. . well after a couple of beers, I'm beginning to wonder!

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 the 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!

Ted,

Maye you had too many beers. What difference do the values make if the cameras produce decent photos and they all do. Getting bogged down with theory and figures never produced an image and never will.But then. I suppose we all have our own particular interests in the photographic world.

Having said that I wonder if any other camera & sensor type is so endlessly analysed as the various Foveons are.

SPP is a good converter for all X3F files but it would be useful if the later cameras RAW files could be opened in e.g. ACR as they could be up to the SD15. (I know you do not like Adobe). Handy at times and faster than SPP especially SPP 6.2.1 which is excellent but slow especially with SD1 & Quattro files.

Get happy again soon,it's better for all round health.
