Sure, this may not be the super fast f/2.8 you might crave in low light, but it gives you consistent exposure settings, which is excellent for shooting videos or capturing a series of images in changing light conditions without any noticeable shifts in exposure.
Superior Optics for All Conditions
As photographers, we understand the unpredictable nature of light and environment. The Canon EF 17-40mm f/4L USM lens boasts three aspherical lens elements and a super UD glass element.

The Silent Performer: USM Autofocus
Imagine trying to discreetly capture a candid shot during a wedding, and your lens decides to autofocus with the subtlety of a jet engine. Thankfully, the ring-type Ultrasonic Motor (USM) on this lens ensures fast and silent autofocusing. This means you can shoot in confidence that your moments aren’t being disturbed by noise competition from your equipment.

Artistic Expression with a Rounded Diaphragm
The rounded seven-blade diaphragm doesn’t just add a quality bokeh but also facilitates selective focus techniques. Imagine the soft, buttery background blur in your portraits or selected sharpness on a forest trail—these effects make your images feel both professional and artistically composed.
