Voigtländer Trio Review: FE 10mm, 12mm, and 15mm Extreme Wide Angle Lenses
by E.J. Peiker | May 03, 2017
In October 2015, Austrian iconic specialty lens brand Voigtländer, now a division of Cosina, the same company that manufactures most Carl Zeiss camera lenses, announced that they would be bringing a line of ultra-wide angle lenses to the Sony full frame E-mount platform by Spring 2016. The announcement was for a redesigned version of the Leica M-mount 15mm ƒ/4.5 and 12mm ƒ/5.6, and a brand new design of a 10mm ƒ/5.6. The actual names of the lenses are as follows: Continue reading »
Bird Species Spotlight: Brown Pelican
by Jake Jacoby | May 02, 2017
Squadrons of brown pelicans can routinely be seen flying together in v-shaped formation above the surf line along both the southern and western coasts of the United States. While there are seven species of pelicans, the brown pelican is the smallest and the only one that plunges from the air into the water to catch its food. They feed by plunge-diving from high up, using the force of impact to stun small fish before scooping them up. While the brown pelican is draining the water from its bill after a dive, gulls often try to steal the fish right out of its pouch. They sometimes even perch on the pelican’s head or back and reach in. The pelican itself, however, is not above stealing fish from other seabirds. It also follows fishing boats and hangs around piers for handouts. Continue reading »
Sigma 500mm f/4 DG OS HSM Sport Lens Review
by E.J. Peiker | April 11, 2017
The Japanese lens manufacturer Sigma has been around since 1961 and for much of its history it has been known as a company that makes budget lenses for Nikon and Canon cameras (and others at times). In late 2012, Sigma went public with a desire to no longer be seen only as a budget third party lens maker. They came up with the Global Vision line of lenses, new state of the art manufacturing processes and a vastly upgraded quality control process. The Global Vision lenses are part of three different distinct product lines. The Contemporary line stays true to the original Sigma concept—consumer grade lenses made of lighter materials at prices significantly below the camera manufacturer’s lenses. The Art line of lenses was conceived to make the finest prime and short zoom lenses, lenses that meet or exceed the very best that the OEM’s and even specialty lens companies make regardless of cost. And finally a Sport telephoto line that makes high end long lenses equal in performance to what the likes of Canon and Nikon make. These three lines have become unmitigated success stories and have moved Sigma from the realm of cheap knock-off lens maker to an innovative high end lens maker that produces lenses as good or better than anything on the market. Art lenses are even on par with specialty lens makers like Zeiss and often exceed the image quality of similar Canon and Nikon lenses. As an example, their latest 85mm is considered an equal to the ultra high end Zeiss 85mm Otus lens at a drastically lower cost, and it has autofocus which the Zeiss does not. Continue reading »
