The RF mount has seen some extreme lens designs, with Canon entering new territory with options like the revered 28-70mm f/2L. It seems they have no intention of slowing down, as another interesting design has arrived, this time sure to please wildlife and sports photographers.
A recent Canon patent has surfaced for the Extender RF 100-300mm f/2.8 1.4x lens. While such a lens is not unheard of, as both Nikon and Sigma manufacture 120-300mm f/2.8 lenses, it will be the first such full frame lens with a built-in teleconverter. , can effectively turn it into a 140-420 f/4 lens. lens when participating.
I wonder if this is why we haven’t seen the RF 300mm f/2.8 lens yet, as Canon may be exploring the idea of replacing it with a lens like this. That said, just because a patent comes out doesn’t mean the final product will hit the market, but I believe we’ll see some sort of 300mm f/2.8 lens eventually. That’s for the RF mount, whether it’s a prime or a zoom lens. .
Having owned and used the Sigma 120-300mm f/2.8 for several years, I can say that it is an extremely versatile and useful lens, and I wouldn’t be surprised if Canon chose to go the zoom route to fill the shorter super-telephoto focal length. length. I doubt such a lens would be quite popular. Hopefully, we’ll hear more soon!
