D200 focus problem and katz eye focus screen

[carlosquandt]

Hello

 

Please, first of all excuse my bad english

 

Im using now a new Katz Eye focus screen with no prisms and the problem is the

autofocus does not work very fine. It focus on the object but not precisely.

And the problem persist even changing the focus area

 

So, does anybody know what happens? Could it be problem of the focus screen (a

non nikon one)? I have been using another katz eye focus screen without problems

 

Thanks in advance, Carlos

Are you sure it's put in correctly? If it's not perfectly in place it could cause problems.

To my knowledge the focusing sensor in the D200 (and any other Nikon AF Camera other than the first F3AF) lies in the bottom of the camera, so your new focusing screen should not interfere with AF. I bet you did not set the screen properly or maybe upside-down so that the camera focuses correctly but what you see in the finder is out of focus. Goold luck, Marco

Marco is correct. The focusing screen has zero influence on the autofocus system. Chances are pretty good that you have not installed the Katz-Eye screen correctly.

 

Good luck.

Or you have bumped the diopter setting.
