Sony’s New Zoom Lenses for the PMW-F3 | CineTechnica

Sony’s New Zoom Lenses for the PMW-F3 | CineTechnica | FOTOGRAFIA Y VIDEO HDSLR PHOTOGRAPHY & VIDEO | Scoop.it
Sony has just announced details on their upcoming zoom lenses for the F3. The new SCL-Z18X140 lens is a 14x powered zoom in the native Sony F3 mount. It will ship in November with a list price of $12,200, but will likely retail for less. This zoom is the first servo driven lens designed to cover the Super-35 sensor found in the F3. It features full auto iris, auto focus and stabilization. At the wide end of the lens, it has an aperture of T3.9, which drops to around T6.8 at the end. However, the image stabilization and other functions add up to make it quite an amazing lens. Firmware version 1.20, which enables the use of the zoom rocker found on the side of the camera, is required to use the lens. The firmware will also be released in November; see yesterday’s blog for details. View the bottom of the post to see the full specs of the new lens.

The widest optics in terms of field coverage are fisheyes, which can display up to 180° of whatever lies before your camera. Fisheyes come in two varieties—circular, in which the scene is rendered as a sphere, and full field, in which the full 180° image field is displayed across the entire image frame. Although fisheye images are inherently chock-full of linear distortions, there are a number of OEM and third-party software applications that can correct a large number of these distortions at the cost of a few degrees of the image’s original field coverage.
