A full-frame 14mm f/2.8 has been an anchor of Canon's premier L-series lens line for a quarter-century. This new upgrade, Version II ($2,199, street), has a second aspheric element and two elements of ultra-low-dispersion glass. Coatings to suppress reflections from a digital sensor are also new; so are gaskets and seals for better dust and moisture resistance. Equal to a 21mm on a DSLR with an APS-sized sensor, it has a near-fisheye 114-degree angle of view. That width, along with well-controlled distortion, made the previous version popular with architectural and editorial shooters, despite its high price ($2,900) and so-so sharpness (the earlier lens scored an Average rating in our SQF tests -- unusual for such pricey glass).
