I wouldn't take the distance information in the Exif-data too serious.
(this is not a distance-meter ... its just a lens).
Compare an image that you focussed with AF with one that you
properly focussed via lifeview, and see if there is a difference worth
mentioning.[/quote]
Well, I suppose for contrast-based AF calculation of the subject distance is in a sense just a by-product. Anyhow, what I do take serious is the lack of sharpness, my sample of the Tamron 70-300 VC is obviously defect and will be on its way back next week.
