When comparing the offerings of Sony, Canon, and Nikon, it becomes evident that Sony has achieved a formidable presence in both APS-C and full-frame mirrorless systems, boasting a vast array of lenses for each format. Canon and Nikon, on the other hand, entered the mirrorless camera market later and have focused primarily on developing an extensive range of high-quality full-frame lenses, leaving APS-C with limited options.
As of now, Canon offers 28 RF lenses for full-frame cameras but only three RF-S lenses for APS-C cameras. Nikon, too, has a similar ratio with 30 full-frame lenses and merely four APS-C lenses. While Canon has recently released the EOS R7 and EOS R10 models, it remains understandable that they have only introduced three APS-C lenses thus far. Nevertheless, Canon’s history of modest investment in the APS-C sensor format is worth noting, as their previous EF-M mirrorless system failed to gain traction.
