Canon 17-40mm f/4L Lens Review at ePhotoZine
ePhotoZine have just reviewed the Canon 17-40mm f/4L lens.
“As mentioned in the opening paragraph, the lens is almost legendary and does produce fine results. But with the ever-increasing resolution of high-end sensors and Canon’s recently stated intention to produce more full frame sensors, can this lens keep up with the game. It is widely recognised as a lens with good contrast and control of distortions and the handling of chromatic aberrations is pretty good also, so more interest during the test procedure was placed on the pure resolving power of the lens. The answer is that, as things stand at present, it is fine. But, and we are talking the top end of the existing cameras here (1Ds MkII at 16.7mp), any more resolution and the lens will start to struggle.”
