All shorts above are hand held, and metering is by trial and error.
Interestingly.... the lower the focal length, the shorter the minimum focusing distance and the higher the magnification factor. I mount the 15mm on the D90, focusing distance is down to 1cm and fired off... And the camera went bonkers! It registered ERR and the mirror refused to come down. I had to mount another CPU coded Nikon lens to resuscitate the camera.
Minimum focusing distance for 50mm focal length is about 23cm. For 25mm is about 10cm.
How about "maximum" focus distance? I don't think they go to ∞.
