We’ve tested 7 just for the Canon EF lens mount and noticed a big variation not only in price and features, but crucially in optical performance, with some fairly surprising results. Primes on the other hand often perform better, and there’s a large range of both own brand and 3 rd-party 35mm options to chose from. Standard zooms covering wide-angle to short telephoto focal lengths are great for versatility, but the wide-angle end of the zoom is often optically weak, offering poor edge sharpness, heavy corner shading and noticeable chromatic aberration even with the aperture stopped down.
