Suitability of Canon 10-22 mm EF-S lens for full-screen Kirt B. Witte Thu Jun 11 14:00:26 2009

Hi.

I have been using the Canon 10-22 EFS lens for panos for years... it works 
great!

There is a little bit of chromatic aberration, but its not bad... and can 
easily be tuned out via various CA adjustmetns in Lightroom, etc...
