![]() ![]() But you can use MTF charts as a scale to measure lens performance. This Nikon 35mm f/1.8G lens is a compact, lightweight, fast normal to wide-angle lens for full-frame FX and 35mm cameras. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. Performance characteristics of photographic lenses cannot be expressed with only MTF charts. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance. AF-S DX NIKKOR 35mm f/1.8G Nikon ImagingUSAAmericas Nikon Global Cameras Lenses Sport Optics Software Other Deals Education NPS Support News AF-S DX NIKKOR 35mm f/1.8G 199. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. Nearly as versatile as a prime lens can be, the AF-S DX NIKKOR 35mm f/1.8G from Nikon is a 52.5mm-equivalent lens for DX-format cameras, and is characterized by. Lens performance differs depending upon directions. Lastly, the Sigma 35mm f/1.4 Art is optically the most complex it has a total of 13 elements in 11 groups, 2 of which are aspherical and 5 of which are. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be. The Nikon 35mm f/1.4G has the oldest optical design in the group, with 10 elements in 7 groups, rounded 9-blade diaphragm, a single aspherical lens element and contains Nano Crystal coat. That’s pretty near a macro capability for a wide angle lens. Nikon 35mm f/1.8G AF-S DX Nikkor 35mm wide aperture lens with high-quality optics and compact dimensions designed for use with Nikon DX format cameras. For what it’s worth, the Tamron focuses closer: 8 (.2m) compared to the Nikkor’s 10 (.25m), netting a 1:2.5 maximum magnification ratio. The Tamron is larger physically and heavier by nearly 50. The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. That compares to 2.8, 2.8, and 305g for the Nikkor 35mm f/1.8. Grab the focus ring at any time for instant manual-focus override. ![]() It has great optics and ergonomics in a lightweight housing. MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures. This Nikon 35mm f/1.8G lens is a compact, lightweight, fast normal to wide-angle lens for full-frame FX and 35mm cameras. 22.22 wider aperture at minimum focal length f/1.4 vsf/1.8 Has a metal mount Weather-sealed (splashproof) 0.4f wider aperture at maximum focal length. ![]()
