* Rumors and Speculation: There have been persistent rumors circulating about a potential Canon RF 70-135mm f/2L lens. These rumors often originate from websites specializing in Canon news and leaks, like Canon Rumors, but it's important to remember that they are not confirmed by Canon.
* Desirability: A lens like this would be highly desirable for several reasons:
* Fast Aperture: An f/2 aperture across the zoom range would be exceptionally bright, offering excellent low-light performance and shallow depth of field capabilities.
* Professional Grade: Being an "L" series lens, it would be expected to have top-notch build quality, weather sealing, and exceptional optical performance.
* Unique Range: The 70-135mm range is intriguing. It could offer a sweet spot between traditional 70-200mm lenses and shorter zooms, potentially being more compact and lightweight.
* Challenges: There are also challenges in manufacturing such a lens:
* Complexity: Designing and manufacturing a zoom lens with such a wide aperture and high optical quality is technically demanding.
* Cost: A lens like this would likely be very expensive.
* Size and Weight: Even with a slightly shorter zoom range, maintaining an f/2 aperture could still result in a large and heavy lens.
* Current Alternatives: Currently, photographers looking for fast telephoto options have these alternatives:
* 70-200mm f/2.8 L lenses (Canon and third-party): These are the standard choice for professional telephoto zoom needs. Canon offers several excellent 70-200mm f/2.8L lenses.
* Prime Lenses: Canon offers fast telephoto prime lenses like the 85mm f/1.4L, 135mm f/2L, and others.
In conclusion: While the idea of a Canon RF 70-135mm f/2L lens is exciting, it remains firmly in the realm of rumors for now. Keep an eye on reliable Canon news sources for any official announcements. Until Canon confirms it, treat the rumors with healthy skepticism.
