Problem

Photographers and creators who need an ultra-wide perspective often trade portability for image quality, or they must manage large, heavy lenses that complicate travel and handheld shooting. Many ultra-wide lenses also require large filters, increasing cost and weight for multi-lens filter kits.

• Bulky ultra-wide lenses make travel and handheld work harder.
