Originally posted by D1N0 Mine turns out only to be focussing up to 9 meters so something is wrong with it. The rear element seems to deep. When I focus to mfd there is a gap between the rear element and the tube it slides through. Could you check if yours does that?
I have had great shots at all focus distances from minimum (under 5 feet) to infinity. I see no gaps anywhere - everything fits and slides snug as can be. At minimum focus distance the rear element is about two inches in from the mount ring. Mine is a PK mount, I guess your Pana is the same.

I've been keeping my eyes peeled for a 40mm f/1.8 after letting one slip through my fingers for little money...
On an aside, you'll love the Tak 135/3.5. I got one of my favourite pictures of Mabel out of an SMC variant of the 135mm f/3.5.
I couldn't tell if the mount was Konica AR or M42, the adapter was a generic with very little written on it, the lens was shown only with the adapter mounted. I can use the 24mm on my Sony in full frame mode, so it's a good buy for that purpose. I will know in a day or two when the postman arrives, and then I can tell you.
I bought the Tak because I have been disappointed with the sharpness of my Pentax M 135/f3.5, and I want a small 135 for travelling. I have the larger Adaptall2, Vivitar (Komine) and Jupiter 37A for driving trips.
