Product spotlight: Lensbaby Burnside 35

The new Lensbaby Burnside 35 is an all-metal, non-tilting lens that brings the user variable control over vignette and bokeh through a gold anodized slider on the barrel. Images from the 35mm f/2.8 lens have a large, bright central area of sharp focus surrounded by swirling bokeh that can be strong or subtle.

The effect slider can be used to adjust center brightness and in-camera vignette in a four-stop range. The aperture range adjusts from f/2.8 to f/16 with a six-blade internal aperture and an eight-blade secondary internal aperture for the effect slider. The minimum focus distance is six inches.

The Burnside 35 is made for full-frame and crop sensor cameras and comes in models compatible with Canon EF, Nikon F, Sony A, Pentax K, Micro 4/3, Sony E, Fuji X, and Samsung NX camera mounts. $499.95
