35mm F1.4 DG HSM
Many avid photographers will definitely prefer this 3 5mm lens to the more conventional 50mm. Using a leading-edge design and state-of-the-art production technology, we’ve honed its performance to the point where it can do full justice to the expressive power of the very latest digital cameras. A t low apertures, for example, it can perform like a wide-angle lens, while if it’ s opened up to F1.4, it will give the background a pleasing bokeh effect and make the subject pop like a mid-range telephoto lens. What makes this lens so desirable is the wide scope it provides for artistic expression.

120-300mm F2.8 DG OS HSM
Although high-function digital cameras now deliver improved picture quality at high-ISO settings, adjusting your lens to a large aperture is still the most effective strategy for action shots. And even if you have to take the shots from a less-than-ideal position, as is so often the case when shooting sports or on-stage action, this zoom lens, with its maximum focal length of 300mm, lets you open up the aperture all the way to F2.8. In other words, when conditions are difficult, this high-performance lens gives you more scope to express yourself in the shots you take.
