High-precision, high-performance, wide-angle view – the EF 16-35mm f/4 IS USM
This is the budget version of my favorite lenses 16-35:2.8. The big difference that makes the lens cheaper is that the maximum aperture is 4.0 instead of 2.8. This means that you may raise the ISO one step to achieve the same exposure time as with the 2.8 lens. Today’s cameras are so good at high ISO that the lens is good enough for most users.
The EF 16-35mm f/4L IS USM provides greater versatility for professionals and keen enthusiasts who regularly capture wide-angle perspectives – such as landscape or architecture photographers – or those who typically shoot in confined spaces. The lens offers wide-ranging flexibility, with first-class optical construction and a fixed f/4 aperture providing clear, sharp results even in the most challenging situations.
The new EF 16-35mm f/4L IS USM is Canon’s first ultra-wide L-series lens to feature Canon’s signature optical Image Stabilizer (IS) technology, which offers a four-stop advantage over non-IS lenses and helps to ensure that shots are always captured with precision detail. The newly-designed IS system also features a number of additional improvements, including gyro sensors for greater accuracy in traditional shooting or when capturing panning motion.
First class optical technologies and design
Photographers can quickly achieve focus using the powerful, fast and silent autofocusing (AF) performance of Canon’s pioneering ring-type Ultrasonic Motor (USM) – ideal when shooting in AI Servo AF mode. Complete control over image composition is also possible using the lens’s full-time focus ring in manual and AF modes, giving photographers the freedom to fine tune focus on demand.
Designed to deliver the highest image quality, the lens’s optical structure includes two Ultra-low Dispersion (UD) elements to minimise chromatic aberration and eliminate colour blurring. Super Spectra Coatings reduce ghosting and flare, while fluorine coatings on the front and rear elements prevent dust and water drops sticking to each element. Photographers can also enjoy beautiful background blur and bokeh thanks to the lens’s 9-blade circular aperture.
The lens’s exterior is optimised to provide exceptional ease-of-use and professional performance. The high-grade design includes a compact and lightweight shape that’s comfortable to hold, whilst providing intuitive access to the zoom and focus control. A leather-texture coating also provides a professional feel.
