Ten years after the publication of Infrared Optics and Zoom Lenses, this text is still the only current publication devoted exclusively to infrared zoom lenses. This updated second edition includes 18 new refractive and reflective infrared zoom systems, bringing the total number of infrared zoom optical systems to 41 systems. Other additions include a section on focal plane arrays and a new closing chapter specifically devoted to applications of infrared zoom lenses. Coverage of wavelength region has been expanded to include the near infrared. Additional topics include an examination of the importance of principal planes, methods for athermalization by means of computer glass substitution, and global optimization techniques for zoom lens design.

A concise introduction to lens design, including the fundamental theory, concepts, methods and tools used in the field. Covering all the essential concepts and providing suggestions for further reading at the end of each chapter, this book is an essential resource for graduate students working in optics and photonics.

46 Canon EF Lenses are introduced to meet your photographic enthusiasm! Learn from the many shooting techniques to fully exploit the ability of your lens. Also, practical samples of lens combinations according to your favorite shooting scenes.

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!
