Canon recently released its 16-35mm f/4 IS lens for full-frame bodies. When I got the chance to document the last leg of NYC's High Line park, I thought it would be a great chance to bring along this newbie piece of glass and see how she did.
The 16-35m f/4 is supremely designed and fun as hell to use. The image stabilization comes in handy when you want to go just a little slower on the shutter speed, or when you are moving around a lot and don't have a moment to pause and be absolutely still.
The sharpness is terrific across the frame, but one quirk I did notice was that it seemed to wash out color as you move toward the edges. Look at the sky in my shots, the blue hue fades and shifts to magenta on the sides. Despite this, I would still recommend the Canon 16-35 f/4 for anyone needing a super-wide angle and extra stabilization.
