Re: SDQ Dynamic Range

The main difference between any Bayer sensor and the Q is not in sharpness but in tonal discrimination. In the first set look at all the color differences you can see in the grass and bushes in the Q shot and then notice how in the K1 shot the grass looks almost monochromatic in comparison.

I ran a quickie comparison test between my FF K1 + 31mm ltd lens and my SDQ + 18-35mm A lens set to approx same 31mm focal range as my Pentax lens. Same aperture, same tripod no sharpening but images adjusted for brightness. There was little difference generally but I thought that the SDQ images were a little sharper. Don't forget that the Pentax is FF and the 31mm is one of Pentax's best lens! I use the Pentax as an alternative when conditions or subject matter does not favour the Sigma. Both systems are excellent at what they are designed for. I suspect that my post may not clarify your dilemma but in reality I get more satisfaction from my Sigma. I do not find that the DR is much of a problem.

Wow, you're right - this does not help me at all! I much prefer the SDQ photos above to the K1 except for maybe the twine, but that had more to do with exposure. And, the K1 is full frame, with the Holy Grail of prime lenses. This says a lot for the SDQ. Hmm.

Wouldn't a full frame Foveon be amazing!?
