[sarc] make sure to include a model-number scrambler so that, for example, an actual Sigma 'dp2 Quattro' becomes a "DP2q" [/sarc]
It was almost de rigeur over on DPR to change a manufacturer's model-number to something more 'normal' to the poster's eye. [sarc] It's creeping in here too, for example, "a74" which is so much more convenient to one's thumbs than "Alpha 7 mark IV" ... [/sarc]
The usual riposte to my whining was that it didn't matter so long as we knew what it meant. But Sigma screwed that up by using lower case letters for their later series of model prefixes. Some folks could not cope with that, in spite of the fact that a Sigma DP2 is a completely different camera to a Sigma dp2.
