Latest Review Posted Yashinon DS-M 50mm f1.4
While I also have many other manual lenses of this focal length, I find that with this lens, it is easier to lock-in focus using my k-5. I have a feeling that the coating from this lens is a better than most others may have something to do with that. The coating on this lens is between the earlier version from Tomioka (more yellowish) and the later version (more blueish). As mentioned, the only gripe that I have is missing the A/M switch. However, I managed to alter the aperture control mechanism to a full-time manual mode by putting a spacer between the pin and spring lever inside the lens. I will upload some photos later when I have a chance.
