Impressively, the new RF 10-20mm F4 is incredibly lightweight, tipping the scales at a mere 20.1 ounces (570 grams). This is less than half the weight of the 11-24mm F4 DSLR lens, which weighs a substantial 41.6 ounces (1,180 grams). This significant weight reduction makes the RF 10-20mm the lightest F4 zoom lens in Canon’s lineup. The contrast between this mirrorless lens and its DSLR counterpart is truly staggering.
