Unlock the full potential of your camera. This lens is as sharp or sharper than my prime lenses. It has a professional quality build to go along with the unmatched sharpness. If you want to get serious about your photos then this lens covers you from 18-35mm (27-53mm). The only limitation (negative) is the limited focal length...but up until this point in time only prime lenses had the specs of this lens. Actually, this lens is in a category of its own; no other zoom lens has a constant 1.8f.
Outstanding images with this in conjunction with my 300mmF2.8L. Frustrating that it does not work with the 100-400 F4.5L ll USM, while it did work with the original version of this lens, (although this was not consistent). I also own the 1.4x extender. Curious that it works with all of the above mentioned lenses.
