Scout, the first Lensbaby lens that does not bend, features the Fisheye Optic, which delivers an ultra-wide 12mm focal length capable of capturing a 160 degree angle of view from infinity all the way down to 1/2 inch from the front of the lens. The Fisheye Optic can also create unique flare effects in an image.
“The Scout is for adventurous photographers wanting an easy to use fisheye lens combined with the creative freedom of the Lensbaby Optic Swap System,” said Craig Strong, Lensbaby president and co-founder. “We chose to combine the straight-shooting, non-bending Scout with our 12mm Fisheye Optic so that Lensbaby users could have a simple, affordable, and fun way to play with the Fisheye’s creative flare and eye-opening close focus.”
Due to the extremely wide angle of view of the Fisheye Optic, full frame shooters will generally see a black circle around almost the entire image, and APS-sized sensor shooters will see black at the corners of their images. With Scout, the Fisheye image is always ideally situated in the center of the frame.
The Canon EF 28-135mm f/3.5-5.6 IS USM Lens handles nicely and is easy-to-carry-sized. Size and weight are relative, but most will consider this a small and light lens. A plastic lens barrel helps keep the weight down.
While not built like the L series zooms, the Canon 28-135 lens build quality is decent and in line with Canon’s better consumer zooms. Expect some slight play in the two-part extension of the barrel, expect focus and zoom rings that are not silky-smooth.
The Canon EF 28-135mm f/3.5-5.6 IS USM Lens focuses reasonably fast and very quietly thanks to the Ring USM (Ultrasonic Motor) AF system. FTM (Full Time Manual) focusing is enabled and the manual focus ring does not rotate during AF. The manual focus ring is small/narrow and requires familiarity to quickly find it while shooting. A window provides focus distance information.
While focus is internal, the 28-135 extends like most mid-focal-length zoom lenses in the while zooming until reaching its longest length at 135mm. No focal length lock is present – expect zoom-creep/gravity-zooming when carrying this lens in a downward position.
