One of only two lenses that contains both refractive and diffractive glass elements, this image-stabilized tele zoom is dramatically more compact — and expensive ($1,143, street) — than its refractive-only Canon ($549, street) or Nikon ($479, street) counterparts. Unlike more common refractive optics, diffractive optical design is based on how light rays bend when forced to move around (not through) an obstruction — in this case, a pattern of molded, sawtooth, Fresnel-like, concentric circles. A full-frame lens, it scales up to a 105-450mm on Canon EOS Digital Rebel models.
An 88-400mm equivalent, this is Canon’s longest EF-S (digital only) zoom, and roughly the low-cost digital alternative to its 100-400mm f/4.5-5.6L full-frame “white” image-stabilized zoom that’s so hot with pros. At $280, street, this 55-250mm is by far Canon’s most favorably priced IS tele zoom, with the only glass close to it a 70-300mm IS lens that streets for roughly $550.
Not actually paired in a kit with Canon’s 18-55mm f/3.5-5.6 IS starter lens (yet), this is the system’s de facto kit telezoom. It’s squarely targeted at intermediate DSLR shooters who feel hemmed in by the 18-55mm and crave something longer. While most comparable digital tele-zooms that start at 55mm go to only 200mm (i.e., the Nikon, Sigma, and Tamron), Canon reaches out to 250mm.
If you needed proof that Pentax has a high-performance, professional-quality DSLR in the offing, this $1,000 (street) lens is it.
Based on the film-era 200mm f/2.8 FA lens, it’s equipped with new internal-flare-suppressing coatings, and it has a newly designed rear element which Pentax claims projects a perfectly flat-field image. A 300mm equivalent, it sports Pentax’s SMC supersonic focusing motor for near-silent autofocus action, as well as Quick-shift focusing that lets you touch up focus manually while the lens remains in the AF mode.
This digital-only, 5.3X, wide-to-medium-tele, general-purpose zoom ($600, street) is an attractive upgrade for Nikon shooters underserved by their entry-level 18-55mm kit lens. No longer a beginner? It offers Vibration Reduction, plus extra reach in both directions, scaling up to 24-127.5mm on most Nikon DSLR bodies. Two extra-low dispersion glass elements rein in the image-softening effect of chromatic aberration (a.k.a. color fringing), and three aspheric elements help tackle linear distortion.
