I did not know that. You are saying that aligning the split image in my SLR prism is somehow less accurate than aligning the images in a rangefinder because of the acuity of my eyesight? Somehow that does not really make sense to me. In both cases my eyesight is involved. I should be able to align to blurry halves of an image in my SLR viewfinder as well, or not as well as the case may be, as I can two blurry ghost images in a rangefinder spot. Hmmm.
