I know that effect. I just didn't think the Tamron would produce such backgrounds even in these circumstance. I'll have a look at some of my past shots.
After an initial period of getting to grips with the idea of a "superzoom" and its inevitable compromises, I wholly embraced the Tamron 18-250 as a great lens that has much more virtues than offering "flexibility". Too bad it went out of production.
