Canon RF 28mm f/2.8 STM 28mm
Weighing just 120g with a pancake design, this lens stands out as an ultra-portable full-frame 28mm f/2.8 prime that delivers edge-to-edge sharpness via three aspherical elements and Super Spectra Coating. Its budget-friendly price and 9-inch minimum focus distance make it a discreet, all-day companion for both full-frame and APS-C EOS R bodies. This lens is best for travel photographers and street shooters who prioritize a lightweight, low-profile setup without sacrificing wide-angle capability.
