自己個facebook post條link 想笑人oem貼牌 https://phillipreeve.net/blog/review-syoptic-50mm-1-1
幫你搵埋重點啦:
The Syoptic 50mm 1.1 is one of those lenses and the focus shift is noticeable when making the jump from f/1.4 to f/2.0 and even more noticeable from f/2.0 to f/2.8. For rangefinder users this is rather bad news and definitely something to watch out for.
咁咪即係支鏡本身無撚cal過比rangefinder對焦囉
唔撚識英文又要post英文link

SP 行錯呢步比位人入就一定係柒左
