Spend less for a better lens of the same type: a Minolta Rokkor 40/2, which is a copy of Leica's Summicron 40. In M-mount, and of course a focus ring. Wonderful images.
rgibbons: Is the flat lens efficient at passing light? My camera lens with coatings can pass over 95% of the light. Do the flat lens antennae block some light, and are less efficient?.
Note that the research was funded in part by grants from the National Science Foundation and the Air Force Office of Scientific Research. Commercialization and the bulk of the profits after a small royalty to Harvard University will be taken by Google and other corporations. Same story as with many of Apple's "innovations."
Ingemar Edfalk: "I will have the camera set to the AdobeRGB color space and not sRGB, which is better suited to JPEG shooting. AdobeRGB gives a wider color gamut..." As far as I know this is not correct. The RAW file is not an RGB file. The choose of colorspace comes later in the conversion to RGB. The posibility to choose in camera targets JPEG shooting.
The author wrote, "AdobeRGB gives a wider color gamut, and is the best option for raw images that will subsequently be edited on a computer."
Just underlining how badly the author misunderstands raw files.
Third-party MF primes are so much more effective and fun on a Fuji XE-1. New firmware allows min shutter speed to trigger ISO increase. Mag rocker button is immediate, 3X and 10X. It's an APS-C camera, but a Voigtlander 21/4 works fine on it.The reviewer gives details that make his case about the Sony. Sony is a new-tech gizmo company, not a camera company.

Charles2: In Etchells' second paragraph we learn the factory is only 90 minutes by car from Fukushima, ground zero of a nuclear disaster slipping toward an even more disastrous sequel. Ah, the radiation!
Nothing negative about Sigma intended. If only the nuclear industry had the same attention to detail, Japan and the world might have been spared the ongoing disaster emanating from Fukushima.

In the film days, did newspaper darkroom staff routinely dodge and burn?
In the digital era, if you forbid any change to a camera JPG, you choose a style set by the manufacturer - Olympus colors, Nikon exposure, or whatever.
YetiYeti: Raw Therapee seems also an obvious candidate for this comparison. In latest V4.0 edition, it is stable, fast, free, and becoming more and more Lightroom like in workflow and experience (but has no "catalog" concept, like Lightroom) . In some cases I get better results with RT, than with Lightroom. It even supports Adobe lens profiles. Available for Win, Mac, Linux.. 32 or 64 bit... Lively community participating on their forum too.
If you find it hard to believe, go and try. I have no affiliation with them, I just admire their work...
Raw Therapee exposure adjustments can be very precise, .01 stop if you wish. All its exposure and brightness tools together bring just about any image (raw file or TIF) into appropriate dynamic range.The LAB curves are another fine RT tool.
"in a Foveon sensor, every pixel captures a true color because the red, green and blue filters are stacked above the light-gathering photodiodes."My understanding is that there are no such filters in a Foveon sensor. Light travels deeper into the silicon depending on its wavelength (color); the readouts gather the intensities at several depths.
The K-5 has been wonderful and will remain so for me. Evolutionary changes will serve new buyers well.
