In post, I'm cropping out massive portions of the tops and bottoms of my images. I'd love to be able to select a 3/2 or 16/9 or even wider on my Pen-F without losing pixels. I've just read about the multi-aspect sensor on the GH5s: Panasonic Lumix GH5S preview - Cameralabs. In addition to cutting out pixels on the top and bottom, the implementation also adds pixels wider than normal to preserve the number of pixels exposed - for many crops. This implementation doesn't impress me as being Rocket Science. It seems to me it's something that could be implemented in the camera firmware for any m4/3 camera. Where am I gone astray here?
