I haven't had the camera for long, but have done some testing. I've tested it on a running dog to see how the autofocus works. I also took some 4k video to see how that worked. In both cases the autofocus was quick and accurate. The 45mp files have excellent detail and color. I haven't had an opportunity to color grade the 4k footage, so I can't determine final quality.
The camera also handles beautifully. The button layout is intuitive if you've used a Nikon camera in the past. They have moved the most important controls to the right so it's easy to control with one hand. The illuminated buttons are great to have in low light. There are a lot of customizable buttons, making it easy to implement things like back button focus.
In summary, there is a lot to like. Fast, accurate auto-focus, up to 8k video, excellent ergonomics and beautiful output are the highlights.

Excellent buying experience. Camera arrived in excellent packaging. Very responsive to all my questions. Will buy again.

I am an avid Leica M photographer. I was genuinely impressed with the quick and accurate responses to my questions. Prasad was very knowledgeable about Leica, which I greatly appreciate. I would definitely direct my fellow Leica photographers to MF Camera. Excellent service and easy to work with.

My first foray into the Leica world was an excellent experience with MF Camera. Excellent communication, extremely fast shipping, and got a great camera for a great price! MF Camera will be top of my list for future purchases!

Very quick response
Camera is in good condition

Easy to order, fast delivery, no issues with product

I had the Leica Q2. The Leica Q3 added pixels make it even better. Now you can crop from 28mm to 50mm with pixels to spare. The controls and menu are even easier to use. The lens is precise and sharp.

Great communication and delivery.

This is my 8th transaction with this seller and every time it's a flawless transaction. I cannot recommend him highly enough. Buy with complete confidence.

Hi, I received the Leica black chrome Summicron-M 35mm f/2 ASPH. today. Attached it to both my M11 & M10M. Killer! It's exactly what I was looking for. Your posted lens pics and lens descriptions were perfect. And not to forget your quick shipping woohoo. Pleasure to do business with you. Thank you MF Camera! I'll be adding your company to my go to list for Leica lenses & cameras. Until the next time… Best regards, Louis
