The photographic Lenses: Management, Technique and Control.

By Ernesto Martínez

A lens isn't just a set of lenses encased in a cylinder of metal and glass. It's a promise. A way of seeing. A decision about what to include and what to leave out. Each lens is a different voice that translates light into language, that transforms the world into image. This book is not a catalog of specifications. It is a cartography of possibilities. Here you will not only learn what a 50mm does or how a stabilized zoom works. Here, you'll find out how the narrative changes when you switch lenses. How a wide-angle lens breathes spaciousness, how a telephoto lens whispers intimacy, how a macro reveals the invisible. This book is for you, who want to choose with awareness. That you know that each lens is a tool, but also a metaphor. That you understand that technique is not separate from emotion, and that every optical decision is also a poetic decision. In this volume number 8 of the series "HIGHER EDUCATION IN PHOTOGRAPHY" we approach the universe of photographic lenses from a comprehensive perspective: technical, functional, narrative and emotional. Throughout its chapters, the reader will find clear explanations, practical comparisons and in-depth reflections on the following key elements: 1. Optical and Physical Construction - Internal elements: spherical lenses, aspherical lenses, ED, UD, anti-reflective coatings. - Optical groups: arrangement and function of each set of lenses. - Body materials: metal, polycarbonate, sealed against dust and moisture. - Mount: type, diameter, registration distance, compatibility. 2. Essential Technical Parameters - Focal length: how it affects the angle of view and spatial compression. - Maximum aperture: f/ ratio and its impact on light, depth of field and bokeh. - Minimal focus and magnification: determinants in macro and detail. - Optical stabilization: motion compensation in lenses with IS, VR, OSS, OIS. 3. Functional typologies - Standard lenses: versatile, natural, balanced. - Wide angle: for landscape, architecture, interiors. - Telephoto lenses: for portrait, wildlife, sports. - Macro: for extreme detail and 1:1 playback. - Specials: fisheye, tilt-shift, pancake, cinema. 4. Ecosystems and compatibilities - Reflex and mirrorless mounts: EF, F, E, RF, Z, X, L, MFT, GFX. - Adapters: electronic, mechanical, with or without loss of functions. - Support for APS-C and Full Frame bodies. - Third-party lenses: Sigma, Tamron, Tokina, Samyang, Laowa, TTArtisan. 5. Optical Performance and Testing - Sharpness: center vs. edges, effective resolution. - Aberrations: chromatic, spherical, coma, distortion. - Vignetting, flare, ghosting: how they affect the final image. - MTF curves: interpretation and comparison between models. 6. Conscious choice and creative use - How to choose according to photographic genre, style and workflow. - Relationship between focal and visual narrative. - Practical exercises to explore each type of lens. 7. Maintenance and longevity - Cleaning of optical elements. - Field protection: filters, sun visors, cases. - Diagnosis of optical problems. - Useful life, repair and resale value. This book is designed for photographers in training, professionals in search of specialization, and visual creators who want to understand optical language in depth. Each chapter can be read independently or as part of a progressive walkthrough. The intention is clear: that each photographer chooses their lenses with knowledge, with emotion and with purpose. Welcome to this tour. May each page bring you closer to your gaze. That each lens teaches you to see differently. Let every choice be an act of intention.
