These look pretty cool.
“As of now, photographers with Olympus and Panasonic Micro Four Thirds cameras and Sony NEX-series cameras have the choice to couple a pair of sharp Sigma F2.8 primes to the go-everywhere cameras. These two prime lenses for Micro Four Thirds and Sony E-Mount cameras have been designed from the start for both still and video capture, which, of course, is what makes this camera category so exciting.
The telecentric optical design of these lenses is designed specifically for light transmission to digital sensors for edge to edge image quality, and there’s a new AF system designed for the DN lenses for both still and video capture. On Micro Four Thirds cameras with their 2x lens factor, the 19mm F2.8 EX DN translates to a 38mm F2.8, and the 30mm F2.8 EX DN translates to a 60mm F2.8. On Sony E-Mount NEX cameras with a 1.5x lens factor, the 19mm F2.8 equates to a 28.5mm and the 30mm F2.8 equates to a 45mm F2.8. These are two new serious lenses for a class of cameras that I think are great go-everywhere cameras.”
The Micro 4/3 arena looks pretty interesting, and is something I want to explore more. This kind of gear makes me feel like it is time.
