Review on Ultra Wide Angle Zoom Lens for SLR Cameras - Canon EF 17-40mm f/4L USM by Mohd Taufik ᠌

It was the first Elka for the 50D, to replace the 18-200. In terms of color reproduction and sharpness - like heaven and earth, autofocus hits quickly and accurately. On 50D (crop) the lens works like a staffer. Very satisfied with the purchase. Its pros: Elka, that says it all. The sharpness is incredible. Excellent construction, quality built. Dust and moisture protection. Excellent autofocus. Excellent value for money. Different cons: Aperture (indoors without a flash is difficult), i. E. a bit dark And there are no shortcomings for a lens of such price and quality!
