Canon rumours said that Canon would be announcing an ultra-wide zoom lens for their R system designed for APS-C cameras like the R100, R50, R10 and R7. We hope to have some specs in the coming hours and pricing information.
Is the RF-S 10-18 too wide for you, or do you enjoy capturing landscapes. There isn't too much you're going to miss with a 10-18mm. Excellent focal range for architecture and landscapes.
