Originally posted by magnusgraham How do you find the two lenses compare in terms of IQ, sharpness, contrast and bokeh?
For IQ, sharpness, contrast, they're fully comparable.
I have to use CDAF in live view
to get the best out of my copy of the Tamron at all focal lengths,
and for the wide end of the DA 20-40.
I find the DA 20-40 far superior, within its more restricted scope,
for bokeh, flare resistance, and general rendering.
There's an aesthetic pleasure to most of the Limited's images
which is rarely seen in the output from the Tamron.
