Lens correction software for non-Canon lenses?

Hi,

I'm aware of programs like DxO and its wonderful capabilities, but it doesn't seem like DxO supports many (any?) third-party lenses like Tamron or Sigma.

Have has anyone profiled their lens with ptlens (or something like it) and had good results doing correction?

Thanks!

Ptlens works very well, has a huge data base with many third party lenses and if your lens is not included you can request that he add it.

+1 on PTLens.
