I was just wondering, if I'm getting some old cheap MF-lense for my Nikon D50, will I still be able to utilize the AF-sensors? I've noticed that on manual focus I still see that little "dot" in the viewfinder once the subject in the selected AF-measurefield is sharp. From a technical view there shouldn't be much of a problem with it, so I'm wondering if anyone every tried it and if it's perhaps disabled in the firmware. I could live with the loss of the light meter when using MF (wouldn't shoot "time-critical" stuff with it anyway) but the focus help would be invaluable as it's difficult to check out right where I'm shooting. Thanks your your replies.
