I want to locate an adapter without any optical lens that can enable me to use minolta md lens in DSLR cameras, with focus to infinity.
SOURCE: how do I use the
well is it a analogue lens designed for 35mm film camera's of minolta ? Most of the time wenn using a non -cpu lens on a dslr body yuo have to lock the apature to the highest count (for example F 22 ) otherwhise thae camera will or might refuse to operate. if the lens is not to old you can try if the camera will outo focus if not you have to set the Autofocus to Manual Focus and lock on the target by turning the focus ring

SOURCE: nikon 18-200 mm vr lens not auto focusing on my nikon d200
lets start with the basics, try hard reseting it and try again, if that doesnt work then
try upgrading your firmware (if possible on your camera) and if that doesnt work then it may be the lens, but dont forget to spend a few hours trying to find a option for it in the meny
SOURCE: My DSLR shows a vignette in photos when the lens is extended
My guess is that it is a bad lens or an inexpensive lens. If it is a zoom, does the vignette become worse as you zoom in? If yes, it's the lens.
SOURCE: The lens kit of my Sony DSLR A200 produces noise
If it's in continuous auto-focus and doing it, then it is just not locking on to one thing and jumping back and forth between two objects that are very close together in distance and it is normal. It should stop in manual, single shot or single point auto-focus. Sony uses Nikon auto-focus technology and my D-300 with a 70-200mmf2.8 will do it if I turn the auto-focus tracking time(lock-on) all the way down with the auto-focus in full auto.
