Solid, but new Canon alternative promises more

Had the Tamron Wide perennial in occasional use.
When shooting buildings and interior shots of people in confined spaces.
And I've rarely maxed may still gradable sharpness by stopping down.

Conclusion: Solid, effective for a wide-angle lens with a good price-performance ratio.
Core strength is the focal margin, the more opportunities can in Street Photography than with lenses that already stop at 20 or even 18mm. Also, some of the competitors are fainter, as the Sigma 10-20 / 4.0-5,6

Now I will however replace it with the new Canon 10-18 STM. Although it has less focal length (which is then lost, unfortunately) and is kunststoffig, but the benefits lure: It costs half, 1/3 is lighter, shorter, thinner.
The 77mm diameter from Tamron are already a measure and the lens hood is again (to) dimensioned very abundant, like jammed in the camera bag. And anyone who has ever experienced the inaudible and lightning-fast autofocus of the new STM lenses Canon APSC, knows what I'm looking.
