Welcome back to #LensdayWednesday, where each week we will be highlighting the wide range of Canon lenses. In this episode, Senior Pro Market Specialist of Field Education and Engagement, Kelly Anderson (kellyanderson_photo) shares why the small, inexpensive and lightweight EF 40mm f/2.8 STM is such a special lens. The EF 40mm f/2.8 STM lens works great on both EF and RF camera mounts. Kelly shows how this is possible along with other technical details. #LearnwithCanon #TeamCanon
