Head-2-Head Micro 4/3 Kit Lens Review: Panasonic Lumix G Vario 14-45mm vs. Olympus M.Zuiko Digital ED 14-42mm
on Sep 22, 2010 at 9:00AM

The Micro Four Thirds system gleams some much-deserved attention within the digital interchangeable lens arena, again painting Panasonic and Olympus as innovators with their assortment of diminutive, mirror-less digital cameras. 
Panasonic and Olympus both make kit lenses for the Micro Four Thirds standard that bear the stylization and design choices germane to each manufacturer....

Head-2-Head Micro 4/3 Lens Review: Olympus Zuiko Digital ED 7-14mm f4 vs. Panasonic Lumix G Vario 7-14mm f4
on May 17, 2010 at 12:00AM

Olympus and Panasonic engineer quality lenses for Four Thirds and Micro Four Thirds formats that match or surpass those available for APS and full-frame DSLRs. Both companies offer 7-14mm zooms that correspond to a 14-28mm lens on the 35mm format with an angle of view of 114-degrees. The fundamental difference between the Olympus 7-14mm and the Panasonic 7-14mm is that the Olympus has a standard Four Thirds mount and the Panasonic has a Micro Four Thirds mount....

Head-2-Head Lens Review: Canon EF 85mm f/1.2L II USM vs. Canon EF 85mm f/1.8 USM
on Apr 6, 2010 at 9:57AM

These two lenses represent a fairly classic "battle for speed" between two optics from a single manufacturer. The Canon EF 85mm f/1.8 USM lens sells for an MSRP of $419.95, and is a standard short-telephoto Canon workhorse. Canon's more exotic 85mm prime, the EF 85mm f/1.2L II USM, buys you an additional stop of exposure latitude, superior build quality, extremely high resolution, and what is described as a "silky-smooth" bokeh effect. Sporting an MSRP of $2199.95, and nearly twice the size and weight of the EF f/1.8, we evaluate whether Canon's "L-Series" glass warrants the near $1,800 upgrade....

Head-2-Head Lens Review: Canon EF 16-35mm f/2.8L II USM vs. Canon EF 17-40mm f/4L USM
on Mar 5, 2010 at 7:01AM

Canon's EF 16-35mm f/2.8L II USM ($1699 MSRP) and EF 17-40mm f/4L USM ($839.99 MSRP) are two of the most popular "Ultra-Wide Zoom" lenses available for its mid- and upper-level DSLRs. The 16-35mm f/2.8 II is an update of the previous 16-35mm f/2.8 lens, and is said by Canon to offer a complete optical redesign for increased resolution and contrast. The 17-40mm f/4 is billed as a high-quality, budget-priced "L" lens by Canon, at a stop slower than the 16-35mm f/2.8 II and just a bit more than half the price. The question is, how do these lenses stack up optically?...
