The Edge 35 is part of Lensbaby’s Optic Swap System and is designed to be used with the company’s Composer Pro or the newer Composer Pro II lens housing, which is also available as a kit with the Edge 35 Optic.
For those unfamiliar, Lensbaby Optics are not lenses in their own right, but add-ons for the Lensbaby Composer Pro housing; this is available for the Canon EF, Canon RF, Nikon F, Nikon Z, Fujifilm X, Micro Four Thirds, Sony E, Sony A, and Pentax K mount - plus for the L Mount used on full-frame Panasonic, Leica, and Sigma mirrorless cameras.
An Edge Optic creates a slice of focus in the image, within which everything will be sharp, while everything else can be rendered increasingly or decreasingly blurry. The very first Edge Optic was released in 2012, the Edge 80, with the 50 following in 2016 – which had focal lengths of 80mm and 50mm respectively. Lensbaby tells us that a 35mm version was the most requested lens that it has ever made, so anticipation is high for this release.
The Edge 35 doesn't disappoint. Offering a 35mm focal length with an f/2.5 aperture, the lens is extremely sharp edge-to-edge with a flat field of focus that performs like any well-corrected lens.

As the Composer Pro II doesn’t have any electrical contacts, the first step is to open the camera menu to set it to shoot without a lens. Most cameras will meter correctly in aperture priority mode, but you can also use manual if you prefer.
Once the Edge 35, is mounted in the Composer Pro II, the housing’s ball and socket design allows the optic to be tilted in any direction. This moves the plane of focus in the image like a regular (but expensive) tilt-and-shift lens (although there’s no capacity to shift), enabling you to create a sharp band across the scene with near and far objects both being in focus. Tilting up or down creates a horizontal slice of focus while tilting left or right gives a vertical slice, and tilting diagonally produces diagonal slices. A locking ring near the lens mount enables the movement to be tightened and loosened as required.
The build of the Edge 35 is streets ahead of that of Lensbaby’s original bendy lenses. The barrel is metal and the elements are glass, so it has a nice weight to it and feels like a good-quality optic. Much of the barrel of the optic is taken up by the aperture ring which has settings running from f/3.5 to f/22. Focusing, which is manual only, is performed using the front ring on the Composer Pro housing.
It’s useful to activate the focus peaking and to customize a button to activate the magnified view as this helps you get the focus just where you want it. With careful focusing, you can get impressively sharp results at the point of focus, with steep fall-off and attractive bokeh.
It works identically to the other Edge Optics; paired with the Lensbaby Composer Pro II you get nearly 15 degrees of tilt, which is nearly twice as much as most tilt-shift lenses. If you tilt up or down you get a horizontal slice of focus running through your image, while tilting left or right creates a vertical slice. By racking your focus from near to far, you can see the plane of focus slide throughout your image.
In addition to that selective focus, you're also able to get infinite focus on a plane that's not parallel to the sensor, even at the brightest aperture. This produces otherwise impossible focal effects, and can be used – or abused – to great creative effect.
While the 50mm and 80mm Lensbaby Edge optics are more apt for portraiture, the Lensbaby Edge 35 is a dream for street photographers who want to add a unique flourish to their images, creating subtle streaks of selective focus or carving out great swathes of blur.
