BEFORE USING THE LENS (Read the following carefully and get the most out of your new lens now and in the many years to come.) You now own one of the brightest, easiest-to-focus telephoto lenses for close-up photography-the Micro-Nikkor 105mm f/2.8. And now it's all yours: beautiful close-up shots of the hardest-to-capture subjects/ from shy butterflies to wriggling reptiles, taken from a safe distance without disturbing your subjects . . . or endangering yourself; captivating portraits; and fascinating photos shot when lighting is less than perfect. With the Micro-Nikkor 105mm, viewfinder image is bright and clear, even in dim illumination. You can focus easily . . . and see the difference in your photography immediately. Even with its long focal length, the Micro-Nikkor 105mm stands out as compact and easy to handle. That's because its special optical construction means only a slight increase in lens extension, even when you're focusing at close distances. And of course Nikon has assured good performance from infinity down to the closest focusing distance (0.41m, 1.34ft) with a 1:2 reproduction ratio, even at full aperture, with its Close-Range Correction System. With NIC (Nikon Integrated Coating) applied to the air-to-glass surfaces of the lens element, not only do you avoid ghost images and flare, but color rendition is also improved. And with suitably equipped Nikon cameras, this lens offers "Automatic Maximum Aperture Indexing" (AI), permitting full aperture exposure measurement through the dual functioning of the meter coupling ridge and automatic diaphragm. You can get the same operation with non-AI type Nikon cameras by using the lens' metering coupling shoe. For further focusing extension from 1:2, just attach the Auto Extension Ring PN-11, a Teleconvertor or a bellows attachment. 5
