Re: Pentax Autofocus Adapter?

[Shaun Canning]

What are you then trying to focus on? If you are attempting to focus on anything closer than 3 feet or thereabouts, the AF adapter will not work properly. If, on the other hand you are focusing from three feet too infinity and the AF doesn't work, it may well be stuffed. I have been trying mine with an SMC-A 50mm f1.4, and it works just fine from infinity down to about 3 feet. Maybe you need to send yours off too Pentax for a service?

Cheers

It depends on the lens in use as well. Make sure it is at least an f4.0 or preferably faster (i.e. f2.8 is great). Also make sure the lens is set to infinity, and that the camera AF is set to single rather than servo focus. It will work on servo, but will easily zoom off somewhere else if the point of focus changes by as little as a couple of millimeters.

It's usually a 50mm f/1.4 and, after getting advice on this list several months ago, I make sure to set it to infinity.
