You left out the most important video feature--and it is unique on this camera. There is no more time limit on videos due to the file limit size of the FAT-formatted SD card. The GX-8 seamlessly starts a new file when the limit is reached. This is essential when videoing classical music, where the sections can be quite long. It also relieves the photographer of a lot of worry about performance times. see https://www.youtube.com/watch?v=CRxR-LxE1iQ&feature=youtu.be for a 4k example.
thomash2: I want to contribute an article about spherical panoramic photography which I think would compliment this article, I even emailed email@example.com my 1st page draft of 3 pages, but no one replied!!! It would be an article about how to create photos like these, with seamless stitching and a complete 360x180 sphere: http://www.thomashuang.net/nz2/nz2.html
I love your pictures. Please write up your method and post a link.
