Is it possible to fine tune the green dot indicator on a manual focus lens ?
I'm guessing the lens needs to be chipped so at least the camera knows what lens is mounted ... ? other than manually tagging it in the manual lens menu
I have a 50mm f1.8, if I use the green dot for focus confirmation the focus is in the ball park and ok for web images ,
I get better results by observing the image get in and out of focus and settling for a middle point
all of these while using the lens wide open, smaller apertures are easier to handle
