So is this a naked sensor and no filter on the lens also? It looks promising for color, maybe a few IR cutoff filters for your lens is in the future.

Reminds me of making false color composites with old LANDSAT images. (LANDSAT 2 & 3).

Very cool looking to see how it would look with no filter. It has an almost Aerochrome feel to it.

And I like the image itself with it composed looking down the road, I enjoy road and pathway images.

Thanks. Here's a screenshot from the Sigma proprietary converter, showing the dominance of red with the blocker removed.

I found the RGB conversion by RawDigger's LibRaw to be less drastic for many shots.

I gave up on the Sigma IR because of the lack of live view and got my Lumix DMC-G1 converted instead ... night and day ...

Sorry, I missed the question. Yes, on the Sigma DLSR cameras, there is a so-called "dust cover" in the camera's lens mount which is in fact a dichroic UV/IR blocking filter. It is easily removed by one's thumbnail and can be replaced almost as easily. As to cut-off filters on the lens to replace said dust-cover, that's not so easy because dichroic filters are incident angle-sensitive, e.g. B+W 486. I've tried various normal filters e.g. green, yellow, red and they can help, especially when going for the "AeroChrome" look ...
