Frequently Asked Questions
Does the Canon RF 135mm f/1.8L IS USM have image stabilization, and how effective is it?
Yes, this lens features built-in optical image stabilization (IS), rated at up to 5.5 stops (or up to 8 stops when combined with IBIS on some RF bodies). In real-world use, this allows for sharp handheld shots at substantially slower shutter speeds-especially useful for low-light indoor portraits or events.
Is the RF 135mm f/1.8L IS USM suitable for sports or action photography?
While primarily targeted at portrait and event shooting, the lens's fast, accurate autofocus and image stabilization make it capable for indoor sports or isolated action shots. However, some users may prefer a zoom for increased flexibility at typical sports distances.
How does the RF 135mm f/1.8L IS USM compare to the EF 135mm f/2L USM?
The RF version delivers sharper images, faster and quieter autofocus, and includes image stabilization-none of which the EF version matches natively. The trade-off is increased size, weight, and a higher price, but the overall performance leap is significant for demanding shooters.
Can this lens be used for video work?
Yes. Its fast, silent autofocus, robust IS, and beautiful subject separation make it excellent for interview, documentary, or cinematic use, especially on gimbals or handheld with the latest RF bodies.
Is this lens weather-sealed?
Yes, it features full weather-sealing with gaskets around critical points, making it suitable for professional use in challenging outdoor conditions.
What filters does this lens use?
The RF 135mm f/1.8L IS USM accepts standard 82mm screw-in filters, easily sourced from most pro camera retailers.
