The vast majority of my work is done with manual focus. I leave the lens at around 4 or 5 feet on the focus ring and then adjust as I take the shot. It is a very intuitive procedure and most of the time I have confidence in the focus I shot the image at. I have been having some difficulty focusing and it may be that my eyes are at fault. I was born in 1951 and I do wear glasses. I have the most trouble with Voigtlander lenses. The focus ring has lots of resistance and I am late at times acquiring the focus. Now I am having a bit of trouble with the manual focus Nikons. Last week at Glazer’s camera in Seattle, I saw a 50mm 1.8 AF lens. This is a Pre D lens and was made in Japan from 1986-2001. The focus ring is very loose and I wanted to see if it would more effective for my work. It can work on most of my manual Nikon Cameras. The lens costs me $50. Before I could use it on the street I took it on a 2-day trip up Highway 3 to Bremerton and then headed west to Highway 101 back to my home in Olympia. I had the lens on my Nikon FM3a loaded with Ilford Pan F Plus. I developed the film in HC-110(1:31) for 4 minutes @20C.
