[quote name='Klaus' timestamp='1315381462' post='11364']I do not advise this method for (ultra-)wide lenses which have a (negative) field curvature issue.[/quote]
Doesn´t the field curvature issue disappear when the lens is stopped down? I think this was the case for the Tamron 17-50 mm f/2.8 lens, which however is not ultra-wide.
