Sigma sd Quattro: Overview after 4 years of use!

Finally, I take a look at my old-ish friend, the Sigma sd Quattro. What is this thing, anyway? What makes it special?

Today we look at the Sigma sd Quattro, another camera that doesn't get the attention it deserves. It is really not for everyone and everything, and doesn't hide that in the slightest. So, what makes it interesting and what are the physical features? Let's take a look!
Please note that this is not a review; we will not be exploring the Quattro's capabilities yet. We're just taking a look at it and going over some technical stats and the body.
Spoiler: It is awesome. But not for everyone.

--Technical with links:---------------------------
Video and photos of the sdQ shot with a Sony a65, using a Sigma 50mm f1.4 EX DG HSM , an old Sigma 24mm f2.8 Macro, and the venerable Minolta 35-70 f4 Macro, the OG AF kit zoom.
The SD card used is from Lexmark.
Tripod is a Manfrotto I picked up at Goodwill for $6. Steal of the century.
Audio captured through an Audio-Technica MB3K, Behringer Xenyx 1202FX, and EVGA Nu Audio PCI-E sound card.

Video was put together and rendered in Blackmagic DaVinci Resolve. If you can use Capture One or Lightroom, you can use Resolve. It's super easy to do the basics and super powerful. Just have at least 16 gigs of RAM and dedicated graphics and you are good to go.
