(For what camera and/or crop factor? For raw or JPEG?)

You can cook one up yourself using the Lens Profile Creator.

If you can answer the questions I pose, you might be able to find a community version in the Lens Profile Downloader.

I believe we have profiles for all currently-available (i.e., in production) Sigma lenses. Is the 19 f/2.8 in production? If not, that would explain why we don't have a profile for it. If that's the case, then it's unlikely we'll be providing one soon, but as John mentioned, it is possible to build one yourself using the free Lens Profile Creator.

You are right. It is a new model. I will check. I expect we will eventually have a profile for this (for use with raw images).

Only for RAW, why not JPEG?

It turns out we already ship a profile for this lens. It will only show up in the Profile popup menu when processing raw images. (JPEGs and TIFFs are an unreliable baseline for lens profile corrections, and the correction data is optimized for raw anyways.)
