Canon Adds Classic 135mm Prime To RF Mirrorless System

If you’re a Canon EOS R system user, there’s a lot to like about the recently released RF 135mm f/1.8L IS USM short telephoto prime. It combines the classic 135mm focal length with a fast maximum aperture of f/1.8 and built-in optical stabilisation offering up to 5.5 stops of correction for camera shake. This extends to eight stops with the EOS R series camera bodies that have in-body image stabilisation.

The optical construction comprises 17 elements in 12 groups with three special types that have ultra-low dispersion (UD) characteristics to correct for chromatic aberrations. Both Canon’s Air Sphere Coating (ASC) and Super Spectra Coasting (SSC) multi-coatings are used to minimise the internal reflections which otherwise cause ghosting and flare. The autofocusing drive employs Canon’s

Nano USM motor for fast and quiet operation.

The minimum focusing distance is 70cm, giving a maximum reproduction ratio of 1:3.8. The nineblade diaphragm promises to produce smoother out-of-focus effects.

Externally, the RF 135mm f/1.8 has a weathersealed construction with a fluorine coating on the exposed surface of the front element to help repel moisture and grease. There are two customisable Lens Function buttons and the RF system’s multifunction Control Ring which can be set to adjust the shutter speed, aperture, ISO or exposure compensation.

The lens measures 130mm in length and has a diameter of 89mm, so the screwthread filter fitting is 82mm. The weight is 935 grams.

The RF 135mm f/1.8L IS USM is available now priced at $3,969. Canon Australia provides a fiveyear warranty for EOS R system cameras and lenses purchased from one of its authorised resellers.
