En	Nikon offers a variety of interchangeable focusing

	lens or picture-taking situation. Those recommended
	for your teleconverter/lens combination are listed on
	pages 144–145.
	T= Excellent focusing
	R= Acceptable focusing
	Slight vignetting or moire phenomenon affects
	screen image, but film image shows no traces of
	this.
	Y= Acceptable focusing
	Split-image rangefinder, microprism or cross-hair
	area is dim; focus on the surrounding matte area.
	[= Indicates degree of exposure compensation
	required in Center-Weighted metering. See User's
	Manual of the camera body for more details.
	fF= Exposure measurement not possible;
	teleconverter/screen combination permits only
	focusing operation.
	Blank box means not applicable. Since type M screen
	can be used for both macro photography at a 1:1
	magnification ratio or higher and for
	photomicrography, it has different applications than
	other screens.

■Attaching to the lens

When removing the lens from the camera body to attach the teleconverter, make sure that the camera's power is turned off and avoid direct sunlight.

To attach

Attach the teleconverter to the lens so that the teleconverter's lens mounting index is aligned with the aperture index on the lens. Taking care not to press the lens release lever, turn the teleconverter counterclockwise (with the lens facing away from you) until it clicks into place.

To remove

Slide back the teleconverter's lens release lever and turn the teleconverter clockwise (with the lens facing away from you) until the teleconverter's lens mounting index is aligned with the lens' mounting index.
