The drawing above shows what Canon’s rival to the GH5 will look like. It is based on the form factor they introduced with the XC10 but features several ergonomic improvements and an interchangeable lens mount. The lens mount appears to support EF lenses and has a locking mechanism. However there seems to be even more going on with the lens mount than meets the eye.
The A7S is so close to being a ‘complete’ system for high end video quality in a small prosumer camera, but there’s one issue that has quite rightly been highlighted by filmmakers such as Andrew Wonder and that is the rolling shutter distortion. The A7S actually has a very fast sensor with high efficiency made possible by the latest technology but because it does not skip any lines when reading out the image the net result is a scan that takes roughly as long as the older 5D Mark II, which does line-skip.
Sony plan to fix this by introducing a new sensor technology which can read entire lines of pixels in batches of 4 simultaneously.
The Taiwanese manufacturer of the iPhone 4’s camera, Omnivision, are producing a small sensor that features a global shutter.
Sony meanwhile have patented new type of lens with liquid elements which vary in shape depending on an electrical charge being applied. This makes possible ultra tiny optical zoom lenses.
