SUMMARY
Canon is rumored to be preparing to update its RF super telephoto prime lens lineup with built-in teleconverters, similar to Nikon's offerings. The potential new lenses, which could include replacements for the RF 400mm f/2.8L IS USM and RF 600mm f/4L IS USM, along with a 300-600mm zoom, might be announced in late May. While a patent application outlines lens designs, it does not mention integrated teleconverters, leaving some speculation about this feature. These professional-grade lenses are anticipated to be very expensive, with current models already costing over $13,000.
