bcalkins: I can't understand why full frame shooters are so worked up by this lens? When you buy a Canon 85mm f1.2 lens do you see what is available in other sensor formats, or do you evaluate what the lens can do for your photography and decide if it is of value to you? Do you see it as heavy, expensive and slow focusing, or as a tool that helps you get images that are like nothing else?
Who cares if this has the 'same' DOF as an f/3.6 FF lens? The question for me is if the DOF this lens offers compared to current MFT lenses is of value, and worth $900 and some extra weight. If you don't shoot MFT, why are you spending any energy thinking about this lens? It is the same question in any sensor format. Is it worth the extra money for the f/2.8 zoom over the f/4, or the f/3.5-f/6.3 consumer zoom, or getting a 35mm f/2 versus 35mm f/1.4 L. 85mm f/1.2 versus f/1.8? IS lens versus non IS (assuming you have a choice).
Am I going to buy this lens? Who knows, but I'm glad it is a choice. If we are smart we will make our decisions on what the equipment will do for our photography, not how it scores on dxomark.
