If you go to the end of the thread, there is a downloader for various
profiled lenses.
thanks for the tip; here's a more direct link to the downloader:
<http://labs.adobe.com/downloads/lensprofile_creator.html?PID=4079915>
it is an AIR app, but i already had to submit to AIR since i have my Adobe apps
via subscription now ...
with the downloader i was able to find profiles for my A 50/1.7 and FA 28/2.8;
would really like to find one for Sigma mini-wide 24/2.8
the 50/1.7 profile does a very small distortion correction, but a bigger
vignetting correction — suprising; the FA 28 had substantial vignette and
distortion corrections
note that some of the profiles got mediocre or poor ratings, though there are
usually no comments as to why the rating was deserved
Igor — there is a DA 17-70 profile listed, with a rating of 3 out of 5, but not
18-250
