The beautiful World Heritage sites in Turkey - "Historic Areas of Istanbul", "Goreme National Park and the Rock Sites of Cappadocia", and "Hierapolic-Pamukkale" were captured with the Panasonic professional 4K camera, VariCam 35. This video introduces behind the scenes highlights during the shooting.
The tiny “4K Ready” camera from Sony - the PXW-X70 has been proving quite popular with documentary and event shooters given its small form factor. Apart from its size, the other most impressive feature in my opinion is the 10bit 422 Long-GOP codec and the fact that you can upgrade the camera to shoot 4K with the upcoming (paid) firmware in June, thus future-proofing your purchase.
