Book Description
Deciding what lens to buy is complex: What are the ‘pros and cons’ of choosing a zoom lens over a series of single focal length (prime) lenses? Is a long zoom lens a better choice than two shorter zooms? Is it worth paying more for a lens with a wider maximum aperture? Can third-party lenses be a good choice? How about lens adaptors and teleconverters? Lenses Guide outlines some of the technological basics of today’s lenses – the varying mounts and formats, image stabilisation and focusing systems, image sensor size – and their impact on lens performance. It then looks at various categories of lenses: standard kit lenses; telephoto kit lenses; and ‘all-in-one’ extended zoom lenses. This is followed by a series of chapters exploring lenses and different types of photography – landscapes, portraiture, sports and wildlife, and macro photography – along with techniques to improve picture-taking. With lenses at anything from $300 to $3000 and beyond, this guide might be the best lens investment you ever make!

This SPIE Field Guide provides a working reference for practicing physicists, engineers, and scientists for deciphering the nuances of basic lens design.
