Today I share more street photography photos taken with the Sigma sd Quattro, the ability to compose and capture 21:9 aspect photos in-camera is magical; I almost feel like I'm taking snaps from a motion picture :)
The raw files from the camera are around 50 MBs, and when I convert them to 16-bit TIFFs the files sizes are larger at around 70 MBs. The aspect ratio can be changed after the fact if captured in raw. For editing I usually import and edit the TIFFs in Lightroom.
SUPER cool. I didn't even realize it had that capability. That's like digital X-Pan. They look amazing.
