As a professional photographer I'm very impressed with this mirrorless camera. I mainly got this to have another 4K camera I can use for vlogging and and extra setup but the photo quality is impressive as well. Cool thing about this little camera is that it can constantly be updated like a phone so it's like your having a new camera every time with new features. Great buy in my opinion.

Yes, the YI M1 is a cheaply made, plastic bodied Micro 4/3 mirrorless camera with "Baby Leica" styling aspirations, and yes, its nearly all plastic lenses are far from the sharpest around. No, it's not reliable as a video camera, either; the M1 lacks both manual control for setting video exposure and a microphone input jack for better sound recording. It's a quirky little camera which, although designed for and marketed to total amateurs and casual enthusiasts stepping up to an ILC from their smartphones, actually requires advanced photographic techniques in order to get top notch results from it. The juicy 20MP Sony sensor is the YI M1's best selling point - colors render nicely, and with a good pop to them. However, with even its highest quality level JPEGs rendering slightly soft and mushy, the YI M1 fortunately delivers very good RAW files when set to "Manual" mode and low ISO settings are used. Better quality lenses also help enormously - I've purchased two used Panasonic zooms, with the 12-60mm providing the best results so far. I like the easy to use swiping interface - it works relatively well, for the most part, with only occasional lagging when selecting shutter speed and aperture settings, plus deleting files. Using the touch screen with its multiple focus points provides the fastest means of focusing an image - it also can trigger the shutter. Bottom line: Despite its numerous tics, the YI M1 provides a compact, capable option for taking above-average RAW file images (with the average size coming up to 31MB). After learning the camera's limitations and keeping it set to RAW mode, I've come to really enjoy using mine - it reminds me of shooting film. So, if anybody is curious enough to try one, be certain to get a good copy (the first I bought was defective in setting exposure options, the second has been the charm), buy some better glass for it, use touch point focusing, keep ISO settings to 400 tops, forget using the video for more than quick little clips (until the long promised third software upgrade finally is released, that is), purchase a couple extra batteries, and the YI M1's charms just might reveal themselves. It won't be the best camera anyone has ever used, but it can be a lot of fun in its own right.

I still haven't explored this camera to it's full potential. However, what I have seen so far, I'm liking it. It's better than a point and shoot, it has many more features, and the fact that it's compatible with my newer flash, makes it ideal for shots requiring flash.

If you shipped any faster the camera would have been here before I ordered it. The camera....I have only played with it so far, learning about it, and I am impressed. I've read some reviews that are critical of the camera from those who use $3,000 + mirrorless cameras and they pick at some rather trivial points, but for $2,700 less I'll enjoy my YI M1 4K a lot. I am impressed with its quality, its' compactness and the many features it does have. Very clean design and one that stops you is the lack of controls and knobs. It's all on the touch screen, and I love it!
So I can't impress anyone with how much I spent but I am impressed with what I see, including the pictures I have taken easily with the camera.

I am using this camera for almost two days. Even though this Camera takes excellent pictures inside, outside & low light but I am having trouble with auto focus when taking pictures other than automatic mode. Camera ruined my many shots during Manual & Master Guide mode due to focus issue and resulted in a blurry picture. I am not having focus issue in automatic mode. I hope a future update will fix this issue.
