similar happen?
