Overview and Price in Pakistan
The Nikon 105mm f/2.5 Ai lens is an iconic telephoto lens known for its robust build quality and all-metal construction typical of Nikon’s Ai lenses, complete with colorful aperture stops, an engraved depth-of-field scale, and smooth, resistant focus and aperture rings. Originally produced in the 1970s, it was favored by photojournalists for its portability, durability, and impressive optical performance, notably used by Steve McCurry for his famous “Afghan Girl” photo.
Key Features
- Build Quality: All-metal body, engraved markings, durable construction.
- Optics: Low vignetting, especially notable after f/5.6; minimal chromatic aberration at mid apertures.
- Sharpness: Strong at portrait distances, peak performance from f/5.6 to f/8, though slightly softer wide open.
- Bokeh and Coma: Pleasing, unobtrusive bokeh with well-corrected coma, making it suitable for portraiture.
- Flare and Distortion: Moderate flare resistance due to its age; nearly no field-relevant distortion.
- Aperture Control: Full-stop click stops with a slight overrun past f/2.5.
Performance on Modern Cameras
When used on high-resolution digital bodies like the Sony A7rII, the Nikon 105mm f/2.5 performs respectably, though it benefits from stopping down slightly to f/5.6 for optimal sharpness. Some minor focus shift and chromatic aberrations may appear, but these are manageable and mostly correctable in post-processing.
Conclusion
The Nikon 105mm f/2.5 Ai remains a reliable, compact lens ideal for portraits and reportage. It may lack some modern enhancements, but its combination of quality bokeh, low vignetting, and portability make it a valuable vintage option.
