Nikon Nikkor-Q Auto 200mm f/4 - Nikon F Mount

The Nikkor-Q Auto 200mm f/4 is a vintage telephoto prime lens known for its solid mechanical build and classic rendering. As a 'Q' (Quattuor) designated lens, it features a four-element optical design. This model is a Pre-AI lens, meaning it requires modification for use on many modern Nikon DSLRs, though it remains a popular choice for adapting to mirrorless cameras where its long focus throw allows for precise manual adjustments. When inspecting this lens, pay close attention to the condition of the aperture blades, as older Nikon primes can occasionally suffer from oil migration. The focus helicoid should be smooth and even across the entire range; a stiff or gritty feel usually indicates dried lubricant. We check the integrated telescopic lens hood for dents that might prevent it from sliding freely and ensure the optics are clear of age-related blooming or fungus.
