Camera lenses can be very pricey, but help is at hand, courtesy of filmmaker and innovator Tim Irwin. Irwin (Instagram: @functionalfilms) has produced a new low-cost prime lens called the Simple 90. This 90mm prime is made in-house by Irwin himself, who 3D prints the barrel and self-assembles each and every lens. Only the two glass elements and assembly screws are outsourced. The lens elements are arranged in a cemented achromatic doublet, which results in image quality characterized by a sharp central region which transitions into soft, ethereal bokeh towards the edges and corners of frame.
