(Pocket-lint) - On 5 September 2018, Canon announced a large caller merchandise to its line-up: the EOS R full-frame mirrorless. In truthful doing the Japanese institution created a full caller lens line-up: EOS RF.

What EOS RF lenses are available?

Back successful 2018 determination were conscionable 4 EOS RF lenses available, but since the scope has expanded considerably. All lenses successful this scope are designed to screen the R's full-frame sensor size - each has a 54mm diameter and 12-pin RF equine - but don't confuse the EOS M cameras series, which person smaller APS-C sensor sizes and usage EF-M lenses.

Unlike full-frame EF lenses, arsenic utilized successful Canon DSLR cameras, the company's RF lenses are designed to cater for the shorter 20mm flange backmost region of the EOS R mirrorless system. This opens up caller imaging and solution resoluteness possibilities astatine a smaller standard than DSLR equivalents. But they travel with often sizeable asking prices.

Here's the existent EOS RF lens line-up astatine the clip of writing:


  • RF 50mm f/1.2L USM
  • RF 50mm f/1.8 STM
  • RF 85mm f/1.2L USM
  • RF 85mm f/1.2L USM DS 


Prime Long Focal Length:

  • RF 800mm f/11 STM
  • RF 600mm f/11 IS STM



  • RF 70-200mm f/4L IS USM
  • RF 70-200mm f/2.8L IS USM
  • RF 24-105mm f/4L IS USM
  • RF 28-70mm f/2L USM
  • RF 15-35mm f/2.8L IS USM



  • RF 35mm f/1.8 Macro IS STM


What bash those acronyms mean?

There's a full batch of acronyms successful among that, truthful here's what they basal for:

  • USM = Ultra Silent Motor
    • As its sanction suggests, this is large for quiescent absorption and/or zoom operation
  • STM = Stepper Motor
    • Invariably noisier than the pricier USM, arsenic above
  • IS = representation stabilisation
    • Effectiveness varies per lens
  • DS = Defocus Smoothing
    • A lens coating for representation lenses, which further softens the bokeh
  • L = Luxury
    • The achromatic Canon lenses, with superior optical quality

All EF lenses via adaptor

In UK and Europe, the EOS R lone ships with an EF lens adaptor included successful the box. Canon's anticipation present is that existing DSLR customers volition beryllium pleased all its existing EF and EF-S lenses volition beryllium compatible from the off.

We, however, work it arsenic a crook successful confidence: if the caller RF lenses are truthful great, past wherefore not simply connection the enactment to see the adaptor oregon not? It tin beryllium bought separately, however, which is arsenic perplexing (who volition request two?).

What of Canon's future? EF-M, EF-S, EF and RF

The different information with RF is that it's pitched astatine the high-end; Canon already has a mirrorless range, the EOS M, which is designed for the user marketplace and there's nary cross-over betwixt the two. Mirrorless doesn't mean nonstop compatibility: EF-M won't relation with RF and there's nary adaptor available.

The large question, really, is what the EOS R meant for the aboriginal of Canon? Back successful 2018, erstwhile the EF lens line-up was 31 years into life, the Japanese institution was keen to amusement ongoing enactment - adjacent launching the world's lightest 400mm f/2.8 and 600mm f/4 lenses for EF mount. But that was small much than a gesture, really, arsenic of 2020 Canon has called clip connected EF lenses, confirming that its mirrorless marketplace is its sole aboriginal intent.
