The Spring Lens Scene: Ingenious Innovations in the Glass Class

The Spring Lens Scene: Ingenious Innovations in the Glass Class


While the imaging world has been transfixed by awesome developments in sensor and image-processing technology, the 4K video revolution and advances in on-sensor phase-detection AF, an equally impressive transformation has been taking place on the optical front.

In the past two years, literally hundreds of interchangeable lenses were introduced, spanning every format from compact system cameras, APS-C and full-frame DSLRs and digital medium format. This optical explosion not only enhances the range of creative opportunities for picture takers, from casual shooters to pros, it also expands your profit potential.

In analyzing the latest entries, several trends emerge. As shooters become more sophisticated, creative expression and the esthetic quality of the image have come to the fore, and this has resulted in a renewed interest in wide-aperture prime (single focal length) lenses that create beautiful bokeh effects using limited depth of field at apertures in the f/1.2–2.8 range. Virtually every major lens manufacturer has jumped into the fray and offers an enticing assortment of high-speed primes covering all formats.

At the other end of the spectrum, zoom ranges are steadily increasing, and there are several new ultra-long telephoto zooms as well as long-range, wide-to-telephoto zooms that are wider at the wide end and provide unprecedented overall zoom ranges. Other notable lens trends are: flat, ultracompact wide angles and wide-angle zooms; high-performance lenses, often at premium prices; lenses with built-in, ultraquiet stepping motors for shooting video without focusing noise; and creative lens accessories that let shooters put the zone of sharpness where they want it.

Perhaps the greatest thing about lenses is they’re “keepers” that migrate to the next, more advanced camera body as customers upgrade to take advantage of the latest technology. As a result, lenses have a higher resale value than cameras and a higher perceived value among consumers. Indeed, lenses are considered long-term investments that will pay dividends going forward, and that’s one reason the optical sector is one of the healthiest, most dependable niches in the digital marketplace.
