How to Read MTF Charts

When my article on field curvature was published a while ago, where I talked about how one could do a quick analysis of lens MTF data and determine if it exhibits any field curvature, some of our readers expressed interest in understanding how to read MTF charts. Since we talk quite a bit about lens performance and MTF data here at Photography Life, I decided to write a detailed article on the subject and do my best to thoroughly explain everything related to MTF curves, charts and all the verbiage that comes with them.

Zeiss Distagon T* 35mm f/2.0 ZF.2 Review

Overview

This is an in-depth review of the manual focus Zeiss Distagon T* 35mm f/2.0 ZF.2, a second generation 35mm f/2 prime lens from Zeiss for Nikon and Canon mounts. The lens was kindly provided by B&H – the largest photo reseller in the world that I and many other photographers use to buy photography gear. The lens sample I tested was for the Nikon F mount, although you can get the same lens for the Canon EF mount.

Zeiss Distagon T* 35mm f/2.0 ZF.2

The Zeiss 35mm f/2.0 ZF.2 is a professional-grade fixed wide-angle lens targeted at enthusiasts and professionals that need high quality optics for different types of photography, including landscape, architecture, portrait and astrophotography. Similar to other Zeiss prime lenses, the lens is designed to work on both FX and DX sensor cameras (equivalent of approx 52.5mm on DX) and yields amazing clarity and contrast throughout the frame. The all-metal Zeiss 35mm has a very tough and high quality build and is sealed against dust and tough weather conditions. When compared to the latest generation Nikon AF-S lenses like Nikon 35mm f/1.4G with plastic exterior, it feels much more solid in hands – even the lens hood is made of metal. The focal length of 35mm is a good compromise between ultra-wide angle lenses and standard lenses. Thanks to the 9-blade diaphragm, the Zeiss Distagon 35mm f/2.0 ZF.2 renders background highlights in round, circular shapes, making it a good candidate for portraiture and street photography.
