And yes, the sensor has the APS-C format - and what kind of a sensor! DxOMark sets him not in vain over all (!) CANON EOS DSLRs with APS-C sensor, so using the 7D and the 70D! I can only confirm this, the image quality achieved loose high-level DSLR! All the more astonishing, however, is the very practical, because at 24mm (KB) starting Zoom in conjunction with the optimization algorithms camera own. Everything is taken out! This only works in JPEG mode and not in RAW images, but one thing I can assure you: the out of camera JPEGs are so good that for the first time I have the feeling here having to edit anything afterwards with Photoshop (of crooked horizons and film editor apart). In fact, I even recognized a good prime lens (30mm SIGMA) sold again because the lens brought no profit over the zoom. I've tested both in detail and can only say that the optical image stabilizer in the kit zoom the lower initial light intensity makes up loose again.
What remains to criticize: the handling! Those who come from a DSLR, which will initially feel repulsive the SONY typical, extremely strange sort of user interface. But you get used to it, and something must be seasoned DSLRs indeed better ... for this I would like to have deducted half a star.
Conclusion: Absolute buy recommendation for people looking for the highest quality in the smallest space!
