X3F file types - DPn versus DPnS - same or not?

For example: DP2 vs. DP2s?

All my Sigma DSLR's are compatible with all my various converters. Therefore, my current philosophy does not include SD15, Merrill, Quattro.

I am aware that the DPnX models have an AFE similar if not the same as SD15. So, not interested in those.

Thinking of trading or selling the SD9 for a DP1s or DP2s model but first I need to know that, for example, FastStone Viewer will open a DP1s or DP2s file without color cast, etc.

OT, but any comments about DP1s vs. DP2s lens quality would be appreciated.

fwiw .....some DP1s Raw files can be found in the last half of this page.

They do open in FastStone.

Never owned the DP or DPs series, but thought this was in "interesting" comment at the time, and put me on hold.........finally got an "M" series that I'm "comfortable" with.

Thanks for the links, Mike,

As far as i remember difference between dpX and dpXs coating on the lense and hot mirror electronics the same.

Thanks, Victor.

I've now ordered both a new DP1s and a used DP2s. Should be fun . . .

Yes, all DPN, DPNs, DPNx and SD15 are compatible.

The did change some meta data fields over time though, so maybe extracting color information varies.
