The Composer Pro II with Edge 35 Optic is a 35mm, f/3.5, tilting lens designed for photographers looking to create unique in-camera shots with a slice of tack-sharp focus and detail, atr a wider focal length.. Tilting this lens, will place a slice of sharp focus through objects in both the foreground and background of an image, bordered by smooth blur. This lens builds on the success of our Composer Pro II with Edge 50 and Edge 80 Optics - but at a wider focal length to fit more of the story into the frame. The Composer Pro II swivels and tilts on a smooth metal ball and socket design, providing a fast and intuitive way to switch between traditional straight lens photos and tilt photography. Keep the lens pointed straight ahead to capture tack sharp 35mm images with no creative effect, or create a slice of focus through the image by simply tilting the lens. Tilt the lens up or down for a horizontal slice of focus; left or right for a vertical slice; diagonally for a diagonal slice. After setting the direction of tilt, rotate the focus ring to move that slice of focus through the image, from one side of the frame to the other. When tilted, the width of the slice of focus depends upon the aperture used. Brighter apertures will produce a thin slice of focus with lots of blur, to isolate the subject from their surroundings, while darker apertures will capture more of the scene in focus. The Composer Pro II is part of Lensbaby’s Optic Swap System, made up of a lens body with an included optic. Simply swap out the optic that it came with, and insert a new optic to completely change the effect and focal length of the lens.
