Testing a camera or lens requires precision setup and execution. Otherwise, the results are deceptive. Most photographers would rather shoot subjects other than test charts, especially with the complexity involved, but ... we want to see how well particular cameras and lenses perform. And more importantly, we find value in how the presentation of these results aids your photography gear decisions – and ultimately, your imagery. We shoot the charts so that you don't have to.
Shooting over concrete, guided by lasers and using expensive camera stands, precision test charts, custom test target holders and full-spectrum lighting, we capture repeatably-accurate test results to present to you here.
