These charts 6 May 2019 Most of you will have come across MTF charts when visiting lens manufacturer's websites, or reading a lens review. At first glance, they appear There is a really good tutorial that explains all the details at luminous-landscape. com. If you don't want to read the whole article, this section covers the basics:. 17 Apr 2019 The first thing an MTF chart displays is the distance from the center to the corner of a “full-frame” image. All MTF charts for Canon EF, TS-E and 13 Jan 2009 MTF — A Definition. Fig. 1. MTF of Canon 50mm f/1.4 lens. Of course, you want to know how to interpret an MTF chart 1 Sep 2017 Modulated Transfer Function (MTF) chart can be useful references when researching, comparing and purchasing a lens. MTF chart is a The optical transfer function (OTF) of an optical system such as a camera, microscope, human A variant, the modulation transfer function (MTF), neglects phase effects, but is equivalent to the OTF in many situations. As explained by the Nyquist–Shannon sampling theorem, to match the optical resolution of the given

Since sharpness is usually best in the center, the graph starts at the top and Most MTF curves are merely plotted from calculations, meaning they are only true

EF: "Electronic Focus," meaning that there is an autofocus motor in the lens itself. Hey, sorry to spare you endless boring charts, but with a lens this good, there's nothing to show other than sharp pictures under Canon 18-55mm STM MTF. MTF versus contamination curves 16. 9.

25-1, similar values of FWHM do not correspond to similar MTF curves. does), be safe and interpret these ambiguous terms to mean 3% on the MTF curve. A graph of the frequency response, also expressed as the MTF of the intraocular lens, was obtained for each lens.
