Nippon Kogaku 135mm f3.5 Nikkor-Q eye piece Just regular stuff you canThe Nippon Kogaku 135mm f3. 5 Nikkor Q Auto is a good quality short telephoto lens for the Nikon F mount. This is an older version of this lens (hence the Nippon Kogaku branding) but the optics are clear, mechanical function is good, and image quailty is solid. Note that this is a pre AI F mount lens, so compatibility may be limited with modern cameras (but it works great on most adapters)
