OK, minuscule information on the Pixii. The color engine is still great. I would post some photos but we are having some Clatsop County sunshine today which means it is grey and overcast and drizzling. The color photos of my kitchen are just great but it is so messy you will have to take my word for it. I like the DNG color better than the JPG but that could just be the color profile. I will test that but may wind up just shooting DNG with M. Pixii. I have just shot at ISO 320. I will test that and the "Preferences" which are color profiles.
I now have an iPad which talks quite nicely to the Pixii. Strangely the iPad software thinks it can set the camera image format to GPR, a lossless 12 bit DNG format from GoPro GitHub - gopro/gpr: General Purpose Raw image format
I will test the Android connect with the Pixii to see how that is working.
Shooting speed: 9. It will shoot that many JPG's, DNG color or DNG monochrome before the buffer is filled. This is the same as my M9. It takes about the same number in seconds to write all the images and clear the buffer. I am just trying monochrome and have to find an editor in Linux, hopefully, which will look at them without whining.
Battery life. With WiFi on it is still a battery sucker. With it off not so much. Battery life is not a big deal for me so long as it is reasonable. I do not do big shoots of hundreds of images. And I have three batteries, they are cheap, so popping in a fresh one is not much of a cross to bear. My perspective is that replacing batteries is a small price to pay for the lovely color that I promise I will show you, someday. ;o)
In summation the Pixii is now better than it was without sacrificing anything. The upgrade was Euros 320 IIRC which is a good deal, add Euros 50 for return shipping and done.
