Nikon ED AF Nikkor 18-35mm 1:3.5-4.5 D F MOUNTF m

Key Technical Specifications: Angle of View: Offers an ultra-wide angle of view of 100° - 62° on a full-frame camera, ideal for shooting expansive landscapes, large buildings, and interior spaces. Optical Structure: Employs an 8-element, 11-group design, including one ED (Extra-low Dispersion) lens element and one aspherical lens element, hence its "ED" designation, used to suppress chromatic aberration and control distortion. Physical Portability: With a standard 77mm filter diameter and weighing only 370 grams, it is remarkably lightweight and easy to use for a full-frame wide-angle lens. Internal Focusing (IF): The front filter frame does not rotate during focusing, making it very convenient for pairing and adjusting circular polarizing filters (CPL) or graduated neutral density filters. ⚠️ Autofocus (AF) Compatibility Issues: As this lens belongs to the older generation of AF-D lenses, it lacks an internal focusing motor; autofocus relies entirely on the mechanical motor within the camera body. Camera bodies capable of autofocus: All Nikon full-frame (FX format) digital SLRs: such as D610, D750, D780, D810, D850, D700, D3, D4, D5, etc. Mid-to-high-end APS-C (DX format) SLRs: such as D90, D7000, D7100, D7200, D7500, D300, D500. Camera bodies without autofocus (manual focus only): Entry-level APS-C SLRs: D3000 series (such as D3300, D3500) and D5000 series (such as D5300, D5600). Because these bodies lack a built-in motor, when this lens is attached, it can only be switched to MF for manual focus. Nikon Z-series mirrorless cameras: Even if you use the original FTZ or FTZ II adapter, autofocus will be completely impossible because the adapter does not have a built-in mechanical motor to drive the D-type lens. 💡 Misconceptions about using it with APS-C (DX format) cameras: If you plan to use it on a Nikon DX APS-C camera (such as the D7200 or Z50), please be aware that after a 1.5x crop factor, the equivalent focal length of this lens will become 27-52.5mm. It will go from an "ultra-wide-angle landscape lens" to a "normal standard zoom lens with no wide-angle advantage," losing its essence as a wide-angle lens: extremely affordable (currently offering excellent value in the second-hand market); small and lightweight, making it easy to carry while traveling; excellent center sharpness and color reproduction.
