The Tamron adapter arrived. Fits very nicely. :)
First comparison test against a cheapest of the cheap zoom lenses: Sigma 70-300 f/4-5.6 DG non-Apo.
Tamron seems to be just as soft as that cheapo Sigma... but Tamron has a lot more pleasing bokeh. Then again, the Tamron is a devil to focus :P
Both photos received exactly the same postprocessing. All the same settings, including whitebalance, contrast, sharpening. Noise reduction was Off.
Surprisingly different feel in the photos of these two lenses. :)
