Yi Mirrorless Camera Manual

I have a YI mirrorless camera. I wanted to attach it to a telescope for astronomy pictures. This fit the camera and the telescope barlow lens perfectly.

As its label (50mm f/0.95) would suggest, this lens is an extraordinary photographic tool, either on an M-mount (Leica) camera or, with various adapters, on mirrorless cameras (albeit with manual aperture & manual focus). There's no issue with focusing accuracy with a mirrorless camera, of course, but with an M-mount camera the maximum aperture (f/0.95) accurate focusing may require an adjustment to the lens to work precisely with the camera's rangefinder, and TTArtisan kindly provides the tools and instructions for doing that. My copy of this lens, however, was perfectly adjusted right out of the box (whether that's the exception or the rule, I cannot say). This lens used good materials (metal) and is well put together---a quality product. Is this lens a paragon of optical perfection? No, far from it, but you don't buy an f/0.95 lens for that; you buy it for the unique effects you can obtain at maximum aperture. Is it a world-beating built-like-a-tank masterpiece of optical and mechanical construction like the Leica 50mm Noctilux? No, of course not, but it also costs only about 6% of the price of a Noctilux ($755 vs. $12,795), which makes it an extraordinary value for the money.

If you have old -now called V system- Hasselblad/Zeiss lenses around this little gadget will allow you to use them on your mirrorless camera. You will have to use manual focus and there won't be any stabilization but other than that, they will work well.

juss brought a yi 4k action camera and needed this particular memory card for it, allows me to shoot ton of pics and vids with all the memory it contains. perfect fit

All I ever wanted in a Mirrorless Camera.

Great mirrorless, manual lens. Contrasty, beautifully rendered photos come from this. Buy it.

very useful, found out things about the camera the manual does not show.

Great product. I think one of the best mirrorless camera out there.

I use it for my mirrorless camera. Would recommend.

The best camera so far, love the mirrorless tech.
