great value, they’re unable to offer the same level of optical performance than a more limited-range zoom or a prime lens can, all things being equal. Cor- recting a lens for multiple focal lengths is an engineering challenge, and the greater the range of the lens, the more diffi cult this becomes. Lenses designed Panasonic LUMIX G with multiple optical elements to cor- Vario 14-140mm rect for chromatic aberration and dis- F/3.5-5.6 POWER O.I.S. tortion are necessarily larger, heavier and more costly to produce. While the convenience of all-in-one zooms isn’t without compromise, advances in lens technology continue to improve their performance, and the most common aberrations and distortions are rela- tively easy to address with software.

Current Models Canon offers two extreme zoom lenses, one for their APS-C-sensor cameras and one for full-frame systems. The EF-S 18-200mm ƒ/3.5-5.6 IS for APS-C offers an equivalent range of 29-320mm and image stabilization for up to four stops of correction. For full-frame cameras, the EF 28-300mm Pentax smc DA 18-270mm ƒ/3.5-5.6L IS USM is a premium-quality F/3.5-6.3 ED SDM lens, but that quality comes with added outdoorphotographer.com June 2016 65
