• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

A week ago I decided to give the Tamron SP 15-30mm f/2.8 Di VC USD a chance based on the great reviews it gets all over the net. I have not been disappointed so far.

My question is this: Where do I find the lens aberration data to load into my camera? Is this even possible with a third party lens?

I've looked all over the net and cannot find anything about this. My cognitive ability isn't what it used to be either. For the past 6 months I've been having a lot of trouble remembering things and learning new things. That might be part of the problem too. I'm only 52, but it can be scary getting older.

Any help would be appreciated. Thank you all in advance.
