lenses for the EOS R.

This new lens is big, and it’s

expensive, but that’s par for the

course with Canon’s L-series lenses.

Once you take that on board, we

don’t think you’ll be disappointed.

Mirrorless cameras may be smaller

than their DSLR counterparts but

that’s as far as their advantage goes.

The lenses are just as big, and

although the RF 15-35mm is a hair

smaller than its EF counterpart, the

Canon EF 16-35mm f/2.8L III USM

(which measures 127.5mm in

length) is still a pretty big lens,

important as the promise of its

optical superiority.

Of course, like all Canon’s native

RF lenses, the 15-35mm possesses

the fully customizable control ring.

This can be assigned to virtually

any function you choose, from

aperture, to white balance, to ISO,

and can be taken to a Canon service

centre for ‘de-clicking’ should you

want to use it for video purposes.

What you don’t get is a focus

distance scale, but if you switch the

lens to MF mode, you do get one in

Expensive, but

with its fast, f/2.8

aperture and

5-stop IS, this is

one to watch

especially on an EOS RP, but also

on the EOS R. But where this lens

scores over the EF DSLR version, is

that it goes 1mm wider to 15mm

and still packs in Canon’s 5-stop

Image Stabilizer (IS) technology.

It’s Canon’s widest ever zoom

lens to feature a constant f/2.8

aperture and, to complete the trinity

  high speed for stills, but also glide
  them near-silently for video.
  Since it’s comparable in size and
  heft to its EF predecessor, if you’ve
  used that lens then you should feel
  right at home here. The RF
  15-35mm is rugged, robust and
  deserving of its red ring, with the
