Yup, I like it too, it's pretty much standard kit lens for my RD1, along with the 28 and 15mm ones. I actually like to use it more than the 50 lux (that I sold) since my Nokton seems to turn smoother than the lux and it doesn't have that pesky focusing knob. Of course, now I am having an affair with the 50/.95 Canon on the RD1, very exciting to see like a cat 🙂
