I'm thinking about jumping into the Sigma camp, but am having trouble with info gathering...
From what I can garner from other forums, SPP has built-in lens profiles. What I can't definitively find out is what they're for and what is supported.
I've read that the profiles are used for CA correction, but don't apply any distortion correction.
I'd like to know if the CA correction is done per-lens, or if it's just a generic correction based on focal length?
If there are separate lens profiles (which I would hope!), which lenses are supported? I can't find anything which tells me.
Can someone here please answer any of this?
