We agree on most points, and I don't think you are against the dock. Rather, I think you are obsessing over minutiae that Sigma has likely already taken care of. I don't think either of us have had any revelations during this thread that Sigma hasn't already considered. If so, I'm surprised they do as well as they do!
I did claim that I would do the testing, and I also mentioned that I wouldn't be able to get to said testing until Sunday. Don't let the fact that I've plugged the dang thing into my computer lead you to believe that I'm in the same location as all my lighting gear, tripods, targets and space to do any testing. Everything is either in my office or in my car for an out-of-town wedding.
I assure you, I'll test it as thoroughly as possible. In fact, I hope to get some input from you and the forum on my methods, just to be sure all our bases are covered. I don't want my hope for the thing to work well to be perceived as any experimental bias, so I'll certainly lay it all out there.
No, I don't think you are against this concept at all. I just think you are jumping to a bunch of conclusions and that many of them, if true, would mean Sigma is composed of a bunch of idiots. I choose not to believe that.
I will tell you this much: If I put that lens on my cameras and Focal or Dot Tune suggests the same MFA for all focus distances, I won't be tuning anything. I'm very much in the "if it ain't broke" camp, and won't risk a perfect lens in the name of science!
