OK, they take nice pictures but, after playing with my newly acquired DP1s and DP2s, I find it quite cynical that the DP1s comes with a DP1 manual and a scruffy fold-up sheet in a hundred different languages with the English bit spread across several folds to tell us the differences between the DP1s and it's predecessor.

But then, examining a raw histogram, I was amazed to see that the maximum raw level attainable with these two cameras is around 2,300 !!

I mean, the SD9 raw values can be up in the 10,000s the SD10 even higher, then the SD14 more like 9,000 and the SD1M more like a sane 4070 - which almost bears a resemblance to th

What do you mean by the term "raw values?"

e ADCs output. God knows what the Quattro puts out, something different, I'm sure.

With scaling variations like this, and the X3F format changing with each new model, it is small wonder that so few converter providers have anything to do Sigma's products.

I actually bought these two cameras thinking they would be no different to the SD14 (same sensor, right?). Ha, how naïve can one get?!!

A storm in a tea-cup, you might say - but every time I open an X3F in RawDigger, I now have to set the over/under exposure levels to suit the stupid camera used. Ridiculous!

Wouldn't that be the case with any camera? Setting different levels is the essence of shooting in RAW.
