Canon's RF 300-600mm F5.6LIS VCM Lens is Coming

According to Canon Rumors, Canon will release an RF 300-600mm telephoto zoom lens in 2026. There are currently two versions of this lens: one is the RF 300-600mm F4-5.6LIS USM with a variable aperture, and the other is the RF 300-600mm F5.6 LIS VCM with a constant aperture.

Analysis suggests that the possibility of Canon releasing the RF 300-600mm F5.6LIS VCM lens is relatively high. To control weight and size, this lens may use DO (doped optics) elements. Furthermore, the 2026 FIFA World Cup in the USA, Canada, and Mexico will begin in June, which may be the opportune time for Canon's new lens to be unveiled.
