>>4284752not him but yeah, that's the manual ttartisan 25mm ƒ/2.
https://www.ttartisan.com/?list_10/152.htmllooking at ttartisan's site, I didn't know they made a leica summaron-m 28 ƒ/5.6 clone now. too bad it's so expensive and they don't make it for x mount. that would actually be cool. I also didn't know they made a super small 50mm almost pancake now, that's pretty cool.
