“There is a lens cap.”

Yes there is, but it’s difficult to attach and remove.

“The LCD can be adjusted to work well in bright light and for $10 you can through on an LCD hood.”

It’s one of the worst LCDs available and even when adjusted, it’s not all that wonderful. Plus, the fact it needs a ‘$10 hood’ only confirms that fact. Sadly, the DP2 is not significantly better.

“There is a viewfinder; just slip it into the hotshoe.”

The accessory viewfinder is not included and it’s also $150 (seriously, it really is that expensive).

“Adobe steers ACR and not Foveon or Sigma, so yell at them for non-support; they have had the code for long enough.”

Not according to Adobe, they haven’t. One of Adobe’s Camera Raw engineers posted on the Sigma forum that the delays were due to factors totally outside of Adobe’s control.

“Fixed focal length lenses rarely zoom, duh. But they are sharper and smaller. Zoom with your feet.”

Sometimes they’re sharper and sometimes not. It depends on the lens. Plus, zooming with one’s feet doesn’t always work.

Mr. Matson has also neglected to mention his ties with Sigma and that he does all of their printing for trade shows, and most recently he even can be seen working at the Sigma booth.
