Can't believe someone is arguing in favor of an 85 1.2 + 1.4x. That would be the most awkward shooting experience yet. It's so front heavy that it would probably snap the teleconverter right off. When we were kids we had these inflatable toys that had a weight at the bottom, and you could hit it and it would bounce back up. Not sure what those were called, but that lens combo reminds me of that.
These:
Not to mention that the 135 is a lot better wide open than an 85 + 1.4x, it's a lot cheaper, faster AF, and personally, I like the look of the 135mm to the point where I just sold the 85 about 5 years ago. The 135 is still one of my most used lenses in spite of it's notoriously inaccurate AF. At $1k, that lens should be in everyone's bag.
If they added IS and managed to improve IQ, I would preorder.
