What We Like
+Lightweight at 507g and compact design, making it easy to carry for extended telephoto reach
+Budget-friendly entry-level telephoto option with versatile 75-300mm range and 4.3x zoom
+Dust and moisture-resistant construction for outdoor use
+Sharp, especially in the center frame at wide focal lengths with decent resolution at telephoto reach
Worth Knowing
−No optical image stabilization, critical for this focal length; requires in-body stabilization or high shutter speeds
−Image quality deteriorates significantly at longer focal lengths with color fringing and softness, particularly at 300mm
−Slow and audible DC motor autofocus struggles in low-light conditions with frequent focus failure
−No fluorine coating makes the lens more susceptible to fingerprints and smudges

General

About This Lens
The Canon RF 75-300mm f/4-5.6 is an entry-level, budget-friendly telephoto zoom designed for beginners and cost-conscious photographers seeking extended reach on Canon's RF-mount mirrorless system. While its lightweight, compact build and affordable price make it attractive for casual wildlife and sports photography, the lens suffers from poor image quality at the longer end, slow autofocus in low light, and the lack of optical stabilization—all significant compromises at this focal length range.
