I like the Olympus file system. I can set the aspect ratio and image style, like monochrome, in the camera and only save the raw files. This way I can see and compose the image in monochrome or any color style and any aspect ration I want. After loading the files into my computer, I can then make any changes I desire in aspect ratio, color, etc. I have Lightroom set up to load the raw files using the camera settings to see how they look as I captured them, and then make any changes I desire using Lightroom.
I like the overall size and weight of the Olympus micro four thirds cameras and lenses. I have returned, or sold, all of the recent Fuji and Sony gear I have been trying, and I intend to solely use micro 4/3 gear, at least this winter, as I try to determine what I will do going forward with my photography and blog.
The Panasonic 20mm pancake lens, shown on the camera, is particularly nice for a walk-about lens with the effective 40mm focal length. I made the rose image after the rose had been hit with frost. The colors of the camera-lens combination are nice. I just need to go out and find some suitable images to make with it.
