Nikon Nikkor 50mm f/1.8 Ai-S - Nikon F Mount

The Nikkor 50mm f/1.8 Ai-S is the successor to the Ai version, distinguished by its shorter 'pancake' or 'semi-pancake' profile, depending on the specific regional version. The Ai-S revision allows for linear aperture control, which is essential for certain Nikon bodies in program and shutter-priority modes. It remains a popular choice for those seeking a compact, high-quality standard lens for travel. Buyers should distinguish between the various iterations of the Ai-S model; some have a closer minimum focus distance than others. SDS checks that the aperture ring moves correctly through the full range and that the glass is clear of scratches. The lightweight construction means it is susceptible to impact damage, so we pay close attention to the filter ring and mount integrity.
