To provide photographers with a broader perspective about mobiles, lenses and cameras, here are links to articles, reviews, and analyses of photographic equipment produced by DxOMark, renown websites, magazines or blogs.
Launched in September 2012 the Fujifilm XF1 is a fixed lens compact aimed at advanced enthusiasts after a pocket-sized second camera for holidays and photo day trips. Featuring customizable function buttons, creative exposure modes and a manual barrel zoom lens with a 25-100mm equivalent focal length, there’s plenty of control for serious photographers to sink their teeth into. What’s more with a 2/3-inch 12-megapixel EXR-CMOS Sensor at its heart we’re optimistic the $499 Fujifilm XF1 will deliver on picture quality, too.
Announced this January at CES 2013, the Pentax MX-1 is Pentax’s first foray into the relatively crowded field of high-end-compact cameras. With a 12-megapixel, 1/1.7-inch backlit CMOS sensor, the Pentax MX-1 competes directly with established high-end compacts like the Canon PowerShot S110, the Panasonic Lumix DMC-LX7, Olympus XZ-2 iHS, and Nikon Coolpix P7700 among others, many of which have already been through multiple updates and iterations.
This year’s theme for high-end compacts is undoubtedly the switch over from CCD to BSI CMOS sensors, but maker’s are having to work hard to make the cameras attractive to those users who might also be tempted by interchangeable lens based mirror-less models. Olympus’ upgrade to the original XZ-1 sees plenty of promising features including the new 12-Mpix BSI CMOS chip, but how well does it fair in our exhaustive tests?
It has the same sensor, so your "advantages/disadvantages in tests" are just your own measurement errors, well within your margin of error (see your comparison of Fuji X10 and Fuji X-S1, Oly E-M5 and Oly E-PM2 - sensors and processors are the same, your ISO scores differ by 10-20%). But P7700 has slower lens, chosen to be slower to provide longer zoom range. So the choice is do you want better 28-112 (XZ-2) or better 130-200 (P7700) for which you don't need to crop (113-120 or even more I guess as good or better on Oly even with a little crop due to faster lens at 112).
Thanks for your comment. It pretty much corresponds to our conclusion. Nikon takes the lead thanks to a wider ISO latitude but basically differences in IQ should not be noticeable on your final images (as noted in our comparison review).
It is worth noting that DxOMark sensor score only takes into account sensor quality.
