優點:
a professional wide-zoom at f:2.8 also metal barrel and quality lens struction built-up, nice handcraft texture feel, unlike 16-35, simple and plastic barrel, like a toy feel at f4.... 17-35 f2.8 with such price, it most strong and best at price/quality ratio. also with important aperture range for previous bodies.
缺點:
a bit heavy, a slightly vignetting, but even 14-24 or 16-35 also have such problem.
評價:
professional quality built-up lens, good & balance handling, practical & useful range, unlike 14-24 ultra-wide zoom, bulky, unable to add front filter, actually not practical with all the way ultra wide range, film feel photo with natural image, not hard sharp or not soft. photos with amazing texture.
