You need to get the goggles to be working properly with your m9 (infinity point must be aligned between lens barrel focusing point ans VF image (strangedly, my M9 did not,...but my M8 did. All my other non goggle ASPH lenses worked well with both m8 & M9).
I needed the magnifier 1,4x (for m8, cause the frame is a 120mm framelines box size compared to m9's 90mm framelines due to crop factor of 1.33) for utilizing the f2.8 as I noticed the razor thin DOF easily lost my focused subject but rather focused onto objects near to the focused object at close distance.
hmm, interesting that we are seeing similar issues here. I focused mine at infinity and it shows up as being focused in the viewfinder, and then i shoot a building that's at least 1 km away, and the image is still horribly blurry. not sure what the problem is though. It's a great little lens, really hope to be able to get this fixed
