Image quality is amazing. 20x30 inch prints are crisp, even up close. Most importantly, the image is completely devoid of Bayer's Demosaic artifacts. These are those fun color patterns you see in photos of blinds or areas of fine texture like gravel. Most people don't even know what they are until they see an image with Sigma and realize how much better the image is without it. Even the best regular DSLRs have these artifacts. To get a camera with truly equivalent image quality, you really need to upgrade to a 40 megapixel medium format camera, like a Hasselblad. It'll cost you $25,000 for the body and a lens. Many reviewers complain about the ergonomics, especially the slow recording to the SD card. In most cases I didn't find this to be a problem because the 7-frame buffer means you can take the next shot immediately. With this camera, I have the controls I use all the time, aperture and exposure, right in the palm of my hand. It's a pleasure to use. In good light, the autofocus stops every time. The short battery life is a little annoying, but the batteries are lightweight, making them easy to carry. The lens tint is also amazing and worth getting. You can take pictures when the sun is not visible, with little or no visible glare. There was no way to go back to a regular camera.
