After a minor (possibly alcohol induced) ebay incident I have ended up with a pair of A12 M-mounts rather than just the one i intended buying. This got me thinking, the unit is very good but for B&W work would removing the bayer filter like this:

be beneficial, or does the lack of AA filter mean most of the improvement is already there and losing the microlenses may be a bigger step backwards than the removal of the bayer filter is a step forwards?
thoughts?

According to the article, the gains aren't very big. I'd be concerned about losing the sensor's film-like qualities and the way it doesn't mask the "character" of the lense.

I suspect removing the bayer filter would be one step forward, but the loss of the microlenses above it be 2 steps back so to speak. At best I would get a barely improved upon sensor if everything went to plan, and a pricey paper weight if anything didn't! I was just interested if anyone else had gone down this route at all (google didn't help, so I thought I'd ask).

I don't understand why this would help much. The camera's image-processor would still "de-bayer", since you will probably not manage to reprogram it, would you?
So, the camera would still assume the Bayer filter in place and would do the same resolution-reducing calculation that assigns a red, green and blue value to each single pixel.
Once I found someone who offers modified Canon DSLR without Bayer; but I don't know where that was.
About the need of anti-aliasing; you just think if the resolution of your lenses is high enough to interfer with the pixel size.

The camera Bayer processing would only happen when the final output file is jpg. If the output result is raw, then that file has no interpretation associated w/. The problem is that this raw file cannot be developed using normal photo sw programs. U need a sw that knows to interpret the raw data as a monochrome dump.

Digiloyd did one of the better writeups about this w/ a Nikon d800 that had been converted to monochrom.

He used a sw package call Accuraw monochrom.

Software is not an issue, there are a few suitable packages out there.
I just wonder if it's worth the risk. I get the feeling that the short lens to sensor distance of the Leica setup will be a bigger issue than say that nikon if the micro-lenses are removed.
Any one know who makes the sensor?
