Photography RF Lenses RF24-105mm f/4-7.1 IS STM. RF24-105mm f/4-7.1 IS STM. 0.20 / 0.66 (at 24 mm), 0.34/1.12 (at 105 mm) The RF24-50mm f/4.5-6.3 IS STM is significantly smaller and lighter than Canon’s RF24-105mm lenses. In fact, it is almost the same size as the RF35mm f/1.8 Macro IS STM (approximately 63mm)! This makes it convenient in situations that call for a compact, mobile setup, such as travel or when shooting video with a gimbal. 3z4tr9.
