I do love the 40s. I think that's why the 43 has been less compelling for people.

You make a good point here.
The issue with monochrome conversion is paucity of data. Even best case with RAW capture on most dSLRs, we are talking a 14 bits of data, meaning 16,000 (214) gray tones in the palette. That sounds like a lot until one starts working with an image in PP. A lower contrast original may provide an advantage, though I will confess to not having done any comparisons. In general, I try and start with a color original that has characteristics of what I want to display in the monochrome conversion.

I think we take on board cues from dof a lot more subtly than we realise to see 3D. In other words we use slight changes in sharpness to augment the stereo purpose of having two eyes much more than we realise. I use smart sharpening a lot (edge sharpening) and the Gimp process I use gives me options to not sharpen areas. This is a great way to gain a bit of 3D pop. I don't think it is the sharpest lenses that lend themselves to this but rather the slightly softer ones like the M40 2.8. which responds well to the sharpening process.
