The 85/1.2 on the other hand is one of the sharpest and thinest DoF lenses you can get (without standing a mile away) but it's also one of the most outrageously priced lenses.
I don't think it's outrageous, it's just complex to build. Just check the prices of the new 56mm 1.2 Fujilense for the small APS-C sensors. Or check some other fast lenses... on Zeiss you won't even get an AF on it.
The point is to decide wether you need it or not. To build a sharp f1.2 lense is nothing you can simply calculate and throw into the market.
Here you could get a glue about the complexity of the Canonball: http://www.gletscherbruch.de/foto/85er/objektiv.html
Especially check the 72 balls to hold the glass.
