I had the same problem with my Tamron lens and 90D. The lens was still under warranty so I sent it and the 90D to Tamron for calibration. Problem solved. It's not an unknown problem with the Tamron's and 90D's.  That lens is on my camera all the time!

It's a Tamron 16-300mm.  It's the jpg straight from the camera.  I had one image like this a few days ago.  Today I was at a nature preserve and shot about 250 shots.  I think three were like this.  Many good shots between the three showing this problem.  In looking over the bad images, the commonality appears to be that they were taken at the far wide angle end of zoom and are images with significant contrast in brightness... i.e. bright sky showing through trees in shadows.

I have shot with another fixed 100mm with no bad images, but have shot 10 times as many with this zoom.

Thanks so much for help with this.

Just for amusement for taking time to view... here's a good shot from today.  Little critter being gobbled is a lizard.  Same lens and camera.
