Re: 200-600 A9 test at Airshow

Even though the chances you may get a bum lens among  the more expensive lenses is much lower than on cheaper lenses, you still can get an expensive bum/defective lens. Sounds like you have a defective lens. This lens is not built to make mushy images...unless it is a defective lens.

I just purchased a 200-600 and on my A7R4, the image quality at 600mm f6.3 is complete junk. It is mushy and I haven't gotten a single good image.

Is it just at 600mm that produces poor IQ, or other focal lengths as well?

For example, how is the IQ at 400, 500mm?

Keep us updated. Thanks.

It is the worst at 600mm but isn't great at any focal length.
