Hmm, you didn't include the bokeh test results?

I rarely do so with wide angles ...

But you especially mentioned the bokeh, that is why I wondered :ph34r:

There is a truth beyond formal testing, isn't it ? :-)
Looking at the provided sample images (and the others in my stock) I'd say that the statements aren't wrong.
Is the panasonic 40-175 next ? Also are the measure MTF compensated for field curvature ? What I mean is do you show the mtf as expressed against the chart or do you adjust for field curvature and show maximum mtf (or does my question even make sense?)
-
Last but least (and unrelated) where is that post that talks about how to test for decentering?
(I never do say thanks but I really do like your reviews; though sometimes I miss the very old site that is long long long gone; you've been doing this a long time do you think you will continue or does it begin to get a little old?)

The charts show the MTFs on the focus field (which is the industry standard).
The field curvature of the 17/1.8 is not extreme in any case.
The test procedure for the centering is in the lens section (it's a stick thread at the top of the list).
There is a rumor that Panasonic 20 f/1.7 II will come out tomorrow.
