I was wondering if anyone with a 7D and the Tamron 90mm macro shared my problem. When the camera (and lens) are set to manual focus and when shooting downward the camera changes to autofocus and tries - unsuccessfully - to find the point of focus. It only happens when shooting downward - not level or upward - hence, I'm thinking a physical connection problem rather than electronic, however, I'm really not sure what is happening? I still love the lens and the camera in spite of things though - nothing has come along to tempt me away from my 7D as yet although 6 megapixels is deemed din0saurish by most these days I suppose. Cheers!

Although I didn't get any replies when I posted this moons ago ... fyi ... it is the lens and not the camera. I just bought an A700 and the Tamron does the same thing as it was doing with the 7D ... Perhaps I will give Tamron a ring?

Very strange. I don't recall hearing of that kind of problem before (camera changing from manual focus to autofocus by itself).
