First time with this lens, a Tamron 70-300 on the K5. I have used it a great deal since 2007 on K100d and K20d. It has always focused very well. I never considered it would do any different on the K5. Well, it back focuses quite a bit and therefore I know what I will be doing tomorrow.
Taken at Donna Nook, just south of Grimsby an the east coast of England.
